The Malibu & M-Class Owner’s and Pilot’s Association recently released their MMOPA Vision Video. It is a great video detailing the history of the Piper PA46 & the history of MMOPA. The PA46 would have ceased to exist without the founding of the original Malibu Coalition.
Checkout the video above (and Texas Top Aviation’s Hank Gibson even gets a cameo!).
What’s the most cost effective glass panel retrofit? There are several options out there (and it seems like more coming each Sun ‘N’ Fun or Osh Kosh event), but the consensus is the Aspen EFD 1000 or 1500, right? At $12,000 installed, it’s about $8,000-$10,000 cheaper than the Garmin G500 (though you can make the argument that when you add a second screen and SVT to the Aspen, the price is about the same).
I am here to blow your mind. What if you could get a glass panel retrofit that is a complete AHRS system with airspeed and altitude, plus a slaved HSI that auto slews to your GPS and a 4 hour backup battery so you can throw your steam attitude indicator away, for only $4,600, plus installation?
I am not crazy.
The Garmin G5 debuted last year when the FAA relaxed it’s regulations to allow more experimental avionics into certified airplanes. The single G5 was a big hit. The 3.5 inch screen fit nicely into the hole that the traditional attitude indicator left, giving pilots a glass attitude, airspeed and altimeter options for less than $2,500.
In March, Garmin brought out the HSI version of the G5. Equipped with a low cost magnetometer, the DG/HSI version is a complete replacement for the traditional DG/HSI. The unit also displays ground speed and distance (received from the GPS information), while auto-slewing to the GPS flight plan, so the CDI needle will move on it’s own, eliminating the annoying need for the pilot to set the course on the HSI (and ridding the GPS of the message that pops up reminding the pilot to set the course).
The dual units provide a complete backup Attitude in the case of a display failure. The reversionary mode you get with the Garmin G1000 and the Garmin G500 is also present in the dual G5s. This eliminates the need for a backup steam gauge attitude indicator, freeing up panel space for an engine monitor or some other toy. The G5 units can also be equipped with 4 hour backup batteries in case of electrical failure.
The price for the dual G5 setup is very reasonable at just under $4,600 plus installation (which, according to Garmin, should be pretty simple as the units act as plug and play instruments). The AHRS unit is available stand alone for under $2,200 while the DG/HSI unit standalone runs just under $2,600.

On March 30th, Texas Governor Greg Abbott issued an Executive Order mandating that all travelers (including Texas air travelers operating or traveling in private aircraft) from the following designated areas were to self-quarantine for 14 days (or the extent of their stay in Texas, whichever was shorter) upon entering the State:
If you traveled to Texas by air from any of the above designated areas, you are required to fill out the Arrivals from Areas Designated for Mandatory Self-Quarantine Form. Failure to do so could lead to a $1,000 fine or 180 days in jail, or both. For private aircraft owners/operators, put your Tail Number in for Flight Number and “Private” for Airline.
Aircraft owners, stay away from the designated areas listed above and you won’t have any worries. A lot of you reading this are from Texas, so make Louisiana a fly over state for now and don’t make any landings in Cajun country.
I get to fly a lot of different airplanes in my chosen career. There aren’t many airplanes that I take off in, then say “Wow,” and have a big smile on my face. The RDD LX7 was definitely one of those.
I wrote about the RDD LX7 in the past, bragging about everything I read about it. The blogs all advertised 250 KTAS and 17 GPH and FL250, all of which are eye popping numbers.
Lo and behold, those numbers are true.
I got to go up to RDD’s Redmond, Oregon facility in April 2021 to get my initial training in the RDD LX7 and I couldn’t wipe the smile off my face. The 3 screen G3X Touch layout is very impressive and not crowded like I thought it would be. Being familiar with the G500TXi, there are some G3X specifics that take a little getting used to, but overall, it’s a good system. The main GPS and number 1 radio is a GTN 750Xi.
We took off from RDM and proceeded to climb at 140 KIAS, which equated to 2,000 FPM. We only had half tanks (which is still 90 gallons of fuel!), but it climbed with no problem. It’s extremely responsive as I learned while doing the basic flight maneuvers. The stall speed of the airplane (the biggest problem with the Lancair 4P, the airframe that the RDD LX7 is derived from, was the terrible wing design and extremely high stall speed), was in the low 60s or high 50s, with the stall being extremely docile.
The airplane handled very similarly to a Columbia 400, but seemed even more responsive. The glide ratio isn’t as good as some, but it’s still better than a Cirrus (plus it still has a BRS system to boot).
The big test was the flight to San Antonio from Redmond to bring the plane home. The new owner and I departed RDM with the tanks full of Avgas (180 gallons), then got up to a cruise altitude of FL210. After setting power and leaning, the numbers came out true to spec: 252 KTAS, 17.5 GPH.
The greatest part? We stopped in Santa Fe to stretch our legs and we didn’t need fuel. We still had 100 gallons left! That left us plenty to get to San Antonio with 40-50 gallons left over. Another RDD LX7 owner flew his piston direct from Redmond, OR to Jacksonville, FL, non-stop. It was over 9 hours. That’s impressive.
