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.

Bonanza Cover — 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.

Selecting the Proper Altitude
ByHank Gibson August 28, 2015September 6, 2015

One of the first questions a student pilot asks me when starting the cross country portion of his or her training is, how do I know what altitude is best for my flight? This is a good question, because without taking certain aspects of the flight into account, it’s really just a crap shoot when selecting an altitude. Craps and flying don’t mix, so let’s take a look at a few considerations when selecting an altitude.

Sky Coverage

Sky coverage has several subcategories when it comes to selecting an altitude. First is how high are the bases? Is it IFR (VFR pilots would be grounded), marginal VFR (1,000 AGL to 3,000 AGL ceiling), or good VFR (above 3,000 AGL ceiling)? If the cloud deck is only 2,500 feet off the ground, then VFR pilots are limited to either 1,000 AGL to 2,000 AGL. This is an excellent segue into why VFR pilots shouldn’t scud run!

Second, what kind of cloud deck is it? Is it an actual ceiling (broken or overcast), or is it a scattered layer? Few or scattered layers usually allow VFR pilots to find a hole to get higher to some smoother air, making the flight more pleasant. VFR pilots, always make sure to check the destination weather as it could be scattered where you are departing from, but it might be broken or overcast where you are arriving.

Last, how high are the tops of the clouds? Pilots can only get this information in the planning stage from the area forecast or from pilot reports, so most of the time, it’s not very precise information. If the tops are at 10,000 feet and the pilot is flying a 172 on a 30 mile trip, it doesn’t make much sense to get on top of the clouds.

Terrain and Obstacles

Terrain goes hand in hand with sky coverage. If there are low clouds and high terrain, that doesn’t bode well for trying to stay VFR and not hitting anything. Obstacles need to be taken into account too, as there are some pretty tall radio towers that can stretch up into a 1,500-2,000 AGL deck of clouds.

Winds Aloft

Once the sky coverage and terrain have been considered, it’s time to look at the winds aloft. Tailwinds are preferred, but, sometimes, a headwind is the only option. After taking the clouds and terrain into account, this narrows down your altitude to a handful of options. The winds aloft will further narrow it down.

Aircraft Performance

Once you have two or three altitudes in mind, taking a look at the performance charts for your airplane will help nail down that final altitude. Pull out the POH, compare fuel burn and cruise speed, and you’ll have your altitude selected.
Cessna TTx Production Ceases
ByHank Gibson March 21, 2018May 1, 2018

Sadly, in January, a pretty great airplane was put out to pasture. Textron (the conglomerate that now owns Cessna, Beechcraft, Hawker, and Lycoming) announced it was ceasing production of the Cessna TTx. With the end of the Cessna TTx production, an airplane that was the main “competitor” to Cirrus (if you can call it competition; Cirrus consistently outsold the Cessna TTx by a wide margin each year), it leaves the SR series to stand alone atop the High Performance piston single market.

I got to go through Cessna’s FITS Accepted Instructor (CFAI) course back in 2012 and have flown in the Cessna 350 and 400 (which is what they were known as at the time; the Cessna TTx name came around in 2011) for about 120 hours. I really like the airplanes. I’m partial to the Cirrus, but the Cessna 350 & 400 are fast airplanes and great for 1-2 people. I flew a 350 (the non-turbo charged version) from New York to San Antonio last fall and routinely saw 170 knots at 12 GPH.

Columbia started out making the 350 & 400 (the turbo-charged version) in the early 2000s, but went bankrupt in 2007. Lancair started Columbia to make a certified version of their popular kit planes. If you see a Lancair ES floating around, you would swear it’s a Columbia with only 1 door. Cessna bought the design from Columbia in 2007 to begin manufacturing the airplanes themselves.

Cessna then made a huge mistake as they moved the production facility from Bend, Oregon to Mexico. Production completely halted in 2009 as the planes coming out of Mexico were found to have defective composite work. The sales never really recovered, even though Cessna put the Garmin G2000 panel in the Cessna TTx, complete with a touchscreen key pad. A FIKI system was added as an option in 2012.

A prospective buyer can still get a great value on a used 350, 400, or TTx, as they are valued a little lower than a Cirrus. The 350, 400 or TTx all make excellent single pilot or two person speedsters with very comfortable amenities.

What’s Going On With the Airplane Market?
ByHank Gibson June 22, 2026June 30, 2026

An Airplane Market Update, Q2 2026

I get asked some version of the same question almost every day right now: “Hank, what’s going on with the airplane market?” Owners are nervous. The market has definitely slowed down, and the second quarter has been especially quiet. So let me give you a straight read on what’s actually happening, why, and what it means for your airplane.

