So the Word became human and made his home among us. He was full of unfailing love and faithfulness. And we have seen his glory, the glory of the Father’s one and only Son (John 1:14).
From the Texas Top Aviation family (Hank, Kelsey, Everett, Cooper, and Cord) to your family, we wish you a Merry Christmas! We are thankful for how the Lord has blessed us this year. We pray for blessings on your family this coming year.
The FAA defines personal minimums “as an individual pilot’s set of procedures, rules, criteria, and guidelines for deciding whether and under what conditions to operate (or continue operating) in the National Airspace System.” Have you actually given thought as to why we choose the personal minimums we do? From the beginning of initial pilot training, weather minimums were established for day-to-day training and during solo flight. I didn’t realize it at first, but I later learned these limits were not just an insurance mandate, but these minimums were set at the time to safely operate an aircraft based on my “then” current experience.
So here’s the question: what are your personal minimums and WHY do YOU have them? Do you ever lower or raise your minimums? Are your minimums based solely on your overall experience level or do they take into account other variables such as advanced avionics? For pilots that fly multiple aircraft like I do, can and do your minimums change in regard to category or type of aircraft you are flying? It’s a judgment decision on how you chose your minimums. However, it’s important that time is taken before you strap into the cockpit for each flight to critically think about the different risk factors and variables which may affect your decision for the minimums you choose.
To guide us, let’s try briefly apply the FAA’s Personal Minimums Checklist to see how risk factors might shape what personal minimums or decisions we make for the day. Remember, just because you have been flying with a certain set of minimums one day, doesn’t mean you can’t adjust your minimums to a higher value given an ever-changing situation.
The acronym most pilots have heard is PAVE:
Pilot– We all should be familiar with the acronym IMSAFE associated with this. It addresses variables such as Illness, Medication, Stress, Alcohol, Fatigue, and Emotion. But how do you adjust your personal minimums using this guideline? Have you ever thought about raising your minimums for a training flight if you only got 4-6 hours of sleep, instead of 8? Or if you anticipate a hard IFR flight with a long day, maybe taking a safety pilot to mitigate the chance of a mistake if you’re forecasting having to shoot an approach to your weather planning minimums.
Aircraft– Personally, this is a really important factor for me when deciding what minimums to apply. I often spend a large majority of my time asking myself; is this aircraft properly equipped for the flight? This question goes beyond just looking at the logbook for a properly equipped and legal aircraft. A professional pilot should think further. Am I flying a traditional 6-pack “steam gauge” layout, non-slaved compass card, with a separate OBS gauge for course guidance? What if the aircraft doesn’t have an auto-pilot? What if I’m flying an aircraft equipped with a dual auto-pilot, dual GPS with an integrated glass cockpit? I can comfortably say my personal minimums change depending on the equipment I have available.
A pilot should also look at his/her recency with the aircraft. For example, if you are qualified to fly both airplanes and helicopters, maybe you should choose to have higher personal minimums in one particular airframe or if you haven’t flown that airframe within 30, 60 or 90 days. This is a very important factor for the owner/pilot.
EnVironment– Most of the time, when we think of environment, we ask ourselves, is the weather legal for me to take off and, more importantly, can I conduct this flight safely? Basic flight planning should have taught us to take into consideration crosswind limits, day versus night, and the type of airspace the flight is conducted in. Thought should also be given to how you set your personal minimums in regards to the particular type of environment you might rarely encounter. Flying an approach to your minimums in the flat plains of Texas during the day is one thing, but how would you adjust your weather minimums flying to a new airport, at night, with no moon illumination, in the mountains of Colorado? Could you reduce the risk and adjust your minimums in this scenario with two pilots?
External Pressures – What external pressures are affecting your flight? Passengers, the owner, “get-there-it is”, the desire to impress someone? Although external pressures should never be a factor when conducting a flight, they almost always play a role in your decision whether to conduct the flight or not. For example, a professional pilot gets hired to do a flight and the weather is below their personal minimums. The pilot could be tempted to lower their minimums by 100 feet to take the flight for a paying customer. This scenario plays out every day across the country whether it’s a professional pilot or owner/pilot. It would be foolish not to consider this type of pressure. Always make sure you have a plan if and when you encounter this situation. Planning your flight and having a plan to deal with these potential scenarios ahead of time ensures you stick to your minimums. It can be as simple as telling your passengers, or the owner, well ahead of your flight what your personal minimums are to accept the flight, and to ensure they, or you, have a back-up plan!
