Upgrading Avionics

There are many different ways to upgrade an instrument panel.  Putting in a 696 here, a JPI engine monitoring system there, even an Electronic HSI.  But, if you want to swing for the fences and get a serious upgrade, you have to go for a complete glass instrument panel.  For good measure, you might as well throw in a touch screen GPS while you are at it.

Which panel to go with?  There are two mainstream options (Garmin and Aspen) and a handful of other companies that make glass panel replacements (Avidyne being one, King for a short period of time at the end of the last decade being another with the KFD 840).  Around 2010, there were a lot of companies trying to get into the glass panel retrofit game, but many of the products didn’t gain a whole lot of popularity, leaving Garmin and Aspen at the top of the heap.

What about the touch screen GPS market?  Garmin has this pretty much cornered as well, with Avidyne and King just getting into the game.  The gap between Garmin’s GTN series and Avidyne and King is pretty wide.

Garmin GTN Series

The answer is pretty easy when it comes to the GPS (go with Garmin!), but not so easy when it comes to the panel.  The G500 and the Aspen Evolution series are both excellent interfaces with strong reliability, so which one do you go with?  Feature-wise, both have a lot of the same features: traffic, weather, terrain, synthetic vision, to name a few.  The presentation for each feature is a little different between the two interfaces.  It just depends on what you like better.

The nice thing about the Aspen system is you can go glass, but you have options on how much glass you want:  1 screen, 2 screens, or 3 screens?  With the single screen PFD, you have all your instrumentation, traffic, weather, and optional synthetic vision.  You don’t need the synthetic vision for the traffic and weather, as it shows up behind your HSI.  It is an honest to goodness glass panel retrofit.

When you decide to upgrade to 2 screens, this is where Aspen has a leg up.  The second screen is a completely redundant PFD and, if you get the 2 hour emergency backup battery installed, acts as the backup instrumentation to the main PFD.  This means you can take out the old steam gauge standby instruments.  This helps clean the panel up.

I personally don’t see the need for 3 screens, but maybe there is someone out there who needs it.

One selling point that Aspen has over Garmin is the wide variety of autopilots and GPS units that Aspen units are compatible with.  The G500 is only compatible with King autopilots, it’s own GFC 700 autopilot (which would be a retrofit), some Collins autopilots, and the Century 21, 31, 41, and 2000.  This does cover a wide array of autopilots, but it keeps some on the outside.  Aspen, on the other hand, is compatible with most autopilots on the market.

Finally, let’s talk price.  Going with an Aspen EFD 1000 PFD (this is the single screen Aspen) will run you somewhere in the area of $12,000.  The price will vary based on the shop and the airplane.  When you want to add a screen, it’s an additional $6,000.  This is for the base, so if you want to add weather or synthetic vision, it’ll run you a little more.

The Garmin G500 comes in around $20,000, again depending on the shop and the airplane.  The screens are bigger on the G500, which is kind of nice, and you are buying a Garmin product, which has a fabulous track record in the aviation industry.

Decisions, decisions.  There really is no wrong answer here.  Both are excellent products with very good track records.  Both have really nice features and don’t hardly fail.  Really, the choice comes down to what you want.

  • Removing a Hold on Foreflight Approach

    I’m a big fan of having my Foreflight map always match up exactly with the way I am flying. Having a Flight Stream in the airplane helps a lot with that as it always prompts me to load the new flight plan from the GPS into my Foreflight map. When I load an approach in the GPS flight plan, Foreflight will put it into my Foreflight flight plan via the Flight Stream.

    The problem I run into on Foreflight is when there is a published hold at the Initial Approach Fix (IAF), but ATC has told me to fly the straight in approach and skip the hold. Up until recently, I didn’t think there was a way to set up a straight in approach on Foreflight, so I just settled for the hold staying on there.

    Not anymore! There is a simple trick that I discovered that allows you to remove the hold from the Foreflight flight plan. Here’s how to do it.

    Load the Approach

    The first step is still to load the approach into your Foreflight flight plan on the Map page. In this scenario, we are flying from KAQO, the Llano Airport, to KHYI, the San Marcos Airport. Austin Approach has told us to expect the straight in RNAV 17 KHYI via PUKIY. So, on Foreflight, we have KAQO and KHYI in our flight plan. Then, I tap the Procedures button on the upper right hand corner of the screen. I then tap Approach, then RNAV 17 KHYI. Then I select my transition.

    The options given are either PUKIY with the hold, seen below;

    Or Vectors to Final, which lines me up inside of PUKIY. Neither of these are what I want.

