An Educational Runup

ByHank Gibson July 23, 2020July 17, 2020

When a pilot thinks of an engine runup in a single engine piston airplane, typically it is let’s find out if the engine is running rough or not, meaning a spark plug is fouled. Believe it or not, there is a little more to learn from a runup than just checking the spark plugs.

A distinct advantage to having an engine monitor that monitors all EGTs and CHTs is you get a better idea of engine health. When switching to one magneto or the other during the runup, all the EGTs should rise, showing that the temperature of the exhaust gas is going up from each cylinder. This occurs because when running on only one magneto and one set of spark plugs in each cylinder, the mixture takes longer to burn, so, when the exhaust valve in the cylinder opens, the burn is still on going and this hits the EGT probe, causing a temperature rise. An indication of a magneto failure in flight would be a rise in all the cylinders EGT without a change in mixture setting.

Now that we know what to look for when checking each magneto, what would one look for to show that there is a problem? The basic that each student pilot is taught still applies. The engine manufacturer puts a limit on RPM drop during the runup. When checking one magneto or the other, watch for an excessive RPM drop. If the RPM drops past the limit, this usually will be accompanied by engine roughness.

Why is that? Let’s look at the cause for the excessive RPM drop. For this, we need to go back to our EGT indicators. Let’s say we have a 6 cylinder engine. When the key is turned to the right magneto, the RPM drops 250 RPM and the engine gets very rough. Look at the EGT gauge. The cylinders where the spark plugs are firing normally will all show a temperature. The cylinder (or cylinders) where there is no combustion, meaning a bad plug, will show no temperature. This is because the mixture is just sitting in the cylinder and not igniting, therefore, no exhaust gases will be pushed out so there will be no EGT indication for that cylinder. This is also how you tell a mechanic which cylinder to check for the bad plug.

It could also be a bad magneto. If multiple cylinders EGT all drop, or the engine wants to quit entirely, you have a bad magneto or bad ignition harness.

What else can you learn during the runup? Electrical system health is key, especially in all electric airplanes (meaning no vacuum system). It’s a very good idea to turn on all the lights and pitot heat to ensure that a rise is indicated on the ammeter. This means the alternator is carrying the load and working properly.

The next time you do your runup, keep an eye on your EGT to see the rise during a magneto check.

Hank Gibson Featured on Joe Casey’s The Malibu Guru Podcast
ByHank Gibson May 19, 2022May 26, 2022

Recently, I did my TBM and Meridian recurrent training with Joe Casey of Casey Aviation. I always like being challenged my more seasoned instructors than me because I always get to learn something. When I learn something, it makes me a better instructor and allows me to give better instruction to my customers. Plus, there is still a bunch that I don’t know!

Joe has a podcast titled The Malibu Guru (because he really is the Malibu guru!). During our training, we did a podcast together and he interviewed me. I get to tell about Texas Top Aviation and some exciting things coming up this summer (hint: the biggest exciting thing is called The Aviator’s Academy). Before I give too much away, take a listen to the podcast.

The Malibu Guru Podcast: Interview with Hank Gibson
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.
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.

Synthetic Vision Technology
ByHank Gibson December 5, 2014December 5, 2014

Let’s say you’re flying in the mountains of Colorado on a cloudy day. There’s a solid layer from the surface all the way up to 14,000 feet. You’re inbound to Eagle (KEGE) on the RNAV (GPS) D approach. There are mountains next to you and below you, but you aren’t concerned since you can see them all. The base of the last reported overcast layer was 3,000 feet, so you know you’ll break out before the MDA and land no problem.

At 11,100 over AWACC, you clearly see the top of the mountain below you. You are comfortably above it. You already have the runway in sight as well. You pop out of the clouds on the approach at 9,700 feet, spot the airport and follow the tower’s instructions to circle north of the runway for a left base for runway 7.

How could you see the mountains inside the clouds? You have Synthetic Vision installed on your glass panel, that’s how.