Most pilots will never break a hard limitation such as an airframe cross wind limitation, or engine limit, but the chances of breaking a personal minimum are realistic. Think about the last time you went on a diet and broke your plan because you were tempted by your friends or family during an outing. Self-imposed personal minimums can be hard to enforce and we need to acknowledge this as humans. Here are a few techniques that you can use to assist in making a decision using personal minimums and help reduce the influence of external pressures.
Step 1: Sit down with your CFI/CFII and fill out a personal minimums worksheet. Filling one out by yourself is a good start but having an outside objective view will help in making sure your personal minimums are realistic. Remember, it is easy to convince ourselves that we can do something even though we have set personal minimums. Talk with other pilots to see if you have set realistic expectations.
Step 2: Preflight planning must start a few days in advanced. It can be as easy as checking what the forecast might be and looking at the projected route, near-by alternate airports, and various approaches. This can be done quickly and will give you a heads up on whether the flight can be safely conducted or not. By alerting the passengers or owner early enough, alternate plans can be developed. An extra pilot can be added, the passengers can fly commercial, bring along a CFI, or cancel the trip altogether and seek alternate transportation. The main point is the decision was made well ahead of the flight when conditions didn’t look favorable. This helps in removing external pressures and ensures you don’t go below your personal minimums.
Step 3: Never be afraid to ask for a second opinion. Part 135 operators have set procedures for conducting flights which assist the pilots in making decisions. These set procedures help remove external pressures by allowing the pilot to say, “The rules don’t allow for this, or this is how we will conduct the flight!” However, under Part 91, the pilot has to take ownership for all phases of the flight. This is where talking it out with another pilot helps with mitigating external factors and the environment. Ideally, this person should have more experience and be able to talk through the situation. For instance, if I’m flying to a new destination, I often seek the advice from another pilot who’s familiar with the area. They may have key insights into weather patterns, preferred approaches, or hazards to avoid. In certain situations, asking for another pilot’s opinion might be what influences your go/no-go decision! You’ll be amazed how much you can learn just from talking to other pilots.
Step 4: Continue to build your experience and knowledge base. Building experience requires us to push our abilities, and sometimes this may be to the limit. However, this can be done in a controlled training environment or just going out and experiencing it. Get a new license, fly regularly with a CFI/CFII, and always try and take advantage of training opportunities. For example on your next flight from point A to point B, practice hand flying an approach, do a short field landing, a quick steep turn, etc. Quality flight time is always better than quantity. Continue to challenge yourself and try not to become complacent.
Personal minimums are a tool to assist in every pilot’s aeronautical decision making process. Use your personal minimums to guide your final go/no-go decision and remember to stick to the plan. I encourage you to review the FAA’s Risk Management Handbook (FAA-H-8083-2). Appendix B has Sample Risk Management Scenarios and reviewing them will give a better understanding how to apply the techniques discussed to your everyday flying.
Pedro Vargas-Lebron is a King Air 200 and uH-60 Blackhawk Instructor pilot with the Texas Army National Guard. Pedro is a CFI/CFII/MEI both in airplanes and helicopters with over 4000 hours of flight time, half as an instructor pilot.
A Cirrus is an electric airplane. There are no vacuum pumps and therefore no vacuum driven instruments. The Klapmeier brothers did this on purpose, trying to make it a modern airplane. No vacuum systems means no vacuum pump failures, hence there is a lower likelihood of instrument failures in IMC.
What Cirrus did instead was put a lot of electricity producing and storing devices in the airplane. All SR20 and SR22s are equipped with 2 engine driven alternators and 2 backup batteries. Alternator 1 is a 28 volt alternator (the amperage varies based on whether or not you have an air conditioner) while Alternator 2 is a 28.5 volt alternator. There are 2 24 volt backup batteries, as well. Battery 1 is also used for starting.
