Late last year, the Diamond Aircraft Corporation announced a brand new twin engine, the Diamond DA62. At first glance, this is a pretty cool airplane. It seats 7 passengers, spread out amongst 3 rows, with 2 massive doors, leading to an “SUV” type feel, according to Flying Magazine. That is only one of the “neato” features of the Diamond DA62.
The thing that will make pilots believers is the fuel burn. According to Flying Magazine, which did a test flight of the airplane, at 14,000 feet and 60% power, the airplane was only burning 12 GPH, but still doing 170 KTAS. Remember, this is a twin. That’s about the same as a normally aspirated Cirrus SR22 at the same altitude.
How does Diamond do it? Jet A. The company put two Austro AE330, 170 Horsepower, Jet A burning piston engines on the Diamond DA62. You may say, well, yeah, at 60% power, that’s great, but I want to go places. How much fuel does it burn then? Even at max continuous power of 95%, it’s still only burning 18.5 GPH total and cruising at 195 knots. Paying Jet A prices, that’s pretty sweet.
The range on the airplane is quite nice too. Again, according to Flying Magazine, the range with full fuel (86.4 gallons with aux tanks) is about 1,300 miles. You can carry the whole family too, as the full fuel payload is 1,000 pounds. Golf clubs? No problem. Just stick them in the nose.
The Diamond DA62 is probably one of the easiest twins to manage, engine-wise, too. The Fully Automated Digital Engine Control (FADEC) system that Diamond installed leaves the pilot with only 2 power levers, instead of 6 on the typical piston twin. All that needs to be done at cruise is set a percent power and the FADEC computer does the rest.
Need air conditioning, built in oxygen, and TKS? Diamond can set you up. The G1000 system complete with digital backup instruments is standard in the airplane. What more can you really ask for?
If you haven’t figured it out, I really like this airplane and would be aching to fly it. I enjoy the DA40 and have a good amount of DA42 experience, but I’d really like to hop in a Diamond DA62.
When I was doing my instrument and multi-engine training, we did a lot of circle to land approaches. As a student, I could never figure out why these types of approaches would ever be practical when you could an approach straight in to another runway. But, as a good student, I never asked my instructors the purpose of them, I just did them to the best of my ability.
Now, having been flying in the IFR system for almost a decade, I’m finally beginning to fully understand the practical purpose of a circle to land approach. I have actually elected to do an approach where I had to circle to land on several occasions in actual IMC conditions.
One important note to remember on circle to land approaches is that the minimum descent altitude (MDA) is always higher than on a straight in approach. The reason for this is that you are basically joining the pattern for a different runway and you have to be able to visually keep yourself clear of towers and other obstacles. So, you need a higher visibility and a higher ceiling than if you were just lining up to come straight in.
Here are a couple of practical circumstances where it would make sense to do a circle to land approach.
Airports with only 1 straight in approach
This one is easy. There are a number of airports scattered around the US that have only 1 straight in instrument approach published for it. Around my part of Texas, the first one that pops into my mind is the RNAV 31 at T85 in Yoakum, TX. Most of the year, the prevailing wind is out of the south, so 13 is the favored runway at T85. During the winter is when most of the IMC weather happens in South Texas, so that is why the approach is for 31.
Of course, especially this year during the summer, there are some IMC days where an approach to T85 would be necessary. When there is a strong wind out of the south, landing on 31 is impractical, so a pilot would fly the approach to 31, then circle to land on 13.
Approaching from the opposite direction
Take a look at the RNAV 19 at KBMQ, Burnet, TX. The two initial approach fixes (IAF) are IXANY and JIBAJ. If a flight is approaching BMQ from the west or north, this is an easy approach to join. If a flight is coming from Austin (directly the the east and a little south) or San Antonio (almost directly south), it would be a bit of extra flying to get configured properly for the approach. Especially coming from Austin, because the degree of turn to join at JIBAJ wouldn’t make the approach practical.
Well, how about vectors? Unfortunately, Houston Center doesn’t have this approach depicted so vectors aren’t a possibility. Center can give you vectors north to make the angle a little easier to join at JIBAJ, but they can’t vector you onto the approach.