    But, to get this to work, I select PUKIY, then tap add to route. Now we have our approach loaded into our flight plan.

    Removing the Hold

    The RNAV 17 is now in the Foreflight flight plan, but the hold is displayed at PUKIY. To remove the hold, the first step is to tap the approach in green and a menu pops up.

    The 7th option down is “Remove Hold in lieu of PT.” Eureka! Tap that, then the approach is displayed without the hold. Houston, we have success! It even says “NoPT” in the flight plan.

  • The Dual Garmin G5 Glass Panel Solution

    What’s the most cost effective glass panel retrofit?  There are several options out there (and it seems like more coming each Sun ‘N’ Fun or Osh Kosh event), but the consensus is the Aspen EFD 1000 or 1500, right?  At $12,000 installed, it’s about $8,000-$10,000 cheaper than the Garmin G500 (though you can make the argument that when you add a second screen and SVT to the Aspen, the price is about the same).

    I am here to blow your mind.  What if you could get a glass panel retrofit that is a complete AHRS system with airspeed and altitude, plus a slaved HSI that auto slews to your GPS and a 4 hour backup battery so you can throw your steam attitude indicator away, for only $4,600, plus installation?

    I am not crazy.

    The Garmin G5 debuted last year when the FAA relaxed it’s regulations to allow more experimental avionics into certified airplanes.  The single G5 was a big hit.  The 3.5 inch screen fit nicely into the hole that the traditional attitude indicator left, giving pilots a glass attitude, airspeed and altimeter options for less than $2,500.

    In March, Garmin brought out the HSI version of the G5.  Equipped with a low cost magnetometer, the DG/HSI version is a complete replacement for the traditional DG/HSI.  The unit also displays ground speed and distance (received from the GPS information), while auto-slewing to the GPS flight plan, so the CDI needle will move on it’s own, eliminating the annoying need for the pilot to set the course on the HSI (and ridding the GPS of the message that pops up reminding the pilot to set the course).

    The dual units provide a complete backup Attitude in the case of a display failure.  The reversionary mode you get with the Garmin G1000 and the Garmin G500 is also present in the dual G5s.  This eliminates the need for a backup steam gauge attitude indicator, freeing up panel space for an engine monitor or some other toy.  The G5 units can also be equipped with 4 hour backup batteries in case of electrical failure.

    The price for the dual G5 setup is very reasonable at just under $4,600 plus installation (which, according to Garmin, should be pretty simple as the units act as plug and play instruments).  The AHRS unit is available stand alone for under $2,200 while the DG/HSI unit standalone runs just under $2,600.

  • Cirrus CAPS Saves Lives Again

    In July, a Cirrus SR22 suffered an engine failure in Houston after departing KIAH.  The CAPS system was deployed and the airplane came to rest in a neighborhood on the north side of Houston.  This makes CAPS save number 53 for Cirrus and no fatalities.  The initial NTSB report is below.

    N422PB CAPS

    14 CFR Part 91: General Aviation
    Accident occurred Tuesday, July 07, 2015 in Houston, TX
    Aircraft: CIRRUS DESIGN CORP SR22, registration: N422PB
    Injuries: 2 Minor.
    This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

    On July 7, 2015, about 1137 central daylight time, a Cirrus SR-22 single-engine airplane, N422PB, descended under the canopy of the cirrus airframe parachute system (CAPS) and landed in a residential neighborhood at Houston, Texas. The pilot and passenger sustained minor injuries, and the airplane was substantially damaged. The airplane was registered to and operated by AIRCCS, LLC; Humble, Texas, as a 14 Code of Federal Regulations Part 91 business flight. Day visual meteorological conditions (VMC) prevailed and a flight plan had not been filed. The airplane departed George Bush Intercontinental/Houston Airport (IAH), Houston, Texas, at 1133 and was destined for Austin Bergstrom International Airport (AUS), Austin, Texas.

    The pilot reported that during initial climb, he noticed the engine temperatures began increasing and he reduced power in an attempt to lower the engine temperatures. When the airplane was about 900 feet above ground level (agl) the engine began detonating, and soon after there was a complete loss of engine power. With no suitable forced landing areas the pilot deployed the CAPS ballistic parachute system and the airplane impacted terrain and came to rest upright next to a residence.

    An initial on-scene wreckage examination showed there was adequate fuel on-board. At the facility where the airplane had most recently been refueled, refueling unit records and a review of security camera video showed that the airplane had been refueled with aviation gasoline and not with jet fuel. Postaccident fuel quality checks of that fuel facility were satisfactory.

