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.
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:
California
Louisiana
Washington State
Atlanta, Georgia
Chicago, Illinois
Detroit, Michigan
Miami, Florida
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.
A lot of my customers ask me which airplane that I train in is my favorite. The Cirrus and the Columbia both are very good airplanes, but if I had my pick, I’d go with a Piper PA46, specifically an ’86-’88 Malibu.
I love the Piper PA46. 6 seat, cabin class, pressurization, air conditioning, great ramp appeal, 17 GPH (in the Continental TSIO 520 or 550; Piper changed to the Lycoming TIO 540 in ’89, which you run rich of peak and burn 22 GPH, decreasing a little bit of the awesomeness). What more can you ask for? The interior is roomy, there is plenty of baggage space in the nose and in the rear of the cabin. They are downright fabulous airplanes. Plus, you can get into a nice one that has had some panel upgrades and a mid time engine for around $300,000. That’s not bad.
Cessna tried to make a pressurized single with the P210, but it just doesn’t match up with the Piper PA46. The Piper has more room, more baggage space, a higher max differential pressure and service ceiling, and better air conditioning to boot!
Don’t know much about the Piper PA46? It’s been called several things. Originally, it was the Malibu, with a Continental engine. Now the TSIO 520 was not one of Continental’s better motors. However, most of the original Malibus have been upgraded to the much better TSIO 550C engine, which is a great product. Cruise around at almost 200 knots at FL200 and burn only 17 GPH. It’s beautiful.
Piper changed to the Lycoming engine in 1989 and changed the name to the Malibu Mirage, later shortened to just Mirage.
Then, in 2016, Piper upgraded a lot of the avionics, cleaned up the panel, and dubbed it the M350.
Piper made the ill fated decision in the mid 2000s to quit making the Saratoga and instead make an unpressurized version of the PA46 called the Matrix. It didn’t last long, only about 10 years or so, and hasn’t been very popular (see: don’t buy one). Piper took the best part about the PA46, the pressurization, and took it away, leaving an airplane that you still have to wear oxygen in to get the advertised high speeds in the upper teens and flight levels. Who wants to be cruising around in a cabin class airplane with oxygen on? Piper needs to bring the Saratoga back to give folks a low level, high performance option.
What would be my dream Piper PA46? As stated above, an ’86-’88 model Malibu (Piper started off with hydraulic flaps in the ’84-’85 models and it wasn’t a very good system. They changed to electric flaps in ’86) with a Continental TSIO 550C upgrade. The Garmin autopilot isn’t out yet, so I’d go with the STEC 3100 Autopilot w/ a Yaw Damper (the airplane originally came with a King KFC 150, which is a really good autopilot, but most of them are getting old and are getting difficult to fix. King’s replacement KFC 325 is still slogging through certification. Garmin’s GFC 600 would be ideal, but that isn’t expected to be certified for the PA46 fleet till late this year). A single Garmin 10.6″ G500 TXi with EIS tied to a Garmin GTN 750 GPS with a Garmin GTR 225 Nav/Comm as the number 2 radio.
Then I just put gas in it and go. That would be my kind of airplane.
Density Altitude: Pressure Altitude corrected for non-standard temperature.
That’s the book definition of density altitude. The problem is, that definition leaves a lot of general aviation pilots scratching their heads. What really is density altitude?
All airplane engines rely on air and fuel mixing together, then that mixture is ignited to create combustion. Normally aspirated piston engine airplanes get their best performance at sea level, where the air is nice and thick, allowing plenty of air molecules to get sucked in the engine intake. As a normally-aspirated airplane climbs, the ambient air pressure drops with an increase in altitude (the air gets thinner, less dense), thereby reducing airplane takeoff, climb, and landing performance. There just isn’t as much air at higher altitudes, to put it simply.
Turbo charged piston engines assist with this air density problem. A turbo charger boosts the air coming into the engine and fools the engine into thinking it is at sea level pressure all the time. The higher the altitude, the faster the turbo charger spins, spinning the compressor faster, which compresses more air to continue to give the engine sea level pressure air. This gets faster cruise speeds the higher you go.
Both normally aspirated & turbo charged engines do experience longer takeoff rolls and reduced climb rates at higher airport elevations & higher altitudes.
How does this all relate to density altitude?
