The Avidyne Equipped Cirrus Upgrade

ByHank Gibson October 27, 2020October 27, 2020

A History Lesson

11 years ago, in April of 2009, the Avidyne Corporation unveiled the much bally-hooed Release 9, or R9 as it is commonly known, as a hardware replacement for the Avidyne EX5000 Entegra system in Cirrus Aircraft. The Entegra system was way outdated by that point. Even though Avidyne was the first company to put together a glass PFD in a single engine piston airplane, the company had quickly fallen behind Garmin in keeping up with the ever changing technology landscape.

Rewind to 2008. Cirrus had been going strong with the Avidyne Entegra since the SR20 and SR22 went to full glass in 2003 (a PFD and an MFD; prior to that, Cirrus aircraft only had an MFD with steam gauges and a Sandel Electronic HSI). Cessna, on the other hand, vaulted past the Avidyne Entegra and went straight to the Garmin G1000 in it’s aircraft, starting in 2004 with the 182 G1000 and 2005 with the 172 G1000. Beechcraft and Columbia went to the G1000 (Columbia started with the Avidyne as well) in 2005.

Garmin’s technology in 2007 was so much better than Avidyne’s technology that Cirrus decided to switch. I’m sure there were many promises made by Avidyne to Cirrus about what Avidyne was working on (the R9), but the G1000 was out there, available, and being used in a lot of different airplanes with very good results.

So, in 2008, Cirrus made the switch from the Avidyne Entegra to the Garmin G1000, dubbing it the Cirrus Perspective by Garmin avionics package. Avidyne finally got the R9 to market in 2009, but by that time, Piper was the only airplane manufacturer left putting factory Avidyne panels in their airplanes, and they switched to G1000 later that year.

The R9 is a fabulous product. It’s fully integrated, has great graphics, has fully redundant displays, a QWERTY keypad (which, by the way, Garmin didn’t do for another 8 years), and a lot of other neat features. There’s a bit of a learning curve, but it’s a really good product for what it is.

Avidyne, though, was late to the game with their technology. By the time it debuted in 2009, all the GA aircraft manufacturers had long since switched to the Garmin G1000 and weren’t looking back. That left Avidyne with the retrofit market for the many different Avidyne Entegra Cirrus aircraft out there. The only problem was, the retrofit was $80,000 ($95,000 if you wanted to throw in the DFC 100 Autopilot, which is a must have) and not many owners were up for paying that much money, then or now.

To sum up our brief history lesson, Avidyne knew the Entegra needed to go, but couldn’t get the R9 out quickly enough to convince anyone to stick with Avidyne products. The retrofit market didn’t amount to many sales, so Avidyne doesn’t even make the R9 anymore.

As a side note, I really, really like the Avidyne R9 and am sad that it didn’t make it into more airplanes.

So, when the Avidyne Entegra starts to have issues, what’s an owner to do? Keep reading!

There is Hope

There are thousands of Cirrus aircraft out there flying with the Avidyne Entegra instrumentation, which is basically 20 year old technology (I’ve had a computer engineer tell me the programming in an Entegra is Windows 98 tech). These things are going to start having problems at some point (many already have), but what solution do owners have that is cost effective and get’s them new technology?

Remember that little company named Garmin? Well, they have come through again. Announced this summer, the Garmin G500 TXi is now certified as a replacement in the Cirrus Avidyne Entegra equipped aircraft. This means pulling out both the PFD and MFD and replacing them with the G500 TXi on both sides. Engine data is also displayed on the G500TXi MFD, including the percent power and TIT indications, if equipped.

The cost for the panel? Two 10.6″ G500 TXi’s run about $16,000 apiece for the units, not including labor. $32,000 for a brand new panel isn’t terrible. Plus, the G500 TXi’s work with the DFC90 autopilot if the Cirrus is already equipped with it. If not, the Garmin GFC 500 autopilot is now approved for the Cirrus at a relatively low price of $7,000, including the servos.

