Satellite communications company Iridium now has a really nifty little product called the Iridium Zoleo Satellite Communicator. Most pilots who fly newer Cirrus Aircraft will be familiar with the company name Iridium. Iridium manufactures the built in satellite phone that is an option in all Cirrus after 2012. The Iridium Zoleo brings messaging capability to any airplane in a cost effective and simple manner.
The Iridium Zoleo is a device roughly the size of a walkie-talkie. It links up with the Iridium satellite network to send and receive messages and emails anywhere in the world (or air!). To make things easier, the Iridium Zoleo links with a phone via Bluetooth to a free app that allows the user to write a message directly from the phone and send through the device.
The Iridium Zoleo is affordable at only $200. A plan has to be purchased in order to send messages, with 3 different levels of subscription offered: 25 messages a month for $20, 250 messages a month for $35, or unlimited messages per month for $50. Each plan offers a $6 upgrade to allow unlimited worldwide breadcrumbs and tracking.
The Iridium Zoleo has a 200 hour battery life and is designed to be shock, dust, and water resistant. Plus, the device has a built in SOS that can be used anywhere in the world. So, you can take it rafting down the Grand Canyon, hiking in the Andes, flying over the Atlantic, or SOS if you are stranded in the middle of the Indian Ocean.
Your about to make your dream aircraft purchase. The plane has low time on the engine, is reasonably priced, and, according to the seller, has no damage history. You are overjoyed! Your dream of making an aircraft purchase is finally coming true. You prepare your offer for the seller, set up the escrow account, and start all the paperwork.
Two weeks later, the airplane is yours! You start flying it, though, and the engine starts to have some strange vibrations. After several flights, it starts to get worse. You take it to your mechanic to get it looked at and you find out the airplane needs three new cylinders along with some other engine work that is going to total a lot of money. Plus, your airplane is now going to be in the shop for several weeks.
All that excitement you just had? It just went out the window.
Could this have been prevented? Probably so, with a logbook inspection and a pre-purchase inspection.
Aircraft Purchase: Logbook Inspection
Inspecting a logbook can be very daunting when making an aircraft purchase, especially for older airplanes. This is, however, one of the most vital steps in making a new aircraft purchase. You can find out many things from looking at the maintenance logs of an airplane. First, you can check the compression levels of the engine. Typically, you want compression levels in the 70’s, with it still being okay in the high 60’s. Anything below 65 and there could be potential problems.
Second, you can find out if there has been any odd maintenance done pointing to possible unreported damage history. This is rare, as most aircraft owners are honest and up front when talking about damage history. But, if there is an entry detailing a prop overhaul after only 50 hours on that prop, you may start to ask some questions.
Third, you can find out how well the airplane has been maintained. If a lot of maintenance was completed at each annual, even if it was a lot of small things, then the airplane has been maintained by a good mechanic who is very thorough. This also involves a check of the ADs, Mandatory SBs, SBs, and SLs that have been issued for the airplane. If all that has been kept up with, it’s a well maintained airplane.
Finally, it gives you a good idea of how much the airplane has been flown. Sure, the ad online will have the total time and time since overhaul, but you can look at the year by year breakdown of how much the airplane has been flown. It may have been flown a lot earlier in it’s life, but not quite as much recently. That’s not necessarily a bad thing, but airplanes like to be flown.
Aircraft Purchase: Pre-Purchase Inspection
Before making an aircraft purchase, it is extremely vital that whenever you are buying an airplane that you get a pre-purchase inspection done on the airplane. Even better is getting one done by a mechanic who specializes in that type of airplane (eg. Piper Service Center for Pipers, Cirrus Service Centers for Cirrus, Kevin Mead for PA-46s). A pre-purchase inspection can save you a lot of money in the end.
There is always going to be some kind of maintenance issue with an airplane being purchased, whether it is big or small. Once a pre-purchase inspection is completed, you can take the findings to the seller and negotiate for a lower price based on those findings, or just have the seller fix the items before the sale is completed.
I would recommend having the seller fix the problems before the sale is completed. Even though it may take a little longer for the sale to be completed this way, you’ll get to enjoy your airplane right away instead of it being in the shop the next several weeks after you complete the purchase.
There is the circumstance where the pre-purchase inspection reveals some serious airworthiness issues which would cause the deal to be voided. Always put this clause in a purchase agreement, giving you, the buyer, an out if there are serious airworthiness issues.
When it comes to making an aircraft purchase, it is not a process to be rushed. Slow and steady usually gets the best airplane for the money, giving you years of enjoyment in the future.

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.

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.
For years, there has been clamoring for airplanes to get rid of lead in piston engine Avgas. In the early 2000s, Thielert created a Jet A burning piston engine for Diamond Aircraft that gained some traction, but Thielert had internal issues and ended up declaring bankruptcy. Several other Jet A piston engines have come down the line since then to some success (Diamond is currently using 2 Austro manufactured Jet A piston engines on it’s DA62 and a Continental manufactured Jet piston on the new DA50).
The problem with a Jet A burning piston engine, though, is that those engines would be very expensive to put on existing airplanes, not to mention the cost of the STC alone.
Insert GAMI (General Aviation Modifications, Inc.), the famed Ada, Oklahoma company that championed turbo normalization, balanced injectors, and lean of peak operations. For those that have been to GAMI’s engine class, you know that these guys are at the very top of their game in engine knowledge.
In 2010, GAMI started the process of creating an Unleaded form of Avgas, terming it G100UL (the irony of traditional Avgas, 100LL, is the LL starts for low lead, but the lead levels in 100LL are actually quite high. UL stands for UnLeaded). Just before Osh Kosh in 2021, GAMI revealed that it’s work has come to fruition, gaining an STC for G100UL for Lycoming powered Cessna 172s.
The amazing thing about GAMI’s product is that it is able to mix with 100LL and not cause any issues. This means fuel trucks, fuel lines, fuel pumps, and aircraft fuel tanks don’t have to have any modifications to them to use G100UL. Plus, pilots will see longer engine life using G100UL because of the simple elimination of the lead. In tests, combustion chambers in cylinders burned cleaner, so theoretically, cylinders and engines will last a lot longer.
According to the company, GAMI has a few more tests to run and, assuming those go well, G100UL will be available for a whole lot more airplanes. An STC will still be required for the use of G100UL in a specific airplane, but the hope is, eventually, 100LL will be completely replaced by G100UL. The only downside is that G100UL is expected to cost about $1/gallon more than 100LL.
GAMI has partnered with Avfuel, so expect to see 100UL showing up at all Avfuel FBOs in the next year or two.

Yes, you heard correctly. Last fall, Cirrus released a program called Cirrus Embark. The Cirrus Embark program offers 3 Free Days of Training to new purchasers of used Cirrus aircraft. The 3 Days is equivalent to the Cirrus VFR Transition Training Course.
Previously, Cirrus offered free factory training to anyone who purchased a new Cirrus from the Cirrus factory. Now, anyone buying a used Cirrus gets the same offer through Cirrus Embark at their home airport with a local CSIP training provider.
IFR pilot? No problem. The Cirrus IFR Advanced Transition Training Course is 5 days in length, but the Cirrus Embark program covers the first 3, reducing the out of pocket pay to only 2 days.

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.
