Texas Top Aviation has added a new member to our instructing team. Stephanie Mertz was hired in March 2019 and will be specializing in G1000 & Instrument instruction.
Stephanie graduated from LeTourneau University in Longview, Texas with a degree in Aeronautical Science, earning her commercial single and multi ratings while there. She began her aviation career in Ontario, California flying a Pilatus PC-12 for charter and medical trips. While operating the PC-12, she gained valuable experience flying all over the US and Mexico.
In 2013, Stephanie moved back to East Texas with her husband where she worked as a contract pilot flying a variety of Citations as well as a Falcon 10. A few years later, she became involved in her local Ninety-Nines chapter and joined their mentorship program.
After earning her CFI, CFII, and MEI, Stephanie returned to her alma mater to pass on her flying passions to college students through flight instructing. After a year of teaching at LeTourneau, she and her husband, with their first baby in tow, moved to the Austin area. Now she is instructing with Texas Top Aviation while acting as a mentor for other women working on achieving their flying dreams.
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.
The Garmin G500
The Aspen EFD 2500
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.
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.

On the evening of November 3rd, 2015, I was returning to my home airport of Lancaster from Pittsburgh in my company’s Aerostar, after being out on charter all day. It was dark out as I entered the traffic pattern at Lancaster. After an uneventful approach, I was cleared to land behind a Mooney. The spacing looked good as I turned final, but, as I was nearing the threshold, I started to become concerned that the Mooney wouldn’t be clear of the runway in time for me to land. At that moment, over the radio I heard an uncomfortable transmission from the Mooney pilot: “Tower, Mooney ABC has landed gear up.”
It took the tower controller a minute to grasp what was going on, and I was on about a 1-2 mile final when I was instructed to go around. Thankfully, the Mooney came to a stop in such a position that I was able to use the other intersecting runway, and was on the ground only a few minutes later. I can assure you, however, that I’ve never checked my “3 green” so many times in one traffic pattern as after that incident. Thankfully, no one was hurt, but there sure was an impressive amount of emergency equipment on the runway as I taxied back to my hangar.
In aviation, there’s a saying that goes: “There are two types of pilots. Those who have landed with their gear up, and those that will.” I don’t like that saying. The potential of a gear up landing (as a result of pilot error) is something that has always been a risk that I have worked hard to avoid. Not only is a gear up landing embarrassing; but it’s also an extremely expensive black mark on any pilot’s career.
Not a good day. (Photo credit: http://www.newsday.com/long-island/suffolk/plane-lands-at-republic-with-no-wheels-1.2735131)
According to a July 2006, article in Aviation Consumer, the estimated cost of repairs following a gear up landing for an A-36 Bonanza would be about $27,000 and about 3 weeks of down time. 25 years ago, even my beloved E33 Bonanza was the victim of a gear up landing. While it was neither me nor my dad flying our airplane that day, the event stays in its history and reduces its value should the time ever come to sell it.
That incident in 1990 resulted in approximately $25,000-30,000 in repairs. The cause of the incident was classic: the pilot put the gear down at the normal time, but then had his downwind extended by tower. He brought the gear back up to fly the longer downwind, but forgot to put it back down later when he was cleared to land. Like many pilots, he had a set routine time when he normally put the gear down, and when his routine was changed, he didn’t remember to lower the gear once more.
Unfortunately, no matter what experience level one may be at, no pilot is immune to the possibility of such a mistake. The following are 5 tips that I have learned in my time flying that have helped myself and others minimize the chance of a gear-up landing occurring:
Know your aircraft systems: What are the operating perimeters on your airplane’s gear warning system? Most airplanes have a designated speed or power setting at which the gear warning horn will sound in the event that the gear isn’t down and locked. In the Aerostar that I was flying, the gear horn was supposed to come on at 15” of manifold pressure with the gear up, but in practice, it didn’t come on until much lower than that. It has since been adjusted, but at the time it was important for me to know that if I had left the gear up, the horn wouldn’t have sounded in a timely enough manner for me to go around, much less lower it prior to touchdown. Most likely it would have just added to the noise of metal on concrete as I pulled the power all the way back in the landing flare.
Don’t override gear-up warning systems: They were put there for a reason! Even if you’re out doing maneuvers and the horn is blasting in your ear for half an hour, resist the temptation to simply pull the circuit breaker or push the warning silencer to make it shut up. If a pilot disables the gear-up warning horn and then later forgets to put the gear down on landing, he or she will have a much worse headache on their hands than the one that the horn would have given them.
Use your checklists and memory items: It doesn’t matter how much a pilot knows about his or her airplane, or the procedures for it. Distractions happen. Mistakes Happen. Always consult the checklist for confirmation that you’ve accomplished all the essential tasks before landing. Additionally, if you haven’t already, work on developing call outs which you perform out loud regardless of whether you are alone in the airplane or not. Whenever I’m landing an airplane, I start with my flows, go through my GUMPS (Gas-Under carriage- mixture- props- seat belt) checks, then do the printed checklist, and finally when on short final I call out “short final, cleared to land, three green.” I’ve had several passengers tease me about doing the “three green” call out while I was flying aircraft that didn’t have retractable landing gear. But, I’d much rather be in the habit of checking every time regardless of what I’m flying than forgetting to check when it is necessary.
Use your available resources and develop healthy habits: If I have someone riding with me, I generally ask them to confirm that there are 3 green lights glowing on the instrument panel. Even if that person isn’t a pilot, they will probably enjoy the opportunity to be involved, and it’s a good way for me to stay in the habit of checking the gear lights to ensure that everything is properly down and locked. I’ve also found that intentionally leaving your hand on the gear lever until you have gear safe lights is a good idea. Forcing yourself to keep your hand on the handle until you have the all important lights obligates you to actually observe the indications instead of simply throwing the lever and moving onto something else. This way, if you only get an indication of 2 greens you’ll be aware of it right away and have more time to respond appropriately. It also helps you to learn the normal length of time it takes for the gear to extend or retract, which will be helpful to you to be aware of any abnormalities in the gear system.
Upgrade your aircraft’s gear-up warnings: There’s a variety of ways you can improve your aircraft’s ability to warn you of a potential gear-up landing. For student pilots or pilots new to complex aircraft, it could be something as simple as a red post-it note on the panel to remind you to verify the gear position prior to landing. Or, if you own an aircraft that doesn’t have an effective way to warn the pilot of a gear-up landing, consider investing in an aftermarket gear-up warning system – surely the extra price of such an upgrade is a small amount next to the cost of repairing the damage from a gear-up landing!
It can happen to anyone! The gear handle in this C-17 was in the “UP” position. (Photo Credit:https://theaviationist.com/2009/02/09/c-17-gear-up-landing-in-bagram-images/)
Always remember, regardless of experience, no pilot is immune to the possibility of a gear up landing. The best way to safeguard yourself is to discipline yourself in the use of flows, checklists, and call outs. Things like gear warning horns, visual reminders, and other systems are a useful back up, but they shouldn’t be relied upon to save your bacon if you don’t get the gear down at the proper time. Fortunately, in most gear up landings, the pilot and passengers are able to walk away uninjured – but that doesn’t lessen the embarrassment or financial burden of the event. So, keep your chin up, your gear down, and remember….THREE GREEN

