Sadly, Texas Top Aviation is having to cancel it’s 2020 Santa Fe Fly In due to COVID. New Mexico has continued to implement travel restrictions, making it difficult for Texas Top Aviation to complete the event.
Mark your calendars now, though, as Texas Top Aviation has scheduled is 2021 Fly In. We are returning to the Lajitas Golf Resort in the Big Bend area of Texas. The event will be March 24th-26th, 2021. Stay tuned for more information. We hope to see you there!
I began flying a Piper Malibu earlier this year. For those of you not familiar with the original PA-46, a Malibu has a Continental TSIO-320 engine, with 310 HP. It’s pressurized and cruises at about 185-200 KTAS.
A few things are introduced to the equation when pilots start flying higher, faster, and farther. When you start flying over longer distances, weather becomes more of an issue. On a quick hop from, say, Austin to Dallas, you can be pretty sure of what the weather will be since it’s a short trip. When you fly from Austin to LA, leave in the morning, land once along the way, and arrive in the afternoon after spending six and a half hours in the air, weather can change a lot in that amount of time.
A must for any pilot flying high and over long distances is some kind of Nexrad system, whether it be a Garmin 696, or it shows up on your GPS or MFD. Having this situation awareness is very helpful when planning ahead as to what to do about weather. A stormscope is also a handy tool, since you can see where the lightning is with it.
Cold fronts can be pretty nasty, depending on how strong and how fast they are moving. A strong, fast moving cold front usually has a lot of convective activity associated with it. The tricky thing with storms associated with fronts is that storms form in lines, most of the time. If you’re trying to cross a front in the morning, you can usually get high enough over the clouds with a pressurized airplane since the temperature is still relatively low to get clear of the cumulonimbus clouds. The cloud tops will only be around ten or twelve thousand feet.
Crossing fronts in the afternoon when daytime heating is pushing the tops of the CBs up to the 20-40 thousand foot range, it’s best to land, have a meal, stretch your legs, and wait till the sun starts to go down before pushing on. Do not, under any circumstances, try and go through the cumulonimbus clouds associated with a cold front in a small airplane. Not only is it uncomfortable (the turbulence bounces you around pretty good), but you’ll get ice, scare the passengers, and, if you’re in the heart of a storm, the plane could come apart.
When crossing mountains, the weather is always highly unpredictable. If it’s a clear day, no matter your altitude, you’ll probably pick up some turbulence from all the rising air off the peaks. If there is moisture in the air, there are going to be isolated to scattered thunderstorms in the summer time. The advantage of flying high when there are isolated or scattered storms is you can utilize the see and avoid method.
See and avoid is simple. When the storms aren’t embedded in other clouds, it’s actually rather easy to spot the big, rising clouds and go around them. The same concept holds true when avoiding those pesky pop up thunderstorms in humid areas like Houston and Florida.
One thing that I learned this summer was this. Sometimes, with an area of closely grouped storms, the cloud base is actually quite high (some storms I went underneath in New Mexico had cloud bases of 15,000 MSL). The thing to do here is just stay below the bases of the clouds and go around the areas of rain. These will be visible and you’ll be able to navigate around them. With bases even as low 9-10 thousand feet, it’s a much better idea to stay below the clouds, sacrifice some speed, and dodge the rain shafts.
The most important concept to take away is don’t fly into a thunderstorm. If there are a bunch of really high clouds in front of you and you don’t see a safe way around them, descend down and land, wait it out, and then continue on your way.