Still have the original Garmin 430s in your Cirrus? Upgraded to the Avidyne IFD 540/440 stack? Put in dual GTN 650Xi’s? Put in a GTN 750Xi? All are compatible with the G500 TXi panel.

Want to upgrade everything? It does get kind of pricey at that point, but for just equipment, the cost for a complete panel conversion is somewhere in the area of $65,000 plus labor, still below what the R9 cost, but not cheap either. That would include 2 G500 TXi’s, 2 GTN 650Xi’s, a GFC 500 Autopilot, and all the engine monitoring equipment that the G500 TXi would need.

Thankfully, some new technology has finally come to the Generation 1-3 Cirrus. Oh, and by the way, your steam gauge Cirrus is fully upgradable as well.

Setting Standards

Type Clubs Lead By Example with Standard Operating Practices

This article appeared in the May 2019 edition of EAA’s Sport Aviation Magazine. It is used with permission. For other articles by Charlie Precourt, please visit EAA.org and join for a full subscription.

Imagine a year when there are no fatal accidents in general aviation. Does that seem impossible? The airlines achieved that many years ago, and so can we if we focus on the right things in our safety pro- grams. In fact, the overall trend in GA accident rates over the last few years is very encouraging. AOPA’s Air Safety Institute published its annual GA Accident Scorecard recently (see www.EAA.org/ extras), revealing fatal accidents from 2008 to 2017 are down more than 30 percent. Nevertheless, there were 185 fatal accidents in 2017, so we still have a long way to go. But, there are many developments in safety programs across GA that can keep the trend going.

One such development that I’ve advocated through a couple of type clubs is establishing standard operating practices (SOP). When I flew for both the U.S. Air Force and NASA, we had what we called standard operating procedures. They were the law for our flying. That is, we had to follow them procedurally because the folks that paid our salaries said so. The objective was to ensure we all used the same playbook, minimizing the risk that one of us might develop a bad in-flight habit that increased risk to the organization.

One way to think about SOPs is to recognize the difference between procedure and technique. For example, you have to follow the manufacturer’s pilot’s operating handbook (procedure)where it says to lower the landing gear before landing. If you don’t, you are in for a bad day. However, it does not tell you exactly when to lower the gear; that’s left to technique.

In the middle, between procedure and technique, is a best practice. In this example, lowering the gear just before the final approach fix is a “standard practice.” It is the generally accepted “best” place to lower the gear. In GA, however, aircraft owners don’t generally answer to a boss, so I prefer the term practices instead of procedures.

However, whether or not someone is paying us to fly, following best practices just makes sense. If you have a good set of practices, they enable you to do things the same way every time, leaving lots of brain cells to manage the unusual, the things that might go wrong. The safest approach to accomplishing a flight task is one that leverages consistency. On the other hand, if you are inconsistent, doing flight tasks differently each time, you’ll always be struggling to keep up. So, in my involvement with the safety committees for both the Malibu Mirage Owners and Pilots Association and the Citation Jet Pilots Association, there has been broad acceptance of recently developed standard operating practices.
The good news in this development is that a culture of safety is growing broadly across most sectors of GA through these type club initiatives. Perhaps more importantly, there is much to learn from each other about the effectiveness of these various initiatives. EAA has seen a four-year drop of 47 percent in fatal accidents among homebuilts! So, there must be something right going on there — a major focus on appropriate transition training before flying a new homebuilt (as a standard operating practice) is paying off.

So, what is covered in the SOPs these type clubs have developed? The following outlines the kinds of standard practices other type clubs have set up and represent SOPs you could establish for yourself regardless of the type of aircraft you fly. You just have to fill in the blanks for your particular type and commit to sticking to them in your flying. These are notional and are practices (not mandatory procedures). They don’t tell you how to fly your aircraft; they give you things to think about when you do. If you take a bit of time to set your own SOPs and then stick with them, you’ll be a far safer pilot. Here are some ideas:

Duty Day

Set the maximum number of hours of flight time during a calendar day and rest hours off between flying days. One example is a maximum of eight hours in the air and a minimum of 10 hours off until flying again.