Direct DLORA to join is another option, but again, if you are approaching from the southeast, the angle is wrong.
Insert the RNAV 01 approach with a circle to land. AMUSE is right on V163, so it’s really easy to join the approach there coming from the south. Coming from Austin, joining the approach at SUBIE works out great. Fly down to the MDA, join the left downwind for 19, and everyone is happy.
VOR Circle to Land Approaches
Every instrument pilot has had an instructor “force” them to do a VOR A or VOR B approach and no one enjoys them. I personally think they are good practice. With the number of RNAV systems and RNAV approaches out there, though, VOR approaches are becoming a bit archaic.
They do have a place in this discussion, though. A VOR approach is given an A or B designation when the angle of the final approach course is greater than 30 degrees to the runway (VOR A KLZZ), or the final approach course is lined up with the runway, but the MDA is too high to practically descend and land (VOR A KGRK or the VOR/DME C KASE).
So, there are practical uses for a Circle to Land approach. The next time you do some IMC work with an instructor, ask him/her if you can include one.
When I was doing my instrument and multi-engine training, we did a lot of circle to land approaches. As a student, I could never figure out why these types of approaches would ever be practical when you could an approach straight in to another runway. But, as a good student, I never asked my instructors…
Flying a missed approach can be stressful enough. When you haven’t done one in a while and your GPS isn’t showing you how to get to the missed approach point and you can’t remember which button to press, that adds a lot more stress. Recipe for disaster? Quite possibly!
No need to fear, we are here to help. The procedure for getting a Garmin 530 or 430 to give you missed approach guidance is actually simple and straightforward, if you know what to do!
Note:Because of the variety of different autopilot configurations in different airplanes, this article will focus solely on the GPS.
What the GPS is Thinking
The way Garmin designed the Garmin 530 and Garmin 430 is to be as helpful to pilots as possible. Their thinking was, 95% of the time, a pilot will make a landing on an instrument approach. This is pretty accurate as most of the time, this is what happens. Most general aviation pilots don’t fly approaches to minimums all that often, thus negating the need for a missed approach.
Garmin designed their software with this in mind. When an airplane crosses the missed approach point, the GPS will go into what’s called suspend mode (a SUSP annunciation appears above the OBS key). It will keep the missed approach point as the active waypoint because it assumes the pilot is going to land.
This can be confusing to pilots. This is what happens when software engineers and pilots come together. Engineers often believe they are smarter than pilots! (See the Airbus fly by wire roll out)
The Procedure
In the case of a missed approach, the button pushing on the GPS is actually relatively simple. There is no SUSP key to take the GPS out of SUSP mode (thanks Garmin!). Instead, you press the OBS key. This will take the GPS out of SUSP mode, making the first waypoint on the missed approach procedure the active waypoint. Your GPS will now give you guidance on the missed approach procedure.
If you are going missed off an ILS, LOC, or VOR approach, then there is one more key you’ll have to press. Your CDI needle (whether it is digital or analog, an HSI or just a CDI gauge) will be reading off the NAV radio and your CDI indication on the GPS will be VLOC. After you press the OBS key, press the CDI key on the GPS so you will start getting course guidance from the GPS again.
That’s it. Button pressing on the different autopilots will vary, but if you are familiar with yours, you’ll be able to tell it to follow the GPS and climb to the proper altitude.
Flying a missed approach can be stressful enough. When you haven’t done one in a while and your GPS isn’t showing you how to get to the missed approach point and you can’t remember which button to press, that adds a lot more stress. Recipe for disaster? Quite possibly! No need to fear, we are…
MMOPA will be hosting it’s second Safety Standdown event at many locations across the country for Piper PA46 owners and pilots. The first iteration of MMOPA Safety Standdown in the fall of 2019 was a big hit. Each event was very well attended by MMOPA members.
What is Safety Standdown you ask? Safety Standdown was put together as a mid-year training event as part of the MMOPA Master Aviator program. It’s goal is to allow PA46 owners and pilots to fly in to a location at a reasonable time (the event starts at 10am local time), received some good quality ground training over relevant safety topics by highly experienced PA46 instructors, have a free lunch, then depart mid-afternoon to arrive back home before dark.