You can’t beat the purchase price, either. A new Cirrus SR22T runs a little north of $1.2m. A piston engine LX7, that is pressurized, 70 KTAS faster with a much longer range, and still has a BRS, is between $850,000-$900,000. An LX7 starts to make a whole lot of sense when you weigh all that. There is also a PT6 option with several different sizes and horsepowers to choose from, which costs more, but you see 300 KTAS.

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.
Diamond Aircraft announced in June that the company is going to bring it’s Diamond DA50 RG to market. The company expects European certification in early 2021 and FAA certification toward the end of 2021.
This is not the first iteration of the Diamond DA50, but it is the first with retractable gear. Diamond is known for it’s use of Jet A burning piston engines and you can’t beat the efficiency. The technology in the Continental CD-300 Jet A piston engine is new, but it has been in development for a long time. Diamond advertises 180 knots on only 9 GPH, which is just about as efficient as you can get with a single engine piston.
The addition of the retractable gear from previous iterations of the Diamond DA50 RG is a nice touch. Diamond already had the RG technology from the DA42 Twin Star as well as the more powerful cross country machine, the DA62. Equipping the single engine Diamond DA50 RG with retractable gear just makes sense. It definitely puts the airplane in a class of it’s own.
Diamond’s website shows a nice roomy cabin in the DA50 RG with plenty of space to spread out, plus plenty of baggage. The fuel tanks only hold 50 gallons of Jet A (which still gives a 4 hour + range with an hour reserve at 9 GPH), so the payload, even with full fuel, is an eye popping 897 lbs, though Diamond’s site does not mention if that includes TKS, air conditioning, and oxygen. If it does, then compare that to a fully fueled Cirrus SR22T (which would give an equal speed) at 537 lbs and the Diamond DA50 RG has an argument.
As with all new airplanes these days, the Diamond DA50 RG has the Garmin G1000 NXi complete with keypad and the GFC 700 autopilot with yaw damper. The interior has a 3 person bench seat for the back seat, which, at least to the naked eye, appears that it might actually fit 3 adults, albeit small ones. Diamond’s signature stick in the middle of the seat is still present for the front seats, but the right seat stick in the Diamond DA50 RG is removable for passenger comfort, a nice touch.
The single engine piston market is a hard one to break in to since Cirrus has such a leg up on the competition. However, with a Jet A burning engine, a higher payload, and a roomier cabin, the Diamond DA50 RG might actually be able to make an impact. Look for this bird at Sun N Fun and Osh Kosh in 2021.
The Garmin GFC 700 Autopilot is an amazing machine. Fully digital and fully integrated with the Garmin G1000 glass panel, it makes a pilot’s workload a lot easier, especially in busy airspace.
I train a lot of pilots in airplanes that have the Garmin GFC 700 autopilot. The Cirrus SR22, the Columbia 350 & 400, the G36 Bonanza, and the Piper Mirage and M350 to name a few. The most common problem I see for pilots transitioning into the Garmin GFC 700 equipped aircraft is that it doesn’t act like other autopilots.
STECs and DFC 90 Autopilots function like this: you push the button for the mode you want on the autopilot controller and that turns the autopilot on.
Not so on the Garmin GFC 700. If you push the button for the mode on the GFC 700, then the flight director engages, but not the autopilot. This confuses folks a lot who move up from different autopilots because their autopilot primacy side of their brain is telling them the autopilot is on whenever they push one of the buttons on the GFC 700 controller.
Here’s an example: A pilot has just departed and is ready to turn on course. In his old airplane with an STEC 55x autopilot, the pilot pushes the direct to key to go to his first waypoint, then pushes NAV on the autopilot controller and the STEC 55x comes on and starts flying on course. Then he presses VS and ALT to initiate a climb.
With the same scenario and a Garmin GFC 700 autopilot, the same pilot (who is used to a 55x), pushes the direct to key, then pushes NAV on the autopilot controller and pushes IAS or FLC to initiate the climb. He lets go of the flight controls thinking the autopilot is engaged. The airplane starts nosing over and he starts panicking.
Why did this happen? The pilot in the second scenario never pushed the AP button on the Garmin GFC 700 so the autopilot never engaged. All he did by pressing the NAV button and IAS button was to turn the flight director on.
How to remedy this? Get in the habit of checking your scoreboard. On the top of the G1000 or Garmin Perspective PFD, there is an autopilot annunciation strip (or scoreboard as I like to call it). In the very middle of the scoreboard is an area to show if the autopilot or flight director is engaged. AP means the autopilot is on; FD means the flight director is engaged but the autopilot is not.
I teach pilots to be in the habit of checking your scoreboard each time you get done pressing buttons on the autopilot controller to ensure the Garmin GFC 700 is in the proper mode. This saves some of those panic moments when it is supposed the AP is engaged, but it’s only the FD.