    The wreckage was moved to a different location and will be further examined. Several avionics components containing non-volatile memory (NVM), including engine performance data, will then be removed from the wreckage for examination and an extraction of useful data is expected.

    At 1053 the Automated Surface Observation System at IAH reported wind from 160 degrees at 15 knots gusting to 20 knots, visibility 10 miles, scattered clouds at 3,000 feet agl, broken clouds at 25,000 feet agl, temperature 31 degrees Celsius (C), dew point 24 degrees C, and an altimeter setting of 30.03 inches of Mercury.

  • A Sad Reminder

    It was a rainy Thursday afternoon and I was eating lunch with my family when my phone rang. My wife and I had just been discussing how miserable the weather was, so it was only natural that about 30 minutes later I was soaking wet and sitting in one of our Aerostars getting ready to take off for Ohio. I didn’t have much information about who I would be flying, or why, but I knew that I was going to pick someone up to fly them home; something about a missing airplane. So off I went into the muck. My biggest concern at that point being whether or not my clothes would ever dry out.

    I arrived uneventfully and walked happily into the FBO, but found myself quickly in a very different atmosphere. It turned out I had two passengers to pick up, a husband and wife, and they had arrived at the FBO before me. As I walked in the door, the wife received a phone call. The person on the phone told her that search teams had found her father’s airplane crashed in the woods and that he was dead. I learned the rest of the details quickly and it was hard to stomach.

    She was travelling home that day to be with family until they were able to locate her father. She was pregnant with her first baby and was in her third trimester. The baby was to be her dad’s first grandchild. He’d owned a Lake Amphibian for years and had stayed at home to work while his wife was out of town. He was last seen leaving work on Tuesday of that week and was reported missing on Thursday by his co-workers. Airport security footage showed him pulling the airplane out and taking off at 20:48 (after sunset) on Tuesday night.

    After a few minutes we loaded the Aerostar and took off. It was the saddest flight I’ve ever done. Understandably, my passanger sobbed on and off from the time she got off the phone until we landed a couple of hours later. The weather seemed appropriate as we flew along through the rain and were greeted at our destination by a grief stricken family and a few reporters.

    I said a sad goodbye and left, but I couldn’t help but think about their situation. It really hit close to home with me as it was easy to draw parallels between my family and theirs: she was very close in age to me and pregnant with her first child. My wife and I were new parents. Her dad had owned his airplane for about the same length of time that my dad has owned his Bonanza. Additionally, it isn’t uncommon for my parents to go a couple days without being able to reach each other because they both travel.

    A Lake 250, the same type of aircraft involved in the accident.

    But what happened..?

    In the time since the accident, the NTSB has published their findings and unfortunately, it makes the situation sadder. It was completely avoidable.

    Airport security cameras showed that after removing the airplane from the hangar, the pilot did not complete a preflight inspection or even a walkaround of any kind. He simply climbed in and left. The investigators were unable to find any traces or odor of fuel in the wreckage, nor any mechanical abnormalities with the airplane. In fact, according to the report, the engine was put on a test stand and ran perfectly. It would seem that the pilot simply never checked the fuel quantity and took off. The airport cameras captured the take off and a bright flash about 30 seconds after the aircraft departed.

    Here is an excerpt from the report:

    The National Transportation Safety Board determines the probable cause(s) of this accident as follows:  The pilot’s attempted 180-degree return to the runway immediately after takeoff in dark night conditions, which resulted in collision with trees and terrain. Also causal was the pilot’s inadequate preflight inspection, which resulted in a takeoff with little-to-no fuel on board the airplane.

    Interestingly, the report also details their ability to use logbook information and fuel receipts to show the airplane was taken on a long cross country on its last flight and likely not fueled again.
    Another thing which stuck out in my mind upon learning the details of the crash was how important it is to let someone know when you’re going flying. Having another person know roughly when a flight is leaving, where it’s going and and when to expect it back could potentially save the lives of the people on board. In the case of this accident, the pilot didn’t alert anyone that he was going flying and therefore, no one realized he was missing for 2 days.

    From reading the NTSB report I don’t get the impression that he survived the crash, but I can’t help thinking about the possibility that he, or others in similar circumstances, could survive a crash and then die from their injuries because no one knew to look for them. When I flew charter, we weren’t legally allowed to take off VFR without letting someone at the company know the details of the flight. I’ve adopted this as my personal policy as well. One text message could be the difference between being rescued or not.