When the outside air temperature rises, the air becomes thinner, less dense. This means that when an airport elevation is 1,000 feet, but the density altitude is reported as 3,000 feet, the airplane engine thinks it is at 3,000 feet. It won’t accelerate as fast. The airplane’s climb rate will also be reduced. That means that the normal climb pitch attitude a pilot is used to seeing won’t be accurate at higher density altitudes. It will lead to slower indicated airspeeds, slow enough to potentially lead to a stall if a pilot isn’t paying attention.
Where does this get dangerous? High elevation airports. Whenever the OAT creeps above 85 or 90 at an airport that is higher elevation (I would classify higher elevation as 2,500 feet or higher), the corresponding density altitude sky rockets. If a pilot isn’t paying attention to airspeed or angle of attack (if the airplane is equipped with an AOA), a stall can come very quickly on climb out.
What to take home from this? Monitor your climb speed and angle of attack, especially right after takeoff, when you hear density altitude on the ATIS or AWOS.
Texas Top Aviation has added a new member to our instructing team. Stephanie Mertz was hired in March 2019 and will be specializing in G1000 & Instrument instruction.
Stephanie graduated from LeTourneau University in Longview, Texas with a degree in Aeronautical Science, earning her commercial single and multi ratings while there. She began her aviation career in Ontario, California flying a Pilatus PC-12 for charter and medical trips. While operating the PC-12, she gained valuable experience flying all over the US and Mexico.
In 2013, Stephanie moved back to East Texas with her husband where she worked as a contract pilot flying a variety of Citations as well as a Falcon 10. A few years later, she became involved in her local Ninety-Nines chapter and joined their mentorship program.
After earning her CFI, CFII, and MEI, Stephanie returned to her alma mater to pass on her flying passions to college students through flight instructing. After a year of teaching at LeTourneau, she and her husband, with their first baby in tow, moved to the Austin area. Now she is instructing with Texas Top Aviation while acting as a mentor for other women working on achieving their flying dreams.
The first task I give my new instrument students before we start training is to find a view limiting device that they like. There’s the hood that everyone hates (which has been used since the beginning of instrument training,though it isn’t that uncomfortable) or foggles, which usually end up becoming very uncomfortable very quickly. The headset ends up pressing the sides of the foggles into the side of your head, leaving lumps and scars that hurt for days.
Well, there is finally another solution that combines the hood and foggles. Meet the ViBAN.
ViBAN brags that it is the most comfortable IFR view limiting device out there. I have a customer who has one and he loves it. It’s easy to put reading glasses on underneath while still blocking the view of the exterior of the plane. It doesn’t leave bruises against the side of your head, either.
If you’re looking for something different for your IFR training, give ViBAN a try.
A couple of months ago, I had a life-threatening experience while flying. Thankfully, with my flight training, along with a lot of luck, I am here to talk about it.
One of my many piloting jobs is as a glider tow pilot. For those not familiar with gliding, since a glider doesn’t have an engine, every time a glider pilot goes and flies, it’s a team effort. A powered airplane (anything from a Super Cub to a turbine powered Air Tractor) is attached to the glider via a tow rope, which is about 200 feet long. Once the glider pilot gives the go ahead over the airport’s CTAF, then the tow plane begins it’s takeoff roll, pulling the glider along behind it.
The glider becomes airborne prior to the tow plane, then the tow plane will circle the airport environment till it get’s to the pre-determined altitude to release the glider. Some tows are pattern tows and some are higher (not usually above 3,000 AGL), depending on the request from the glider pilot. Once the altitude is reached, the glider pilot pulls a handle in the glider to release the tow rope, then begins his glide. The rope stays attached to the tail of the tow plane, which in turn descends back down to the runway and lands. The tow plane also has a tow rope release handle in case of emergency.
On this particular tow, the plan was to tow the glider up to 3,000 AGL. Upon reaching 2,500 AGL, the glider pilot called me on the radio and stated that his rear canopy had opened up. I looked over my shoulder and sure enough, the rear canopy was fully opened while he was still in level flight behind me. I asked him if he wanted me to tow him closer to the field, but he didn’t reply.
Now, as an experienced tow pilot, I know a glider canopy popping open should not be an emergency situation. It’s definitely abnormal, but would be similar to a door or window popping open in a powered airplane. Not a big deal. If too much force from the relative wind is applied to the canopy, it would snap off; however, a glider can easily land without a rear canopy.