Here’s the short version: don’t panic. A slow market is not a market crash. It’s a market that rewards sellers who price realistically and buyers who are ready to pull the trigger. Patience is the name of the game right now.

Where values have actually been heading

Used airplane values shot up through the COVID years, peaked somewhere around 2022, and have been softening ever since — really since about 2023. That’s carried into 2026. But in most piston airplanes, it looks a whole lot more like a slow, steady give-back than a crash.

Now, here’s where I’d rather look than at asking prices. An asking price is just what a seller is hoping — or dreaming — to get; it isn’t what the airplane is worth. What an airplane is actually worth is what VREF tracks. And when I pull the VREF values on the single-engine pistons I’ve been appraising lately, a clear pattern shows up:
- Older and less expensive airplanes are holding up the best. A clean normally-aspirated G1, G2, or G3 Cirrus SR20 or SR22 is down about 3% over the last twelve months. Older, more classic airplanes — Bonanzas, a Cherokee Six, a clean P210 — are flat to down just a few points. One outlier is the Cessna/Columbia 400 market — those are down about 13%.
- The newer and more expensive, cabin-class singles have dropped more. A pressurized Malibu Mirage is down around 12% on VREF value, with other PA-46 pistons and turbines valued a little better, but still down between 8–12% over the last year.
Call it roughly 5% on average across the segment. That’s more than the under-1% you’d guess from asking prices alone — but it’s still less than 15% down over the last year, not a crash. The rule of thumb: the older and less expensive the aircraft, the better the values are holding; the newer and more expensive the aircraft, the more the value has dropped over the last year.

What a Crash Actually Looks Like

Worth being precise about what I mean. A real crash — like 2008–09 — is sudden and disorderly: values plunge almost overnight, financing dries up, buyers walk away from their deposits, and airplanes sit because there’s no one to buy them at any price. New business-jet deliveries fell nearly 34% in a single year, and it took years to climb back. What we have now is the opposite on every count — value drops of 15% or less, financing that’s tighter but still available, and airplanes that are still changing hands. That’s a soft, orderly market, not a crash.

Why Q2 got so quiet

A handful of things piled up at the same time. None of them is a disaster on its own, but together they explain why the phone has been ringing less.

Rates didn’t come down the way everybody expected. Oil shot past $110 a barrel after the conflict with Iran, inflation came roaring back, and the Fed stopped dropping rates — so financing an airplane still costs more, and that takes the urgency out of buyers. Financing also got tighter; the days of 100% loans with no money down are basically over, and lenders want bigger down payments.

The tax rush already happened, too: when the One Big Beautiful Bill brought back 100% bonus depreciation, it set off a mad dash to close before year-end, and a lot of the folks who’d have been shopping this spring already bought last winter. Plus, there are simply more airplanes to choose from now, which hands buyers options and pulls pricing power away from sellers.

So what should you do?

It depends on which side of the deal you’re on.

If you’re selling, price to today’s market — not the 2022 peak, and, unfortunately, not what you paid for the airplane. Realistically priced airplanes are still selling; the ones that sit are the ones chasing a number the market left behind. Keep your logs complete, stay current on inspections (don’t forget those 24-month IFR inspections!) and ADs, and present the airplane well. Have a thorough annual done before putting it on the market. Keep it clean and do whatever cosmetic or avionics fixes or upgrades you’ve been neglecting — you want it to show as well as possible, because there’s a lot of competition out there.

Re-dyeing the leather seats is a cost-effective way to spruce up the interior without replacing the seats. A good wash will certainly help the exterior. Glass in the panel always shows better than steam gauges, so even something simple like an Aspen upgrade, two Garmin GI 275s or G5s, or a 7-inch Garmin G3X will bring value to your airplane and make it show better — any of those are less than $10,000. If you do still have a Garmin 530W or 430W, consider changing them out for a newer Garmin or Avidyne IFD unit; Garmin won’t support the 530W/430W anymore. And Avidyne is quietly ending support for the Entegra system this fall — but the good news is the Avidyne Vantage panels are finally certified.

And if you can wait, give it some thought — the back half of the year is shaping up stronger. The fourth quarter is traditionally the best stretch for used sales, and now that bonus depreciation is permanent, that year-end push resets every fall.

If you’re buying, this is your window. Higher rates have thinned out the competition, there are more airplanes to pick from than there have been in years, and sellers are more willing to deal. If you’ve got cash ready or financing lined up, you’ve got leverage you didn’t have eighteen months ago. Be picky — buy the clean one with good records.

If you’re just holding, relax. There’s no reason to panic-sell. Most piston values are easing off slowly, not collapsing. Patience wins here.

