AOPA recapped the year in the general aviation industry recently. A lot happened in 2016 including the certification of both the Cirrus Vision Jet and the Honda Jet. Several other manufacturers debuted new models, including Mooney with their Ovation Ultra and it’s 2 doors and Cub Crafters with their faster XCub.

I’m sure at this point, most pilots in Texas have heard about the Cessna 421 that went down two weeks ago in Lufkin. The Golden Eagle suffered a dual engine failure (the pilot lost the first at 2300 feet, then the second at 1700 feet) in IMC on climb out. He broke out at 1,000 AGL miraculously lined up with US 59, south of the Lufkin airport. The pilot had to dodge a car as he was attempting his landing, stalled the airplane, sheared off the landing gear, then slid into the median. No one died, but lots of bumps and bruises. All were airlifted to Houston.
The cause was a lineman at LFK put Jet A in the 421, which is a piston airplane and takes 100LL Avgas. The story that I saw said the pilot and two passengers were returning to Houston from Kansas City and diverted to LFK due to weather. They landed in driving rain and spent the night. I have not seen any reports saying whether the pilot sumped the tanks or not the following morning.
There were several factors that led to this accident. If you take one factor out, the accident probably wouldn’t have happened. Let’s take a look at the sequence of events.
The 421 arrived in a driving rain storm, so the pilot and passengers probably disembarked quickly to get out of the weather. Factor number 1 presents itself here. We don’t know whether or not the pilot told the lineman to put Avgas in it or not (he may have just said fill it up), so we’ll leave that aside.
Understandably, the pilot dashed inside to get out of the rain, but they neglected to monitor the fueling. Whether or not the fueling took place that night or the next morning, we can’t say. I have started to greatly encourage my customers to monitor the fueling of their airplanes, especially when it’s a fuselage that can either have Avgas piston engines or Jet A turboprops, as is the case with the Cessna 421.
Factor number 2, we already know about. The lineman messed up and put the wrong fuel in. If their was uncertainty about what type of fuel, he would have been prudent to await the return of the pilot to ask, even if that meant delaying the pilot’s departure.
Factor number 3 is the matter of sumping the fuel. We don’t know if the pilot sumped the fuel or not. The tricky thing about sumping is Jet A doesn’t settle out of Avgas like water does unless it sits for a long, long time. The two ways to determine if you have Jet A in your Avgas airplane are to smell it, as Jet A has a very strong diesel smell, or do the paper towel test. The paper towel test consists of dumping a fuel sample onto a paper towel, then let the Avgas evaporate. If you are left with a nasty, oily residue, you’ve got Jet A in your tanks (not to mention it will smell like diesel).
To prevent misfueling of your airplane, take the following steps:
Some of a pilot’s favorite words are heard on the ATIS: “Winds, Calm.” These words set off all sorts of happy bells and hallelujah choruses. Most pilots spend their lives fighting the winds. On those rare days when the winds are calm, great happiness ensues.
But, are calm wind landings more complicated then everyone thinks? Well, they can be if the proper planning doesn’t go into them.
Let’s think about wind. We have surface wind and we have winds aloft. Sometimes the surface winds are calm. When this happens, certain airports have preferred calm wind runways which are supposed to be used in these conditions. Winds aloft are almost never calm. 95% of the time, there is some kind of wind even 100-200 feet above the surface.
Here is the question pilot’s face when coming into an airport with calm winds: which runway do I use? Do I use the calm wind runway? Do I use the runway that is easiest to enter the pattern for? Do I use the one with the shortest taxi?
A lot of technologically advanced aircraft have a wind indicator on the PFD. This tool is often forgotten in calm surface wind conditions. On the contrary, this is probably the most important tool a pilot can have when figuring out which runway to use when the winds are reported calm.
Here’s why. That wind indicator is showing the pilot what the winds aloft are. The winds aloft should determine what runway is going to be used. If the wind indicator is depicting a south wind, then a south runway should be used. Even if it is a 5 knot wind at pattern altitude, it’ll still be a headwind coming in on final approach. If the north facing runway is used, that same 5 knot headwind can blow an airplane halfway down the runway before the ground speed drops off enough for it to land.
So, the next time you are coming into an airport and the winds are reported calm, take a look at your wind indicator on your PFD when deciding which runway to use. It’ll probably save a few go arounds!
You are hand-flying an in-the-weather descent, power back, heading for the FAF. You start a 30 degree banked turn at your lead point to cross the FAF, when your passenger behind you gasps. Looking over your shoulder, you see he has spilled his drink into his lap…too bad for him! However, when you turn your head back to your panel, your inner ear tumbles and you see 45 degrees of bank, 15 degrees nose low, airspeed increasing.
Congratulations! You have managed to get distracted and sucked into an unusual attitude recovery. By the book, you should roll wings level, pull to the horizon, and adjust power as necessary to keep the airspeed within limits. In this scenario, if you had not experienced vertigo, you might have been able to roll to less than 30 degrees of bank, recover your turn, pull the nose up to less than the original descent attitude, pulled a bit of power to slow back to your desired penetration speed and then resumed your desired ground track. However, this would only be appropriate if you had full situational awareness as to the deviations caused by the look over your shoulder, plus full confidence that the moderate corrective actions would put you back on your desired flight path.