Cargo

Establish best practices for what you will carry as cargo. One example is no lithium batteries in the baggage compartment.

Flight Planning and Preparation

What are your limitations for the types of flight you’ll take on? Consider SOPs such as designating a suitable alternate airport for all flights. Another might be for first flights after significant maintenance, such as no flight at night or in IMC until a day-VMC functional check flight has been done.

Runway Field Length Guidelines

Establish an appropriate minimum field length for your aircraft and commit to not going into shorter fields. Consider sea level operations and high-altitude airports as well.

Surface Operations

What should be your maximum wind conditions for taxi, takeoff, or landing? Maximum acceptable crosswinds on landing? Set them in your SOP and stick to them.

En Route

Consider establishing practices like no non-operationally necessary conversation below 10,000 feet MSL, during any segment of an approach procedure, or during the last 1,000 feet before leveloff during climb or descent. Also consider declaring “minimum fuel” when the fuel state becomes less than fuel to destination plus 45 minutes at current burn, even if flying day VFR.

Approach and Landing

Consider establishing personal minimums in your SOPs for things like visual approaches. Perhaps use a 1,500-foot ceiling and 3 miles’ visibility for day and 5 miles for night, even though these exceed the FAA’s requirements.

Pilot Limitations, Training, & Currency

FAR Part 91 rules allow us to fly with pretty marginal levels of currency. Consider setting your own SOP to something more appropriate for the kind of aircraft you fly and the kind of flying you do in it. For example, consider these ideas as SOPs:
- If you have less than 100 hours of time-in-type or have not flown at least 15 hours as pilot in command in the last 90 days, use a minimum planned fuel reserve of one hour.
- Also, if flying IFR in this situation, use a minimum visibility for takeoff of 1 mile.
- On instrument approaches, increase the published minimums by one- half mile visibility and add 200 feet to the decision altitude or minimum descent altitude.
- Perform landings at a weight that allows a full stop in 60 percent of available runway length.
- Consider an SOP that establishes you will fly with a CFI on a refresher flight before flying as pilot in command if you have not logged at least an hour of flight time and one takeoff and landing in an aircraft of the same type within the preceding 45 days.
Maneuver Standards

Wherever there are “techniques” associated with things like takeoffs and climbs, cruise, use of autopilot, power settings, and approaches and landings, you can write down your preferred technique as your own SOP. Describe each maneuver in enough detail (speeds, altitudes, power settings, configurations, etc.) to define a routine you will use each time. This ensures you fly consistently each flight and leverage the power of the standard operating practice, that is, to give you the bandwidth you need should you encounter an unexpected event or an emergency.

SOPs are among the exciting concepts underway to make safety programs work for us. Hats off to type clubs like MMOPA and CJP and many others that are taking the initiative. But even if you’re not in this kind of group, you can still set up your own SOPs. Let’s all look forward to our first year in GA without a fatal accident — and let’s make it soon!

Fly Away Destination: Sedona, AZ (KSEZ)
ByHank Gibson October 21, 2014October 21, 2014

Looking for somewhere to take a trip this fall? Sedona, Arizona should warrant strong consideration. Just shy of 100 miles north of Phoenix, Sedona is one of the most beautiful areas in the southwest United States. From Texas, depending on how fast your airplane travels, you could make it to Sedona in a day, with a couple of stops in between. You’d definitely want to spend a few days to enjoy the scenery and maybe jump over to the Grand Canyon while you’re in the area.

The Airport

As you approach the Sedona Airport (KSEZ), you become somewhat distracted by the scenery around you. Don’t be too distracted as the approach is a little tricky. If you are landing north, on Runway 3, the calm wind runway, don’t let the surroundings fool you. Stay on that PAPI and don’t be short, as the runway is on a 500 foot mesa. In instrument conditions, the MDA for the RNAV approach to Runway 3 dumps you out about 1,300 feet above the airport elevation, giving you plenty of time to set up to land.