In traditional airplanes that have 1 alternator, an alternator failure can affect a lot of things. Depending on how many electronics are in the airplane, the battery can get depleted quite quickly.
The Cirrus electrical system is quite ingenious. It’s a little bit different based on whether you have an Avidyne Cirrus or a Garmin Perspective Cirrus. I will discuss that further below.
The main goal of this article is to talk through what happens in the event of a #1 Cirrus Alternator Failure (an Alternator 2 failure actually isn’t a big deal at all, though Alt 2 is required for IFR flight), the procedure for trying to fix it, and a technique I have developed that makes the pilot’s job easier. First, let’s go through the #1 Cirrus Alternator Failure procedure.
Alternator 1 Failure
In either avionics configuration, the Cirrus Alternator Failure procedure is the same.
Check and reset the circuit breaker for Alternator 1 (Reset only once)
Cycle the Alternator 1 master switch
If Alternator 1 doesn’t come back online, leave the Alternator 1 master switch off and shed load on the battery
Avidyne Entegra
The Avidyne Entegra has 2 busses, the Main Bus and the Essential Bus. Alternator 2 isn’t set to come on until the engine RPM reaches 1700. While on the ground, Alternator 1 runs both the Main and Essential Buses. In the air, Alternator 1 runs the Main Bus and Alternator 2 runs the Essential Bus. Since Alt 2 is 28.5 volts, the higher voltage won’t allow the power from Alt 1 to cross over and run the Essential Bus. There are also 2 one-way directional diodes that prevent the voltage from Alt 2 to cross over and run the Main Bus.
Having said all that, when Alternator 1 fails, Battery 1 is now running the items on the Main Bus. There are a significant number of items on the Main Bus which causes the 24 volt battery to quickly lose it’s charge. This precipitates the need for shedding load. Items like GPS 2, the air conditioner and aircraft lights can all be turned off.
In the above scenario, Alternator 2 is running the Essential Bus still that has all the Essential items on it. Those include:
The PFD
Flight Instruments and associated Avidyne computers
Engine Instruments and associated Avidyne computers
GPS 1
Com 1
Nav 1
Autopilot
Stall Warning
Charging Battery 2
Note 2 important items that are not on the Essential Bus: the flaps and the landing light (which is very handy at night). Those two are only on the Main Bus, which Battery 1 is now powering.
Let’s further enhance our scenario. You are flying over Nevada (quite remote and not a lot of airports) at night, 30 minutes from the nearest airport when your Alt 1 fails. When you get to the airport you are planning on landing at, you want to have your flaps and your landing light, but we don’t know how long Battery 1 will last.
The solution (this is where my technique comes in): Turn off the Battery 1 master switch. This is an easy solution to ensuring you have battery power to use your flaps and landing light. Instead of going through and shedding load, simply turn off the source. You’ll still have all the above items on the Essential Bus, which is all you need to keep safely flying. Then, when you get to your landing airport, turn Battery 1 back on to utilize your flaps and landing light.
Garmin Perspective
Cirrus wired the Garmin Perspective plane a little bit differently. There are now 2 Main Buses along with the Essential Bus. Alternator 1 runs Main Bus 1, while Alternator 2 runs Main Bus 2 and the Essential Bus. Both Alternators are running all the time. The Alternator 1 Failure procedure remains the same.
The cool thing that comes along with the second Main Bus in the Perspective is the amount of items you still have available to you in the event of an Alternator 1 failure. The only items you lose will be:
Yaw Damper
Landing Light
Air Conditioner and associated components
EVS Camera
12 Volt power supply in armrest
Everything else is powered off of Alternator 2. That’s not much. The only item you really want on the above list is the landing light if you are going to be landing at night.
Follow the Alternator 1 Failure procedure, then do my technique again. Turn off Battery 1 to save the battery power in order to use the landing light when needed.
Cirrus did a great job creating an all electric airplane with plenty of backups in case something fails. I focused mainly on the Alternator 1 failure here. If Alternator 2 fails, the system is wired for Alternator 1 to run everything while still charging Battery 1 and 2. No big deal.