The right move always comes down to your specific airplane, your timeline, and what you’re trying to accomplish. If you’d like a current valuation — or just an honest read on where your airplane sits in today’s market — give me a call. That’s what we’re here for.
Breathing…It’s The Difference in Engine Performance
ByJoe Casey November 27, 2018November 27, 2018

The PT6 engine that’s found on the Jetprop and Meridian is designated a -21, -34,-35, or a -42A. The Continental engine on a Malibu is either a TSIO 520 or a 550. What’s the difference? Why should I care? Most pilots don’t understand the difference, but it’s pretty easy to understand…and it’s all about breathing.

Whether a piston or a turbine, the engine has a ratio of fuel/air that works best. For a piston model, we can make adjustments to this ratio by adjusting the mixture. In climb we use a richer ratio to help cool the engine, and in cruise we lean the mixture to save fuel since we don’t need the extra fuel for cooling (due to higher speeds which cools the engine). In the turbine, the ratio is set and there’s nothing that can be done about it…except climb to a higher altitude. But, more about that in a second..let’s go back to the piston discussion…

Piston: A Continental 520 engine and the 550 engine are flown exactly the same. On takeoff, both will develop 310HP (38″MP with the 520, 35.5″MP with the 550). So, why would a pilot want a 550 in his airplane as opposed to a 520? The answer is breathing.

A 520 is named appropriately because the engine displaces 520 cubic inches of air with each complete cycle of all 6 cylinders. To determine the displacement, just figure the bore (diameter of the cylinder) and the Stroke (how far the piston travels in the cylinder) and plug the numbers into this formula:

CID = Bore X Bore X 0.8754 X Stroke X # of Cyl.

Here’s the bore and stroke of the Continental 520 and 550 engine:

TSIO 520: Bore = 5.25″ and Stroke = 4″
TSIO 550: Bore = 5.25″ and Stroke = 4.25″

So, you can see the two engines are exactly the same except the 550 has a little longer stroke, and therefore displaces a little more air. Said another way…it the sucks the air into the engine a little better.

So, with this knowledge, the ability for the engine to breathe becomes a little more clear. Both a 520 and a 550 will perform exactly the same until the point that a 520 simply cannot suck enough air and begins to develop less MP as a result. For most 520 engines, this will happen somewhere around 18,000 ft. But, it is dependent upon a myriad of factors including: health of the engine, altitude, temperature, and atmospheric pressure. When the 520 hits this point, the throttle can be full-forward, but the engine will not develop full MP, but some number that is less. I’ve seen a max MP at FL250 in a 520 Malibu to be about 31″MP. So, you can probably guess that the rate of climb will correspondingly suffer as the engine develops less MP. How do we fix this problem? Enter the 550…

Since the 550 displaces more air, the engine will maintain max MP to a higher altitude. When the 520 begins to develop less power at about FL180, the 550 engine will be able to continue to maintain 35″ at a higher altitude. Make no mistake…the 550 will also hit an altitude where is cannot develop 35″MP, but this altitude will probably be nearly FL220. So, the 550-powered Malibu will reach cruising altitude faster than the 520.

But, at cruise both engines are pulled back to 30″MP. So, either engine will deliver the same cruise speed because they are both able to develop 30″MP at any altitude. Does it really matter if you’ve got a 520 or a 550 engine? Answer: not much. Both are excellent engines and both will deliver the airplane to the destination, but if the chosen altitude is above FL180, the 550-powered airframe will probably arrive a few minutes earlier. Which would I want if I were purchasing an airplane? It’s not a big enough deal, IMHO. I’d select the best airframe/engine/prop combination and not put much weight into the 520 vs. the 550.

Turbine world: So, how about the -21, -34/35, and -42A compare? Here, there’s big difference, but it’s still all about the breathing. A -21, -34/35, and -42A are all derivatives of the famous PT6 family of engines, and all are designed to be 1000+SHP engines de-rated to fit the airframe. For instance, the -42A engine is 750SHP when mounted on a King Air 200, but the same engine is derated to 500SHP when mounted on the Meridian. Ditto with the -21 and -34/35 engines…all are de-rated. So what’s the difference? Breathing…

At the lower altitudes all will develop their maximum rated SHP, meaning they will all develop maximum torque. And, down low there’s plenty of air to breathe so the engine has no problem developing that torque at a low ITT. But, as altitude is gained, the engine must suck more air to develop the same torque, and the ITT goes up. At some point in the climb (depending upon altitude, temperature, pressure, and IAS) the engine will not be able to produce max torque without exceeding Max ITT. At this point, the engine cannot breathe any more (suck in anymore air), and the power (torque) developed falls off. With the -21 engine, the power falls off quite dramatically because the engine simply cannot breathe well. It is a smaller engine and more air cannot be forced into the compressor section. For the rest of the climb the engine is “ITT limited” and the performance will suffer.