When using runway 21, don’t make your pattern too wide as there are some pretty tall rocks (around 7,000 feet) north of the field. The Airport/Facilities Directory gives a warning to pilots in strong southwesterly wind conditions. Be aware of strong downdrafts coming in on final for runway 21.

The runway itself is in excellent condition, and plenty long at just over 5,000 feet. The FBO is a little dated, but the folks there are great. They were redoing the ramp this summer, so beware of that. Airplane parking is no problem, but actually getting to the FBO is a little tricky. The Mesa Grill is a very nice good restaurant just a short walk from the FBO. When I was there, I chowed down on a buffalo burger. It definitely hit the spot.

What To Do

Sedona is the outdoorsman’s paradise. Starting off, to get a great overview of the area, hop on the Red Rock Scenic Byway (SR 179) about an hour before dusk. You’ll get to see some spectacular views while it’s still light, then you can’t beat the sunsets in Sedona.

For hiking, you have a myriad of options, from the Cathedral Rock, to the Oak Creek Canyon, to the Devil’s Bridge Trail, all are beautiful, though most are not for the faint of heart (especially the Devil’s Bridge). Even though the fall is cooler, make sure you pack plenty of water for the hikes.

Want something to do in the evening? Go up to the Chapel of the Holy Cross to watch the sunset. After the sun goes down, go do some stargazing. You’ll get to take a tour of the stars at the Sedona Star Gazing location in Oak Creek. You are shown all the constellations and stars by professional astronomers, and blankets and chairs are provided.

Art connoisseur? You’ll find plenty of art galleries around town with a ton of beautiful, original artwork. There are also several theaters and golf courses around Sedona, giving everyone a little bit of everything.

If you’re up for it, the Grand Canyon is about a 2 hour drive north of Sedona, or a quick flight up to the Grand Canyon Airport (KGCN).

In search of a good getaway? Try Sedona. You’ll be sore from lots of hiking and sight seeing, but it will definitely have been worth it.
Avidyne Entegra Chart Updates
ByHank Gibson August 19, 2014

There are a number of airplanes out there equipped with the Avidyne Entegra PFD and MFD system, most notably the Cirrus SR20 and SR22 models from the early 2000s and the Columbia 350 and 400 from the same era. The Entegra is pretty simple and easy to learn, but doesn’t have the capability that it’s Garmin glass panel counterparts do (I have not, however, tried the R9, which could prove much more capable than it’s predecessor). I have found that pilots master the Entegra a lot quicker because of the reduced functionality.

One of the nice features of the Avidyne Entegra is the CMAX Chartview option. With a yearly subscription, you can get all the Jeppesen approach plates and airport diagrams for the entire US on your MFD. Just like your GPS, though, you have to update the charts monthly to keep them legal. After a period of time when you don’t keep up with the updates (I believe it is 90 days), then the charts disappear.

The update process is a little tricky if you don’t have someone to explain it to you. Once you go through it a few times, you’ll have it down pat. Here’s the process for the Avidyne Entegra Chart Updates.

Jeppesen Subscription

The first step in performing your Avidyne Entegra Chart Updates is to create an account with Jeppesen, who handles all the GPS NavData and MFD Chart updates for both Garmin and Avidyne. If you already have a Jeppesen subscription, you can skip down to the next section. To do that, simply go to jeppdirect.jeppesen.com, and then do the following:
- Click on Avionics Data on the upper left hand side
- Click “Purchase Avionics Subscription”
- Then, click on “Create Account” in the new users section
- Once you’ve created an account, login, then put in your aircraft information and select 1 update for the Avidyne Entegra EX500 EX 5000
- Click Continue at the bottom and you can put in your payment information
Software Needed

There are two different programs depending on if you have a PC or a Mac. If you have a PC, you need the Jeppesen Services Update Manager (JSUM). If you have a Mac, you need the Jeppesen Distribution Manager (JDM). Download whichever one you need, then login, and your updates will show up.