In my experience, turning off Battery 1 to conserve battery power is just a simpler solution when shedding load in the event of a Cirrus Alternator Failure.
The Angelina County Airport in Lufkin, TX (KLFK) will be hosting the Angelina County Airfest on Saturday, October 10th. The airport will open up at 9am.
Prepare for a day of food, fun, and some great performances. There will be warbirds and many other classic airplanes on display, not too mention a number of aerobatic performances as the day goes on.
There are multiple ways to save money during the aircraft buying process. To start, since you are buying an airplane, you have some means of positive income in order to afford an airplane. Airplanes come in all different shapes and sizes and usually, an airplane can be found to fit almost any budget, whether is a $20,000 Texas Taildragger all the way up to a multi-million dollar jet.
One way is to stay within your budget. There will always be a shinier, newer, lower time airplane that is just above where you set your budget at. Don’t reach for it! There is a reason you set your budget where you did.
Another way is to shop around and get multiple insurance quotes. Your agent is in charge of engaging underwriters who are going to evaluate you and your airplane as risks, then price a policy accordingly. With most airplanes, you should get multiple quotes to see what fits you best. Beware though, because sometimes, you can get a lower rate, but it will require more training, so you end up shelling out more money in the long run. If you find a policy you like, but the training seems skewed or the liability isn’t high enough, you can always have your agent ask the underwriter to modify the quote. You are still in charge.
Finally, if you evaluate your mission and see that your budget can’t afford an airplane that carries enough or goes fast enough, look into taking on a partner or two to help with costs. Be thorough in vetting your potential partners as a good partnership is worth it’s weight in gold, but a bad one is downright unpleasant and often times hard to get out of. Find pilots who have the same mindset & personality you do and treat their stuff the same way you do. Try to take a ride in their car or go to their house, then you’ll see what kind of shape they will keep the airplane in.
The best way to cost yourself more money in the aircraft buying process?
Don’t do a pre-buy inspection.
A pre-buy inspection takes place after negotiations and once a Purchase Agreement is in place. You are pretty much set on the airplane, you just want a third party mechanic who is knowledgeable on that make and model of airplane (and this is a very important point) to go over it and make sure that it is sound from a mechanical standpoint. The buyer, you, want someone who has never had an association with the seller since the mechanic will be your representative in the process and you want him answering to you.
If you have used a broker or a buyer’s agent, that person should have already gone through the logbooks for you, so you’ll have a basic idea of the history of the airplane. However, knowledgeable mechanics find things all the time that turn out to be the responsibility of the seller to repair since it happened on their watch. Without a pre-buy, you would end up having to pay for that in the not to distant future.
Here is an example of where not doing a pre-buy can cost a lot of money.
An owner bought a late ’70s model Citation ISP, one of the very first Citations ever made. It had been based in Florida (salt & humidity + aircraft don’t mix well) for a while. The buyer didn’t use a broker, but thankfully had someone look through the maintenance history of the airplane. Since it was so old, the logbook reviewer didn’t have time to do anything but a basic overview, but he gave the thumbs up to the buyer.
The buyer decided he just wanted a boroscope inspection and the seller’s mechanics to look over the airplane. Remember what I said before about a third party mechanic? Well, these mechanics didn’t do a very thorough job. When the buyer took delivery of the plane, after about 10 hours of flying, he already had an $18,000-$25,000 maintenance bill.
You may say, well that’s a jet. Jet’s have specialized maintenance and need a more extensive pre-buy inspection.
On the contrary, in my 8 years in the training business, I have seen Cirrus, Piper PA46s, Bonanzas and several other piston engine airplanes that either didn’t have a pre-buy done or the pre-buy was done by someone who didn’t know that airframe. Lo and behold, things started breaking and adding up very quickly that would have been discovered on a good pre-buy inspection.
Don’t skip on the pre-buy inspection. They usually run a few thousand dollars, but save tons of money in the long run.
As was the case with the Class B Airspace around Houston several months ago, the Class B Dallas airspace has been overhauled as well. These changes were implemented at the last database update on September 18th. If you’ll be flying into any of the Dallas airspace airports IFR, make sure you have current charts and your GPS databases are updated.