As a military aviator, I learned unusual attitude recoveries based upon hard maneuvering at extreme pitch and bank angles. In the hard-maneuvering environment, an unusual attitude could be 90 degrees straight up, airspeed decreasing below 120 kts…or 80 degrees nose low, 135 degrees of bank, airspeed increasing through 500 kts… etc. In these cases, understanding angle of attack, or AOA, is critical to maintaining controlled flight and returning to a normal attitude.
In an extreme nose-high attitude, a military aviator is trained to roll the aircraft to 90 degrees of bank, ease off the back-stick pressure to reduce AOA, add power as required, and allow the nose to slice back towards level, rolling to wings level as the nose approaches the horizon. If nose low, the recovery procedure is to roll rapidly, within asymmetric g limits, until wings level, then to pull at optimum g loading to recover to level flight. For the nose-low recovery, power was normally reduced until airspeed could be assessed and brought under control. However, when doing the nose-low pullout at 7-9 gs, pulling the power for too long would leave you much to slow to resume combat.
The AOA gauge on a fighter’s glare shield is a primary reference during hard maneuvering and for landing. The AOA for optimum maneuvering is 13 degrees, displayed as the green circle or “green donut” on the gauge. The red chevron on top represents a slow condition of 15 degrees or more and the yellow lower chevron represents 11 degrees or less.
For normal landing in the F-16C, the pilot slows to 220 kts and configures abeam the touchdown point while mentally computing the final approach airspeed of 136 kts plus 4 additional knots for each 1000 lbs of fuel. When rolling off the perch and flying the final turn, the pilot would usually only glance once at the airspeed once to ensure final turn airspeed of 180 kts while using the AOA sight gauge as the primary indicator of a best performance turn. As long as the AOA was green donut (13 degrees) or less, you would not stall. If on speed and 13 degrees wasn’t going to get you around the turn to line up with the runway, you knew you were going to overshoot. You never wanted to see the red chevron of 15 degrees or more as that meant you were too slow, pulling too hard, and in danger of building an un-recoverable sink rate!
Few GA aircraft are currently equipped with AOA indicators, though there are several after market devices available for retrofit. However, knowing the impact of AOA and how to manage it is vital to safe aviating, even without an AOA gauge. The bottom line is, as long as you don’t ask the wing to produce more angle of attack than it can handle, you won’t stall.
Practicing final turn stalls, to know what the wing feels like as you get too slow or pull too much on the controls, increasing AOA past the critical point, will keep you safe when you encounter that unexpected overshooting wind or you find yourself inadvertently on too tight of a downwind leg. Better to overshoot or take it around to try again, than to pull too hard and exceed critical AOA.

I’m a big fan of having my Foreflight map always match up exactly with the way I am flying. Having a Flight Stream in the airplane helps a lot with that as it always prompts me to load the new flight plan from the GPS into my Foreflight map. When I load an approach in the GPS flight plan, Foreflight will put it into my Foreflight flight plan via the Flight Stream.
The problem I run into on Foreflight is when there is a published hold at the Initial Approach Fix (IAF), but ATC has told me to fly the straight in approach and skip the hold. Up until recently, I didn’t think there was a way to set up a straight in approach on Foreflight, so I just settled for the hold staying on there.
Not anymore! There is a simple trick that I discovered that allows you to remove the hold from the Foreflight flight plan. Here’s how to do it.
The first step is still to load the approach into your Foreflight flight plan on the Map page. In this scenario, we are flying from KAQO, the Llano Airport, to KHYI, the San Marcos Airport. Austin Approach has told us to expect the straight in RNAV 17 KHYI via PUKIY. So, on Foreflight, we have KAQO and KHYI in our flight plan. Then, I tap the Procedures button on the upper right hand corner of the screen. I then tap Approach, then RNAV 17 KHYI. Then I select my transition.
The options given are either PUKIY with the hold, seen below;
Or Vectors to Final, which lines me up inside of PUKIY. Neither of these are what I want.
But, to get this to work, I select PUKIY, then tap add to route. Now we have our approach loaded into our flight plan.
The RNAV 17 is now in the Foreflight flight plan, but the hold is displayed at PUKIY. To remove the hold, the first step is to tap the approach in green and a menu pops up.
The 7th option down is “Remove Hold in lieu of PT.” Eureka! Tap that, then the approach is displayed without the hold. Houston, we have success! It even says “NoPT” in the flight plan.
I was recently clued in to a really cool (and very cost efficient) iPad yoke mount.
It’s called a PopSocket and you won’t find it on any aviation website (I have to credit Joe Casey of Casey Aviation with this nifty find).
It’s very simple. You take the mount (see right) and stick it to your yoke. Then you pick one of a ton of designs from PopSocket and stick it to the back of your iPad (you can even create your own design! B2 Bomber anyone?).
It’s low profile, doesn’t get in the way of anything, and is easily removable. The PopSocket mounts are $10 apiece (depending on the size of your iPad, you may want to get 2). The PopSocket is $10, so at the most, you’ll be in $40 plus tax and shipping. Most mounts on Sporty’s are upwards of $50 and require a lot of installation, are big and bulky, and usually require lots of juggling to get the iPad in and out of the mount.
Give the PopSocket a try.