Downloading the Avidyne Entegra Chart Updates

First, we’ll go through the process of performing the Avidyne Entegra Chart Updates process for a Windows computer, using JSUM. You’ll need two 2 GB USB drives formatted to FAT 16. Here’s how to format to FAT 16.
- Go to My Computer after inserting the USB drive
- Right click on the drive
- Click on Format, then select FAT and press OK
Once the USB drive is formatted to FAT16, open up the JSUM program. Login and your updates will be displayed on the screen
- You’ll need to set the Avidyne CMAX Key Code
  - Right click the Avidyne Electronic Charts Service and click Set Avidyne Key
  - To get the key code, visit MyAvidyne.com and create an account using your JeppView subscription number and your serial number for your Avidyne MFD (found on the AUX page) and your PFD serial number (displayed on startup when the PFD is warming up)
  - Once you get the Key Code, copy and paste it in the window and click OK
- Click on the service and click Start
- The program should automatically detect the drive (if it doesn’t, click browse and select the drive)
- Click Continue and the charts will start downloading and automatically programmed to the USB drive
- If you are updating NavData on the MFD as well, follow the same steps as listed above in order to update the NavData
Next, we’ll go through the Avidyne Entegra Chart Updates process on a Mac, using the JDM program. You’ll need two 2 GB USB flash drives formatted to FAT 16 (the easiest way to format to FAT 16 is on a Windows computer, using the process above).
- Open the JDM program and login
- Insert the first USB drive
- You’ll need to set your Avidyne CMAX Key Code
  - Click Service Details under the Electronic Charts Service
  - Click Set Avidyne CMAX Key Code
  - Program automatically detects the USB drive
- Click and drag the Electronic Charts service over to the USB and release
- The service is downloaded and copied to the USB drive automatically
- Eject the USB drive
- Insert the second USB drive (or plug the USB drive in to your MFD, do the update, then reformat the drive) and follow the same steps for the NavData
Updated the MFD with the Avidyne Entegra Chart Updates

Once everything is programmed the your USB drives, the rest of the process is simple. Just go out to your airplane, plug in the first USB drive with the Electronic Charts on it, turn your battery on and the avionics master, and the system will upload the information automatically. Once it’s finished, turn everything off, pull the USB drive out, then insert the second USB drive and do the same thing.

Now, you’re all updated!

If you’d like to see a video on the process, Jeppesen has some very good videos on the updating procedure. The links are below. If you have questions, please contact Texas Top Aviation and an expert will help you through the process.

TBM Debuts the 960 at Sun N Fun
ByHank Gibson April 15, 2022May 1, 2022

This is a Press Release from Daher’s website, the maker of the TBM 960.

Sun ‘n Fun Aerospace Expo, Lakeland, Florida, April 5, 2022 – Daher today unveiled the latest high-end version of its TBM pressurized single turboprop aircraft family – the TBM 960 – which incorporates Pratt & Whitney Canada’s advanced PT6E-66XT engine and a fully digital e-throttle, along with a digitally-controlled cabin that incorporates an all-new environmental control system, LED ambience lighting and electrically-dimmable windows.

The TBM 960 was introduced at the Sun ‘n Fun Aerospace Expo in Lakeland, Florida, where Daher is exhibiting the first production airplane (exhibit stand #MD-22B).

“The TBM 960 is the quintessential TBM, representing the fifth evolution of our very fast turboprop aircraft family since the TBM 900-series’ introduction in 2014,” commented Nicolas Chabbert, the Senior Vice President of Daher’s Aircraft Division. “It takes the maximum advantage of today’s turboprop technology to provide digital control of the engine and the propeller.”

The TBM 960 retains the rapid speed of Daher’s TBM family while enabling lower fuel consumption. At Daher’s recommended cruise setting of 308 kts., the fuel consumption is only 57 U.S. gallons per hour, which is a 10% fuel economy compared to maximum cruise setting for more sustainability.