The event is free to all attendees. Lunch will be provided at each location. This event is not exclusive to MMOPA members, either. Any PA46 owner or pilot, or just anyone interested in the PA46 world, are invited to attend.
Texas Top Aviation is hosting the South Central Region Spring Safety Standdown at the Henrickson Jet Center at the Austin Executive Airport (KEDC). Hank Gibson and Pedro Vargas-Lebron will be presenting on the following topics:
MMOPA Operational Practices review and importance of stabilized approaches
Crosswind Takeoffs and Landings
High Density Altitude Operations
A discussion of thunderstorms, resources in the cockpit for weather avoidance, and accidents that have occurred involving thunderstorms
The MMOPA Spring Safety Standdown will take place on Saturday, April 18th, 2020. Registration is required for the event. The link for registration can be found here.
Come on out for some high quality training and free BBQ with 50 of your closest PA46 buddies!

When cleaning airplanes, the majority of people don’t know how to properly maintain their TKS panels. TKS panels provide wing leading edge, horizontal stabilizer leading edge, and, in the case of FIKI airplanes, vertical stabilizer leading edge de-icing protection. For those not familiar with them, they are metal strips that have thousands of holes drilled into them where the TKS fluid seeps out. They have become quite prevalent on Cirrus aircraft, the Cessna TTx, and Mooney aircraft manufactured in the last decade or so. The system is also known as a weeping wing system.
Being on the leading edges, these panels pick up bugs very easily. For the uninitiated, it would make sense to just use normal airplane cleaner to spray the panels and scrub the bugs. Don’t!
Using anything that contains Methyl Ethyl Ketone (MEK) as that can harm the TKS bladders behind the panels. Any aircraft cleaner containing wax could cause the pores to clog, preventing the TKS fluid from properly seeping onto the wing.
What’s the best thing to do? Soap and water with a soft cloth is a good start (again, make sure it doesn’t have wax in it. Dish soap would be suitable). No hose available? Just simply turn the TKS system on, let it run till you start to see fluid drip off the wings onto the ground, and use the fluid to clean the panels.
A soft cloth would work fine, but, if the panels are really buggy, take a green scouring pad to do some scrubbing. Just make sure the scrubbing motion is up and down with the grain, not side to side. You can find the green scouring sponges on the dishwashing aisle in the grocery store. Just leave one in the hangar for when you need it.

When a pilot first glances at the title of this article, the first thought that probably goes through that pilot’s head is, well that’s easy.
And it is, if you are flying a high wing Cessna. On other airplanes, there are a few tricks to checking the stall warning horn. If you get them wrong, you’re liable to get a bill from your maintenance shop for an hour of labor for a problem they couldn’t duplicate.
Cirrus SR22
Let’s start with the Cirrus. On the pre-FIKI Cirrus aircraft, there was a small little hole in the wing that contained a diaphragm. That diaphragm sensed a change in airflow at a certain angle of attack just below the critical angle of attack and set off the stall warning horn. Unfortunately, the only way to check that is to suck on the hole during pre-flight.
I don’t. I verify the hole is clear and that’s about it.
On the FIKI Cirrus aircraft, there is actually a stall warning vane. It looks like a high wing Cessna vane, but if you turn the batteries on and try and get it to come on during your light and pitot heat check, nada.
Here’s the trick, and the checklist doesn’t do a good job of describing this.
Turn on the Avionics Master
Turn on the speaker
Put the flaps to full
Then move the stall warning vane and you’ll hear the horn
The speaker and the Avionics Master are so you can actually hear the horn (if you had the headset on while you were doing this, the speaker would be unnecessary). The flaps have to be full because the pitch attitude for the critical angle of attack is lower with the flaps down, so the horn goes off when at a different angle. You then don’t have to use as much force to push the vane.
Piper PA46
The early -310P Malibus are pretty simple and straight forward. Move the vane, get the horn.
In the -350P, you can’t get the horn to come on by moving the vane. So, Piper put a stall test button that’s hidden underneath the upper left side of the instrument panel. Push that to test the horn. On the G1000 PA46, it is located directly above the PFD. On the Avidyne, it’s below and to the left of the pilot’s yoke.