    Finally, every pilot should ensure that a proper walk around is completed! It’s easy to assume everything is okay with an airplane, especially one that no one else has access too. In addition to a thorough preflight, I like to walk all the way around the airplane and visual check fuel caps, doors, chocks, ropes, etc., immediately before getting in to ensure that everything is ready. I know a couple of pilots who have taken off with various panels and compartments open simply because they got distracted during their walk around and never closed them. (A good policy is to never walk away and leave something open). Perhaps even more mind boggling is that he apparently didn’t look at the fuel gauges after start up and before take off. I also have to wonder how much fuel he had remaining upon completion of the previous flight.

    “Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect” is likely a familiar quote to just about every pilot. It is often written on a poster with a picture of an old timey bi-plane hanging out of a tree, but I think that it is absolutely on point. Carelessness in the preflight and neglecting basic pilot responsibilities (in this case fuel planning) cost this father his life and his opportunity to meet his first grandchild.

    I know this article is a real downer, but it’s supposed to be. Its tragic that accidents take place which are completely avoidable. Obviously this case was beyond the normal realm of carelessness and neglect, but, we as pilots need to be extremely careful not to get so comfortable with an airplane that we stop doing the things which are so basic and important to safety. One of my professors in school used to say “aviation is fun, but it plays for keeps,” which is an effective way to remind myself how important it is to do it right.

    *Out of respect to the family, I have not included any specific names, tail numbers or airports in this article.

  • Pitch + Power = Performance

    My first chief flight instructor had an addage he would impart to his flight instructors when we began working at that flight school. “Pitch + Power = Performance” he would tell us. Then he’d glare at us and follow up with, “nobody teaches that right, so make sure your students know it.”

    Now, having been a CFI for seven years, I would tend to agree with him. I have moved on from doing mostly primary training to transition training. Transition training is taking someone who is already a pilot and teaching them how to fly a different type of airplane. In jets, you get a type rating. In piston engine airplanes, there is no FAA requirement to go through any type of extra training as long as you are rated in category and class (eg. single engine piston). But, insurance companies know that Mr. Fresh Private Pilot can’t just hop from a Cessna 172 into a Cirrus SR22 or a Bonanza, so they require transition training before insuring those pilots.

    What did my chief instructor mean when he imparted his wisdom? He was speaking about a particular phase of flight, the final approach phase, regardless of whether it’s a VFR approach or an IFR approach. The pitch of the airplane and the power setting of the airplane have to be utilized together to achieve the proper speed and descent rate (performance).

    VFR

    On the final approach leg of a VFR pattern, most piston engine aircraft are configured with landing gear down and flaps down in the landing position. This puts the airplane on the back side of the power curve in the region of reverse command. In the region of positive command, in cruise, for example, the more power you add, the faster you are going to go and, if you pitch up, you will go up and you pitch down, you will go down. But, they work together (if you point the nose down, you will accelerate unless you reduce the power); remember, Pitch + Power = Performance.

    diamond-landing

    In the region of reverse command, the pitch controls the airspeed and the power controls your rate of descent, but, again, they work together. Let’s say the airplane is 5 knots above it’s approach speed on final. Initially, the pilot will need to pitch up slightly to bleed off that airspeed. The airplane will want to climb, so as he is pitching up, he’ll need to make a slight power reduction to stay on glide slope.

    Alternatively, let’s say the airplane is high, but is on speed. The pilot will make a power reduction to descend to the glide path, but he’ll also need to pitch down to maintain the proper airspeed.

    What you don’t want to do is this: if the airplane is high on final, don’t push the nose down to try and get down. This does cause the airplane to lose altitude quickly, but the airspeed increases quickly. With a higher airspeed, the airplane has a lot more energy to dissipate when it gets to the runway, meaning you’ll float longer which can lead to forcing the airplane down or using up too much runway and not being able to get the airplane stopped in time.

    IFR

    On an instrument approach, you are on the front side of the power curve. When trying to stay on glide slope, the power is controlling the speed of the airplane and the pitch is keeping the airplane on glide slope. This can be a little bit confusing for VFR pilots transitioning to instrument approaches as they are not used to being on the front side of the power curve.

    Keeping in mind that Pitch + Power = Performance, let’s put the airplane above the glide slope on an ILS approach. In order to get down to the glide slope, the pitch needs to be lowered as much as needed (it’s always better to pick a pitch attitude to fly and see if it is working to bring the glide slope back to center. If it doesn’t work, pick a new one. Don’t just push the nose down until the glide slope moves) and the power needs to be reduced to maintain airspeed (again, pick a specific power setting). Once the glide slope centers, then the pitch will be raised slightly and the power will need to be increased to hold glide slope and speed respectively.