Diamond has joined the high performance single engine fray with the announcement of it’s new line of DA50 models. Cirrus currently has the cornered the market on easy flying, fixed gear, speedy HP single engine airplanes. But, (assuming that the Diamond DA50 gets certified in a timely manner and the appeal of the Jet A sipping SMA diesel engines appeals to a broad enough audience), Cirrus could have some competition soon.
The proposed Diamond DA50 will come in 3 different configurations, the IV, the V, and the VII. The IV and the V will each burn under 10 GPH of Jet A. The VII will burn about 14 GPH of Jet A, using the same amount of fuel as a normally aspirated SR22, but at cheaper Jet A prices (plus the discount of fuel companies like CAA or AEG Fuels).
According to AOPA, all 3 Diamond DA50 models will be equipped with the Garmin G1000 NXi panel and the GFC 700 Autopilot. The Diamond DA50 -V will be the first model expected out next year, with the IV to follow soon after. The wait for the VII will be a bit longer.
In testing, the Diamond DA50 -V showed true airspeeds of 173 knots with an expected range of almost 1100 miles. Gone is the bubble canopy that greatly increased the green house affect of the airplane. It’s replaced by two suicide doors, similar to what is on the Cessna TTx. The single back seat door on the pilot’s side remains.
Carrying capacity will be greater than the Cirrus as well. The Diamond DA50 -V will have a gross weight of around 4,000 pounds, giving it a useful load of 1,250 pounds, giving pilots a lot more flexibility in weight carrying. The Diamond DA50 exterior will be fully customizable as well as advances in carbon fiber paint and decals has come a long way since the early 2000s when white was the only option.
Here are some basic specs for each DA50 model:
Diamond DA50 -IV
Diamond DA50 -V
Diamond DA50 -VII
I am most excited to see the performance numbers on the VII model when it comes to market. With a 360 HP engine and retractable gear, it seems like it will be a screamer.
There are also rumors that Diamond is working on a rotorcraft, the Dart 280, but there isn’t a flying model at the moment.

Skyvector has changed it’s look. The aeronautical chart website is now offering flight plan filing capability. In order to gain the ability to file flight plans, the user has to form an account first.
Personally, I really liked how Skyvector had a simple interface before they changed. As an instructor, a lot of times, I go to multiple airports on one flight. It was really nice to just plug in airport IDs to check distances and heading information on Skyvector. The new format is a little clunky as the website has made it a little more difficult to do what it did best before.
Did the aviation community need another venue to file flight plans? Not with Foreflight, Garmin Pilot, and WingXPro leading the way in the app market. Skyvector was smart in not trying to develop another app to compete with the big boys.
Will the new Skyvector last? We’ll see. I’m hoping they’ll go back to the way they used to be, but we’ll see. I may use it enough to come around to liking it.