Aspen Synthetic Vision

Synthetic Vision, which has actually been around since the ’70s when NASA and the US Military first developed it, was first FAA certified for the Gulfstream PlaneView flight deck in 2009. Garmin, Avidyne, and Aspen are the main general aviation manufacturers of synthetic vision these days. All Garmin PFDs are now equipped with Synthetic Vision while Aspen gives you the option to upgrade to Synthetic Vision when you get one of their PFDs installed. Avidyne gives you Synthetic Vision in their R9 upgrade for the Cirrus.

What is Synthetic Vision? Basically, it’s a 3-D picture on the primary flight display showing terrain, obstacles, traffic, and runways. It greatly enhances situation awareness in areas of terrain or high obstacles during IFR conditions or at night.

The goal behind the development of Synthetic Vision was to decrease the amount of controlled flight into terrain (CFIT) accidents. A CFIT accident consists of a perfectly airworthy airplane flown by a pilot (or autopilot) unintentionally into terrain. These accidents can happen in low visibility conditions or at night, but the reason is mainly due to the pilot losing track of his position in relation to obstacles or terrain (or water as was the case with JFK Jr.).

With Synthetic Vision, the goal is to enhance pilot knowledge of what is around the airplane at all times. When you’re at altitude, the terrain below you looks flat. When you start descending down amongst the rocks, the hills or mountains start to rise up on your screen. For those used to the coloration with the 2-D terrain feature on a GPS unit, it translates very easily to the terrain coloration on a Synthetic Vision equipped PFD. Terrain that is between 100 and 500 feet below the aircraft is shown as yellow, while terrain closer than 100 feet is depicted as red.

Garmin Synthetic Vision

One neat feature on Garmin units is the Highway in the Sky. When a pilot puts a course or a flight plan in the GPS, the PFD displays magenta boxes at the altitude selected displaying the route. It’s handy when hand flying to just “fly through the boxes.” They also display descent angles on approaches.

Synthetic Vision is still optional on Garmin and Aspen units, but I highly recommend springing for it. It will give you a higher level of safety and keep you out of the rocks.
Scud Running
ByHank Gibson June 2, 2015

I was speaking with a pilot a few months back who was not instrument rated. He was telling me of his flying experience while continually speaking fondly of scud running. He told me several stories, most of the time with a smile on his face, about scud running to his destination while staying clear of clouds. While he was talking, my mind was cycling through the numerous accident reports I’ve seen where a scud running VFR pilot has crashed into terrain or an obstacle. Needless to say, scud running is not a very good idea.

This pilot’s stories got me to thinking, how common is the practice of scud running amongst VFR only pilots? As an instructor, I always teach my private students about personal minimums and making that no-go decision when clouds are below those personal minimums. The act of scud running falls under several of those dangerous pilot mindsets, get-there-itis, invincibility, and macho-ism, to name a few.

To bring everyone on the same page, let’s define scud running. Wikipedia has a very good definition:

Scud running is a practice in which pilots lower their altitude to avoid clouds or instrument meteorological conditions (IMC). The goal of scud running is to stay clear of weather to continue flying with visual, rather than instrument, references. This practice is widely accepted to be dangerous, and has led to death in many cases from pilots flying into radio towers and high tension wires; however, even instrument-rated pilots sometimes elect to take the risk to avoid icing or embedded thunderstorms in cloud, or in situations where the minimum instrument altitudes are too high for their aircraft.

To put some numbers with that definition, a scud running VFR pilot would takeoff with a 1200-1500 foot ceiling and stay 700-1000 feet above the ground, right in the area where towers, hills, and rapidly rising terrain reside.

How do we change this mindset? Well, if someone has been scud running for years without incident, the practice becomes normal, like the pilot I mentioned above. The mindset of invincibility sets in and the practice continues. This particular pilot can also lead other pilots to adopt the same practice, encouraging them that nothing will happen to them, since we all know that our pilot peers know better than our flight instructors (insert heavy sarcasm here).

In order to change this mindset, instructors need to emphasize personal minimums from day one. This includes ceilings, visibility, and winds. For a seasoned pilot, a review of accident statistics might help the process.

Scud running is not a safe practice. If you’re a scud runner, you need to rethink your attitude. Is getting there really worth it?

Still not convinced? Read this pilot’s experience from AOPA.
The Avidyne Equipped Cirrus Upgrade
ByHank Gibson October 27, 2020October 27, 2020

A History Lesson

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.