About 5 seconds after I radioed the pilot (and received no reply), I felt my tail instantaneously lift up into a completely vertical position, which caused my nose to go straight down. The next thing I knew, a whole lot of earth suddenly filled my windscreen and I was in what’s known as a graveyard spiral.
A graveyard spiral (as defined from the Airplane Flying Handbook pg 4-23), “is a descending turn during which airspeed and G-load can increase rapidly….the airplane is flying very tight circles, in a nearly vertical attitude and will be accelerating since it isn’t stalled.” It’s also known as a spiral dive.
Back to the story. At this point, I tried to reach for the glider release handle. Unfortunately, due to the shoulder straps holding me against the seat, plus the g’s, and also the quart of oil and tow bar that flew forward and hit me in the back of the head, I couldn’t reach it. I was semi-upside down at a certain point, which dislodged the oil and tow bar from the floor of the baggage compartment. They sailed over the seat and nearly gave me a concussion.
At this point, 2,500 feet above the ground, I had a choice to either fight for my life at a very low altitude or to sit back and become part of a big explosion.
I decided to fight for my life.
As I was spiraling to the ground, I felt the tow rope snap. Up to this point, I had still been attached to the glider. The rope snapping was a good thing, as my airplane was now under my control, not attached to, and being affected by, a glider (more on that later). I now had a lifeline, no pun intended.
After I felt the rope snap, my instincts and training kicked in. I initiated the spin recovery procedure using the PARE acronym. This task was difficult to do as I had a lot of debris flying from the rear of the plane to the front, blocking my view out of the windshield. There was also debris around my feet, hampering my ability to use the rudder pedals. The spiral finally stopped and I recovered approximately 500 feet above the tree tops. It took my heart a lot longer to stop spinning.
After barely regaining my emotions, I tried to evaluate the condition of the plane. Were all the pieces of the plane still there, was the engine damaged, did my control surfaces still work?
Once I advanced the throttle and saw an increase in my engine RPM, I started an immediate climb to give me altitude to get back to the airport. I had engine power but I wasn’t sure how long it would last if I had damage. Now, what they don’t teach you during spin training is that when this happens unexpectedly, you will become very disorientated. You have just been spiraling unexpectedly and your equilibrium will be out of whack. As I leveled out just over the tree tops, I was too low to visually see any landmarks, nor could I see the airport. Once I was able to climb, I was able to orient myself and figure out where the airport was.
I had to be very careful getting back to the airport and landing without radio communication, since my radio was knocked out with all of the FOD from the baggage area. Thankfully, the landing was uneventful. After I landed, I saw the glider limp in over the trees. The rear canopy was totally gone, while the front canopy and other parts of the glider had suffered major damage. Miraculously, my airplane wasn’t damaged, except for the wire from the radio which came loose during the spiral.
So, how did all this happen, you ask? Well, the glider pilot made 2 huge mistakes. First, in gliding, the moment the glider pilot loses visual sight of the tow plane, you are supposed to release the tow rope. He did not do that and almost killed both of us.
Second, as pilots we are taught to always fly the airplane first. Everything else, no matter what it is, always comes after flying the airplane. As I stated previously, the loose canopy is not an emergency situation, but since the glider pilot did not aviate first and was distracted, it was almost a fatal day for 2 people and 2 airframes.
So, what caused this chain of events? By getting distracted by the open canopy, the glider pilot inadvertently pulled back on the stick while trying to close the canopy. Then, by not releasing the glider from the tow plane, the glider pilot climbed rapidly with an excessive rate of climb while still being attached to me. The rapid climb is what pulled my tail up, causing my nose to drop and put me into the spiral. The tow rope snapping set into motion my recovery, since up till that point, I literally had no control. An extremely high lift wing was attached to my tail, pulling it up, and there was absolutely nothing I could do about it.
We all spend time practicing and demonstrating emergency maneuvers during our flight training and during flight reviews. Many times you might think, I’ll never need to use this stuff. Thankfully, some of the procedures I learned in the past kicked in at a time of need, even though my heart was beating out of my chest.
At some point in every pilot’s career, some type of spin training or Upset Recovery Training would be highly recommended. Then, when things go wrong, remember to always aviate first, then handle all the other things that need to be handled.