At the heart of this latest TBM version is the intelligent PT6E-66XT powerplant and Hartzell Propeller’s five-blade RaptorTM composite propeller, both of which are linked to the dual-channel digital Engine and Propeller Electronic Control System (EPECS).

With the EPECS, the PT6E-66XT’s startup is fully automated after a single-switch activation. The cockpit’s power lever is an e-throttle, using a single forward position from takeoff to landing – with the EPECS optimizing powerplant performance throughout the flight envelope while

Daher unveils the TBM 960 at Sun ‘n Fun Aerospace Expo

reducing pilot workload by integrating all functions and protecting the engine’s life. Analysis of engine parameters is driven by 100-plus smart data inputs.

The RaptorTM propeller is fully integrated into the propulsion system. It is specifically designed to reduce overall weight and improve the TBM 960’s takeoff distance, climb and cruise speed. Turning at 1,925 rpm during maximum power output, the Raptor contributes to limiting noise and vibration. Its sound level during takeoff is just 76.4 decibels, meeting the most stringent international noise standards.

With its G3000® integrated flight deck, the TBM 960 retains Daher’s e-copilot® concentration of technological innovation and safety systems in the TBM, which can be compared to an “electronic copilot.” This includes an icing protection system, flight envelope monitoring through the Electronic Stability and Protection (ESP) and the Under-speed Protection (USP) systems, the Emergency Descent Mode (EDM) function, as well as the game-changing HomeSafeTM emergency autoland system.

New to the TBM 960 is the Garmin GWXTM 8000 doppler weather radar with advanced surveillance features such as lightning and hail prediction, turbulence detection, zero blind range for close-in returns, and ground clutter suppression. The TBM 960 also is the first application of Garmin’s GDL® 60 next-generation data transmitter for automatic database upload and interconnection with mobile devices.

The TBM 960’s Prestige cabin extends Daher’s use of digital power inside the aircraft, featuring an all-new environmental control system, LED ambience strip lighting integrated into both sides of the overhead ceiling panel, and electronically-dimmable windows – all controlled by a PassengerComfortDisplay(PCD). Enhancementsinthecabin’sstyleandcomfortalsoinclude new ergonomically enhanced seats, USB-A and USB-C power plugs, individual cupholders and headset hangers for each occupant.

For the TBM 960, a fifth TBM paint scheme – called Sirocco, based on the creativity of French designer Alexandre Echasseriau – has been added to the aircraft’s style customization possibilities.

The TBM 960 has been certified by EASA (the European Union Aviation Safety Agency); with certification by the U.S. FAA (Federal Aviation Administration) currently underway. Deliveries will begin in the first half of 2022.

With the new aircraft’s launch, Daher’s TBM family is now offered in two versions: the TBM 960 and TBM 910.

The Aunt Betty Directive: PFD Failures
ByCharles McDougal April 8, 2015April 15, 2015

Glass panel displays, ballistic parachute aircraft recovery systems, portable tablet computers enabling paperless cockpits, and widely available three axis autopilot systems have changed the way we fly, the way we train, and the way we are expected to perform on check rides. Our training and testing paradigms have tried to stay in synch, yet always seem to be catching up to the latest levels of technology.

This is very apparent when we instructors are preparing a student for an FAA practical test. When training aircraft had no autopilots, no GPS, and certainly no parachutes, the general philosophy was that during training, the student should have the lowest level of technology available. This was also the expectation on the check ride. This theory has changed over the years and now the Practical Test Standards require that an applicant integrate all available technology while demonstrating mastery of his or her aircraft. This raises numerous questions from instructors and students about what technology will be available for each task.

One example of this dilemma is found when contemplating an instrument airplane practical test in a Cirrus SR20/SR22. The test requires the task “Instrument Approach without Primary Flight Display”, which has taken the place of what was the partial panel approach, accomplished without use of gyroscopic heading and attitude indicators. In the Cirrus, the standby attitude indicator, standby airspeed, and standby altimeter are available, as is the Multi-Function Display. Guidance from the FAA has us shooting a GPS approach using the moving map display on the MFD after disabling the PFD. Those of us who trained and tested in steam gauge aircraft think that this task should be fairly easy. With a fully functional Attitude Indicator and a nice big moving map display showing our course, a reasonably competent instrument pilot should have little trouble adapting to this setup and flying a good approach.