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.

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.
Cirrus SR22 Equipped with Dual G500 TXi Screens and Dual Garmin GTN 650Xi GPS Units
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.

When it comes to turboprop engines, a hot start is a really bad thing. For you piston drivers out there thinking, “What’s the big deal, you are just starting a hot engine,” then here’s a little education for you.
In a PT6 turboprop engine, there is a very important temperature gauge that a pilot monitors very closely during each and every start. It is called the Inter-Turbine Temperature gauge, or ITT. This temperature is a measurement of the exhaust gases between the compressor turbine and the power turbine (s). In the picture below, the probe is located where the blue and red colors meet.
In a turboprop engine, specifically the Pratt & Whitney PT-6 in all it’s different sizes and variations, there will always be a specific temperature that the pilot will want to keep the ITT below. This article will deal specifically with a Piper Meridian.
A Piper Meridian starts hotter than almost any other PT6 engine because of the way it’s air intake is designed. Unlike other turboprops, the Meridian has a permanently open inertial separator. This means that not all the intake air makes it to the engine during start because some of it goes out the inertial separator opening. So, coming to a Meridian from operating other turboprop engines can lead to a little bit of a surprise on the ITT temperature being higher than what a pilot is used to when starting.
As a rule of thumb, when starting a Meridian, never let a start continue when the ITT hits 875 degrees. Based on the chart below, you are still in the safe zone at 875 and have about a 50 degree buffer before you have to start getting worried.
On cold starts with a good battery or a GPU, 875 is typically not an issue. Most starts when cold are going to be in the high 700s or low 800s. On a cold start, if you are seeing starts in the mid to upper 800s, try starting with a GPU and see if that lowers the start temperature. If it does, then that means your battery is weak and needs to be replaced. Another tell-tale sign of a weak batter is the Ng doesn’t spool up properly (meaning it settles around 12-13%) or takes a really long time to spool up. Also, never start on the battery with less than 24 volts.
When there are multiple flights in one day, the pilot has to take into consideration the warm engine prior to starting. If the ITT, prior to the start sequence, is above 150 degrees, it is time to do some motoring of the engine.
What is motoring? It is simply using the starter to turn the engine, which leads to air being sucked into the engine allowing the engine to cool off prior to start. The theory is, the cooler your engine prior to start, the cooler the ITT peaks at during start.
Here’s the steps on how to dry motor a Piper Meridian:
Battery on
Strobes on
Fuel Pumps and Ignition off
Throttle idle
Condition Lever feather/cutoff
Push the start button
Monitor the ITT temperature
Reaching 150 degrees, if less than 30 seconds have elapsed:
Fuel Pumps on
Ignition On
Condition Lever run
Reaching 150 degrees, if 30 seconds have elapsed:
Push Manual/Stop button to stop the start
Let starter rest for 30 seconds
The starter has a 30 second limit on the Meridian, followed by a 30 second rest period. You can do the sequence twice, then, after the 3rd start, there is a 30 minute rest period. Typically, if the ITT won’t cool down to 150 after the 3rd time, there is probably something wrong.
The most important thing a pilot can remember is never, ever push the condition lever forward if the ITT is above 150 degrees. You’ll be well on your way to avoiding hot starts that way.