Testing the stall warning horn is a very important part of pre-flight. A pilot needs to know if the aircraft is close to a stall. The advent of Angle of Attack indicators in small, GA aircraft, have added a greater awareness to the angle of attack during all phases of flight to avoid those stall spins.
If the stall warning horn goes off or the AOA shows yellow, lower that nose immediately.

I love cross country flights. Airplanes are designed to travel. When I was instructing private students, my favorite lessons were always the first cross country flights. I looked forward to getting my students out of the pattern, away from the practice area, and showing them what they could really look forward to as a private pilot.
When I was in college, my friend and I borrowed his dad’s Cessna 150, did a cross country flight in it from Indianapolis to Kitty Hawk, then down the coast to Florida. We camped in the grass next to the airplane wherever the airport managers would let us and had our own aviation adventure complete with mechanical problems, unexpected weather, and interesting people along the way. These types of trips have produced some of the best memories and experiences that I’ve acquired during my aviation career so far.
Unfortunately, I know many people whose only cross country flight experience is what was necessary to satisfy their Private and Instrument training requirements. Some of them are nervous about the idea of venturing away from the familiarity of their home airport, while others are relatively new pilots who simply don’t know where to start planning a long cross country flight.
I’ve taken some notes on my preparations for an upcoming cross country flight that I’ll be flying in my dad’s Bonanza. I’m hoping this checklist might help others feel a little more confident that they have everything they need to get going.
Oil
Its always a good idea to bring a few extra quarts of oil. If you stop somewhere and find you need some, its nice to have the right kind on hand. Never assume that the airport you’ll be landing at next will have oil available.
I like to keep a few extra quarts of 15W50 in the back of the Bonanza, just in case (photo from oil-store.com)
Fuel Stops
Here is an example of the 100LL price tool as seen on the Foreflight maps page
I’ve learned the hard way that calling ahead to verify fuel availability can be extremely important. I landed at an airport in Ohio one beautiful Sunday morning to find that the FBO wouldn’t be open until much later in the day. Naturally, there was no other fuel available on the field. I hadn’t called ahead to verify the hours of fuel availability (I assumed they had Self Serve) and had only 2 options: wait a while for the FBO to open, or try and find somewhere else nearby that had gas. As far as price, www.100LL.com is a valuable tool for finding cheap fuel. Foreflight also has posted prices for 100LL and Jet A, but it’s still a good idea to call ahead and verify price and availability.
Batteries for electronics
It’s miserable to run out of batteries for a noise canceling headset with hours remaining in your flight. Bring spares, not only for your headset, but for your flashlight and other gadgets as well. Make sure your hand held GPS, iPad, and Stratus are charged (if you have them). I like to carry a charge cable and adapter as a backup so that I can plug things into the cigarette lighter.
Jumper Cables
We always carry the ground power cable in the back of the Bonanza just in case we ever need a jump. Last month, when I was flying down to Texas, I was glad I had them; we had a dead battery after our fuel stop and had to borrow some power from an FBO worker’s pick up truck. Don’t assume that wherever you are stopping will have the correct cable to jump your airplane, especially if it requires a specific plug.
These are the cables we keep in the back of the Bonanza (photo from airchief.com)
Parking Fees
Every airport is different. I like to call ahead and find out how much the FBO is going to make me pay in landing/overnight fees. When I flew up to Buffalo last summer, I paid 25 dollars for parking at Niagara International (IAG). Had I parked at Buffalo (BUF), they would have charged me over $200.
Approach plates and charts
Make sure you have current approach plates and charts either physically available or downloaded before you blast off. Having a copy of an AFD is a good idea as well, be it digital or paper.
Rental cars
If you arrange it beforehand, many FBO’s will have the car ready for you upon arrival. You may also be able to drop the car off at the FBO when are finished, instead of taking it back to the rental agency. It sure is nice to have the car pulled up next to the airplane when it’s time to unload.
Hotels
Bigger FBO’s may have discounted rates with local hotels. If you call the desk and explain your needs they may offer to book it for you, or at least point you in the right direction. It may be worth picking an airport with more expensive fuel if it puts you closer to the hotels or restaurants you want to go to.