But, in the Cirrus specifically, and perhaps in other aircraft as well, another question comes up. Can the applicant use the autopilot (which still works just fine after a display failure) during the approach without the PFD? A rather famous DPE who writes for a national magazine says “yes”, opining that not to allow its use would be introducing simultaneous multiple systems failures, which is strictly forbidden in the minds of some. If we follow this logic, we would not test simulated engine failure emergencies in these aircraft either, because to do so would imply failure of not only the engine, but the CAPS parachute system as well. In my former role as a pilot examiner, I always said no, that the approach should be hand flown. Here is my logic.

I was amazed that flight instructors and examiners would accept the substitution of autopilot technology for the skill required to fly an approach without the PFD. I would argue that the intent and the well described emphasis of the PTS is that the applicant must demonstrate the ability to control the airplane after a loss of the primary flight display, not observe and monitor the autopilot controlling the airplane! This argument was generally unpersuasive, so I approached from a different point of view, that of a concerned family member.

“Aunt Betty” represents a future passenger flying with the soon to be rated instrument pilot. Here is the question posed to Aunt Betty: “When we train and test pilots for instrument proficiency, we require them to demonstrate the ability to safely and skillfully fly the airplane without their primary instruments. Now, Betty, in this airplane, we can test this task in one of two ways. We would like your input on which way you would prefer, seeing as you will be a frequent passenger with your nephew. We can either have the pilot (might be your son, brother, husband, or nephew) demonstrate that he can fly the airplane by hand without the PFD, which does require a little more skill and a slightly different technique, or, we can require the pilot to perform this task using the autopilot so that the pilot basically monitors the airplane flying itself on the approach.

“Now, Aunt Betty, a pilot allowed to use the autopilot system on this approach may not have the skill or technique to fly the approach by hand in the clouds should the autopilot shut down due to turbulence or mechanical failure. Should this happen to a pilot without the skill and practice normally required, the odds of a fatal accident occurring would be quite high.

“So what do you think, Aunt Betty? Would you feel more comfortable flying with this fellow if he has demonstrated mastery of the aircraft (sans PFD) without the autopilot or only with its assistance?”

This leads us to a larger discussion about the use of other technology, iPad, GPS moving map, and more. If technology is used as a replacement for pilot proficiency during training and testing, we end up with less skillful, less competent and ultimately less safe pilots. But, if we require that our students demonstrate mastery with the lowest available level of automation and technology (which, by the way, implies excellent fundamental aircraft control skills) then, when technology is added into the equation, we have a safer pilot.

Technology can be a value added safety multiplier, or it can be a crutch needed to make up for lack of fundamental and advanced skills. Crutch or Safety Multiplier, which one will you choose? I know which one Aunt Betty prefers.

Winter Ops
ByAndrew Robinson August 10, 2015August 19, 2015

It’s summertime and the weather is hot! Over this dry, sunny season, winter flying is probably the last thing on your mind. However, now is the perfect time to start getting things in place for winter and that includes having a plan for taking care of your airplane.

Why are preparations for winter ops needed in the first place? Cold weather, especially during the engine start and warm up period, can be very damaging to your engine if precautions aren’t taken to ensure that safe temperatures exist inside the engine before you turn the key. I always thought that the biggest problem associated with cold weather was engine oil. The logic is since cold oil is thicker and less viscous as the temperature drops, it is not able to circulate quickly throughout the engine to provide proper lubrication upon starting.