We’ve all heard it said…”reduce the throttle by no more than 1-inch every minutes to ensure you don’t shock-cool your engine”. Does this advice apply to a PA46 engine? Can a PA46 engine (Lycoming 540 or Continental 520/550) really be shock-cooled? How should the engine temperature be managed?
Metals expand and contract with temperature, and the various metals in an air-cooled aviation engine expand and contract at a different rates. Shock-cooling supposedly occurs when the engine changes temperature quickly and the different metals in the engine cool (and therefore change shape) at different rates. When the change occurs dramatically supposed scoring, rubbing, and marking of the metal can occur, which can cause catastrophic results.
So, let’s back to the original question…can a PA46 engine suffer shock-cooling and should a pilot operate the engine so as to avoid shock cooling? Simply put, I’ve never seen nor heard of any piston PA46 engine suffer shock-cooling. In 5000+ hours flying the piston PA46 and 16 years of flying/managing/training in the Malibu/Mirage/Matrix, it simply has not happened to me nor anyone I know. Does it mean that it cannot happen or has never happened? No. But, it is certainly not a prolific threat to our fleet.
Should the owner/pilot operate the engine with a cautious eye cast toward the potential of shock cooling? Well, sort of…but, let’s flesh this out. My suggestion is that a pilot should operate the engine with conservatism in movement of temperature, but only because this is a good operating practice with any machine, and any flying machine is (by definition) not “overbuilt”. And, there are many ways to change the temperature of the engine…not just by reducing power. Here’s a partial list of ways to cool your PA46 engine:
My suggestion is that a pilot only perform ONE of these actions at a time when beginning a descent. This suggestion was presented to me by Chad Menne (Owner, Malibu Aerospace) some time ago and I’ve operated engines this way ever since. If you are at a higher altitude and simultaneously reduced the power, lowered the landing gear, started a big descent, and enrichened the mixture in one flail swoop, I think there’s a chance that your engine would suffer some negative effects that could be called “shock cooling”. So, when you do start a descent, pick one “cooling action” to accomplish at a time. I’m sure you’ll not hurt your engine.
Simply put, shock cooling is not a huge factor in the PA46 community, and a PA46 pilot does not need to be overly cautious. The “one inch per minute” rule may apply in some other airframes, but in the PA46 world it is not applicable.
Joe Casey’s aviation story began in 1990 with his first flight near Nacogdoches, TX in a Cessna 172. From lift-off, Joe knew he would have a lifetime passion flying just about anything that will leave the ground…He was completely hooked.
Along with being an FAA Designated Pilot Examiner (DPE), Joe is an ATP/CFI-AHMG and Commercial Rotorcraft/Glider Pilot in the civilian world and also a UH-60/AH-64 Pilot-in-Command/Instructor/Examiner Pilot in the US Army Reserves. His passion for the last 19 years, however, has been the PA-46 Malibu/Mirage/Matrix/Jetprop/Meridian. Has has amassed over 6,500 hours in various PA-46 airframes and believe it to be one of the finest flying machines available for the serious cross-country pilot with an eye for efficiency.
Now, Joe has flown more than 12,200 hours in just about every imaginable environment. Whether providing initial/recurrent training in the PA-46’s, TBM’s, instructing in NVG’s in a UH-60 Blackhawk, flying the King Air series of airplanes, giving tailwheel endorsements, or taking kids flying for the first time, he simply loves flying machines and the people who fly them.

It’s winter time, which means it’s time to use those Piper PA46 de-ice boots a little more often. Most of us know the winter flying rules, don’t stay in ice, get rid of frost, etc. However, most of us aren’t as familiar with how to maintain those Piper PA46 de-ice boots. The do need some TLC every couple of months to keep them in tip top shape.
Below is the recommendation from Goodrich (the maker of the boots) on what to use to clean and polish the boots and how often to do it.
Steps 1-3 below are your twice a year items to make your Piper PA46 de-ice boots last through the lifetime of the aircraft.
ShineMaster Prep strips all the dirt, grime, grease, oil, silicone products and old ShineMaster on the Piper PA46 de-ice boots to prep them for Step 2.
ShineMaster Prep can be found on Goodrich’s website.
AgeMaster is your second step the in the Piper PA46 de-ice boot preservation and protectant process. AgeMaster is a rubber preservative that protects against weathering, ozone, and ultraviolet rays.
Make the first application when your de-ice boots are 6 months old, then re-apply every 150 hours (or twice a year) after that.
AgeMaster #1 can be purchased on Goodrich’s website.
Step 3 in the Piper PA46 de-ice boot care is ShineMaster. As the name implies, ShineMaster shine’s the boots up after getting rid of all the old gunk & grime with ShineMaster Prep and after AgeMaster is applied. 2-3 coats should be sufficient.
ShineMaster can be purchased on Goodrich’s website.
During icing season, Goodrich recommends ICEX II. ICEX II is an ice inhibitor that should be applied every 50 hours during ice season. This will help prevent ice from sticking to the Piper PA46 de-ice boots. ICEX II can be found here.
Finally, for general cleaning of the boots after each flight, utilize Goodrich Aerospace Cleaner to debug, then follow up with Goodrich Aerospace Protectant. Goodrich claims their Protectant will resist dust, soiling, and staining. There may be less bugs to clean each time!
With just a few hours a couple times a year spent working on the Piper PA46 de-ice boots, owners will never have to worry about the hefty price tag of boot replacement!

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.
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.