The -34/35 engine is a little bigger and will develop maximum power (torque) to a higher altitude. And, when the torque does drop off (as altitude is increased), the rate of decrease is less because it can breathe easier due to it’s larger size. Guess what? The -42A will beat out the others and develop max torque to an even higher altitude. With this decrease in torque available also comes a welcome friend…less fuel burn. Altitude is the friend of any turbine pilot, and he/she will climb to the highest altitude possible to save on fuel.

The end result is the -21 powered Jetprop will cruise at 238 KTAS (in the summer) with a fuel burn of only 28gph. The -34 will have higher torque than the -21 and will develop more SHP and will have a higher cruise (260 KTAS in the summer) with a correspondingly higher fuel burn (32gph). The -42A will be breathing easily at higher altitudes, and will develop the most torque, but with a fuel flow of 39gph. The Meridian (with the -42A) will not out-perform the -34/35 Jetprop in cruise purely because the Meridian is much heavier.

Just remember…fuel flow in a turbine is always commensurate with its ability to breathe and a turbine’s ability to breathe is a function of the engine’s ability to breathe.

With this knowledge…let’s check your understanding. Answer this question: Will a Jetprop cruise faster in the summer or winter? Remember, cold air is more dense than warm air, and an engine will develop power according to it’s ability to suck in air. More air available, more power available. Answer: Winter.

A good analogy: I’m a Cross-fitter (meaning I do crossfit workouts a lot). In the gym we have various workouts that test a person’s ability to perform. Guess who usually does the best? Right…the guy who can breathe the best. A person is nothing more than an engine…we intake air and combine it fuel and burn it to develop energy. In Crossfit, the person with the biggest engine (muscles that can develop power) that can sustain power (good aerobic capability) will win almost every time. The only variables then are genetics (how well-made is the engine), flexibility (you’ve got to be able to get into the position), and skills (there are more efficient movements). A good Crossfitter will work hard on mobility, skill, and try to increase the bodies ability to increase capacity through a tough workout.

To get maximum performance, the pilot cannot change the engines skill or mobility (at least not without an engine change!), but a thorough understanding of the how the engine breathes will help him/her use the power that is available to the fullest.

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.
2022 Texas Top Aviation Fly In is in the Books!
ByHank Gibson June 20, 2022June 20, 2022

Thank you to everyone who made the 2022 Texas Top Aviation Fly In at the Hilton Santa Fe Buffalo Thunder Resort a success!

We had 22 attendees and 12 airplanes make it out to beautiful Santa Fe, New Mexico for the week.

After 2 days of very competitive golf, Chris Travland was our 2022 Texas Top Aviation Fly In Golf Tournament Champion.

While you are out in Santa Fe on your next trip, go check out the Rancho de Chimaya restaurant. It was excellent and a true New Mexican experience.

Mark your calendars for the 2023 Texas Top Aviation Dallas Fly In at the Westin Stonebriar Resort in Frisco, TX. McKinney National Airport (KTKI) will be our host airport. The event will be April 12th-April 14th, 2023. Hope to see you all there!
Conroe, TX CPPP
ByHank Gibson August 31, 2016September 15, 2016

The Cirrus Pilot Proficiency Program (CPPP) will be coming to the Galaxy FBO at the Lone Star Executive Airport in Conroe, TX again this year. The dates of the event will be October 14th-16th.

Wondering what the CPPP program is?

“CPPP offers a weekend event for Cirrus owners and their partners that focuses on Cirrus-specific knowledge and flying proficiency. We bring some of the most experienced flight instructors who regularly teach in all kinds of Cirrus airplanes flown for all kinds of missions. We have prepared an extensive syllabus of ground courses that complement the transition training and delve into areas of greatest need for Cirrus pilots.” (from CirrusPilots.org)

The weekend starts off with a group dinner on Friday night. The Saturday morning ground session focuses on General Aviation Safety with special focus on the Cirrus accident statistics. Normal and emergency procedures are also reviewed.

In the afternoon on Saturday, the attendees are split into two groups. The first group has a myriad of options for ground sessions covering all topics related to Cirrus aircraft and operations. The second group flies, then they switch for the second 3 hour session. Sunday brings the same split, with more courses offered and more flying.

While the Cirrus pilots are flying and learning more about their airplanes, CPPP offers a Partner in Command course for flying partners on Saturday. This allows flying partners to be more comfortable in the airplane and teaches them what to do if something were to happen to the pilot.

All in all, attending a CPPP will improve both Cirrus knowledge and Cirrus flying skills. It’s highly recommended for all Cirrus pilots.

To register for the CPPP event in Conroe, check out the CPPP website.