While cold oil may be a factor, the introduction of multiviscocity oils has greatly reduced that issue. The real problem is created by the different ways that various parts of the engine respond to heat. Because aluminum expands more quickly when heated than steel does, the pistons (made of aluminum) expand more quickly than the cylinders (made of steel). This can lead to scuffing on the sides of the cylinder barrel. In the same way, differential heating can reduce clearances which are designed to provide cooling oil to bearings and other vital engine parts, thereby causing damage which greatly reduces the life of the engine.

So how cold is TOO cold? Unfortunately, that is a difficult question to answer. Because there is so much variation between engines, airplanes, and environments, there really isn’t any one specific answer. An older, more worn out engine may actually be less susceptible to cold weather damage than a newer, tighter engine because its internal clearances are probably not as tight as they were a few thousand hours ago. I have heard of some people who preheat their airplanes anytime the temperature falls below about 40 degrees. For us northerners, this seems excessive. On our E33A Bonanza which has a Continental IO520, we generally preheat the airplane when it is cold soaked in temperatures below freezing (32° F).

Here are a few of the best ways to get your machine ready for a cold weather flight:
- Heated Hangar: Nothing beats a heated hangar for warming up an airplane. The warm air is evenly distributed around the engine and in the cockpit (your avionics and gyros will thank you!). The airplane will need to be in the hangar for a while in order to warm up the guts of the engine. Often, the easiest way is to have the airplane pulled in the evening before the planned departure and left overnight. Many FBOs will hangar airplanes overnight for a small fee and it is well worth the price. We almost always have our charter airplanes put into hangars overnight when on a winter trip to ensure that we don’t have any trouble when we depart the next day. This practice has the added benefit of keeping the airframe clear of any ice and snow that may accumulate before you are scheduled to leave.
- Electric Engine Heaters: Multipoint electronic heaters use heating pads that are placed around the engine in order to heat up the various components such as cylinders, the oil pan and crankcase. Most of these systems are designed to be activated by being plugged into a wall outlet with an extension cord. Preheating for a winter flight is as simple as going to the airport the night before and plugging it in. Two well known manufacturers of multipoint engine heaters are Reiff and Tanis. These systems are relatively inexpensive and can be a life saver if you regularly travel in colder climates. If an engine heater is the right choice for you, it is recommended to avoid less expensive models that heat only the oil pan.

- Covers and Blankets: If it is especially cold or you have to preheat outside, having something to insulate the cowling and keep the wind out can be very useful. Regular blankets will work long as you can secure them in place. If you have an ongoing need for additional insulation, there are companies that make custom blankets and propeller covers to fit your airplane. If you are landing and then taking off again relatively quickly, using a few blankets and cowl plugs will work nicely to keep the engine warm while it is sitting outside. In a pinch, placing a couple of powered light bulbs in the cowling overnight with insulation on top can result in sufficient temperatures for starting the engine.
Even with the multipoint electric heater, we still use a blanket while preheating to help keep everything toasty.
- Forced Air: This method is used widely by FBO’s and flight schools. Hot air is produced in a portable heater and is then pumped into the engine compartment via the openings at the front or bottom of the cowling. This method has the benefit of not requiring any additional equipment to be installed on the aircraft beforehand and can be very effective provided there is adequate time for the engine to heat completely before removal.

- Winter Baffles: When the air temperature starts to drop into the teens and lower, you may find it difficult to keep your engine temperatures warm enough in cruise flight. The problem is that the air entering the cowling inlets is so cold that it overcools the engine. The solution is to install additional baffling in the engine inlets to reduce the amount of airflow into the cowling. These additional baffles are usually just sheets of aluminum that are cut to the correct size and are bolted in and removed quickly and easily as needed. Some pilots swear by them while others complain that they can cause uneven cooling. If you have questions about winter baffling, I’d suggest talking to your mechanic about your specific airplane.
Winter flying can be extremely rewarding. After their hands thaw from preflight, a pilot is often rewarded with smooth air, improved performance and outstanding views. Just don’t forget to prepare the airplane for the cold. The preparation is often as simple as plugging in an extension cord or making a phone call to the FBO. So whether you live in the north or the south, take good care of your engine so that it can keep taking good care of you.