According to AOPA, 14 SIDs and STARs were deleted, a number of new procedures were added, and changes were made to most of the other remaining procedures. The new procedures in the Dallas airspace consist mainly of RNAV procedures for turboprops and jets, so most GA aircraft won’t be affected by those. The legacy procedures that remained in place over went changes, including new frequencies, so piston aircraft going into the Dallas airspace are still affected.
From AOPA, departures from Dallas Love (KDAL) that file their flight plan with special equipment /G in their flight plan will automatically be given an RNAV departure procedure. This does not appear to affect piston aircraft as all the new RNAV SIDs in the Dallas airspace are for turboprops or turbojets.
The reason for the changes to the Dallas airspace? Similar to the changes in Houston, these airspace changes are meant to streamline departures and arrivals in the Dallas airspace area, reduce controller workload, and give continuous descent angles for arriving high altitude traffic.
Don’t be surprised the next time you are in the Dallas airspace area if you receive a clearance that states: “Descend via the arrival.” In that case, just check the chart and aim for the appropriate altitudes at the appropriate fixes. As we move closer to the ADS-B requirement, I believe we will see more and more of these terminal procedure overhauls, so be prepared and keep those charts and databases up to date.
It’s winter time, so that means winter weather for the aviation community. For single engine piston pilots, that means dealing with icing conditions. For us Texan flyers, ice only presents an issue for maybe a week out of the year (the exception being for those Panhandle residents!), but it’s nice to have some protection.
Most single engine pistons do not come with ice protection from the factory and, of those that do, most are not Flight Into Known Icing (FIKI) approved. The systems are “get out of jail” systems that can reduce the amount of ice you pick up if you accidentally get into icing conditions and you are on your way out. The Cirrus SR22 line of aircraft has had the TKS system option since 2006, with the new FIKI system being available since 2010. The Cessna TTx has a FIKI option that was debuted in 2014.
The above mentioned airplanes use TKS systems. There are a handful of single engine pistons that use boots that are FIKI certified: the Piper PA46 line (Malibu, Mirage, and Matrix) and the Cessna P210 and T210 line (though not all are equipped with boots).
If you find yourself flying into wintry conditions often and want some protection for your clean wing airplane, there are some aftermarket options for a lot of airplanes now. Do note that all these systems do come with a pretty hefty price tag, but can be worth it if you fly into icing a good bit.
CAV Ice Protection TKS Systems
CAV Ice Protection is a TKS system outfitter. What is TKS fluid? According to Flying Magazine:
“TKS systems dispense an ethylene glycol-based fluid with a freezing point below minus 70 degrees F through porous titanium panels attached to the leading edge of the wing and empennage. The fluid is released through thousands of the panels’ laser-drilled holes, which are not much larger than the size of a human hair. As air flows over the wing and empennage, it disperses the fluid, coating the surfaces, and preventing the formation and adherence of ice.”
The advantages of a TKS system are the whole entire wing gets coated to get rid of any extra ice that adheres to the top or bottom of the wing surface. The disadvantage is there is only a finite amount of fluid, so when it runs out, you don’t have any more protection. The fluid also adds extra weight agains the useful load of the airplane.
CAV Offers a Basic TKS system for the following single engine piston aircraft:
Beech Bonanza
Cessna 182, 206, 210, 350, & 400
Columbia 350 & 400
Piper PA32
Mooney M20
CAV Offers a full FIKI System for the following single engine piston aircraft:
Ice Shield is another after market de-ice option. Ice Shield makes boots for wing leading edges. The advantage of boots is they activate instantaneously, getting rid of ice where it builds up first, on the wing leading edge. No running out of fluid and only the added weight of the system. Ice Shield also offers heated windscreens for several the Piper Saratoga line and the A36, B36, and G36 Bonanza line.
Ice Shield has boots for the following single engine piston aircraft:
One other company, Kelly Aerospace, makes an electric leading edge de-icer called the ThermaWing for the Cessna/Columbia 350/400 line. You can read a review of the ThermaWing here, or check out Kelly Aerospace’s website.
