Commercial Maneuvers and Cross-Country


This is a regular blog post. If you’re looking for show notes or links to show audio, please check out the other entries.

2.5 yesterday KPTK-KMBS-KPTK. I’m seriously considering the commercial certificate, but I have very little PIC cross-country time to places more than 50 nm away. Partly because I got my instrument rating under Part 141, which doesn’t require PIC cross-country time. So I started the day with 22.6 and ended with 25.1.

Even if I’m just going to go out and maneuver, I’m making a real effort to try to touch someplace more than 50 nm away every time. That usually means Saginaw (KMBS). The weather tends to come in longitudinal fronts so, if it’s clear at Pontiac, there’s a decent chance that it’s clear on the way to Saginaw. Or at least a better chance than there is that it’ll be clear somewhere to the west. (I have no problem with east as a cardinal heading, but east for me is Canada and the attendant administrative hassles.)

There was a huge 80 to 100-mile wide cloud deck centered on Saginaw, but it was at least 5,000 feet AGL, which allowed us to fly 4,500 MSL on the way up and 5,500 MSL on the way back. Shot the ILS Rwy 23 and did a pretty decent job of it.

This is also my third flight in the 172RG. I’ll have the 10 hours of retractable time required for the commercial done in the next flight or two, but I think I’ll probably fly this aircraft for the checkride (whenever that happens), so I have no problem getting a lot more time in it.


The other objective was to go see the commercial maneuvers and, in particular, chandelles, lazy eights, steep spirals, and eights on pylons. We haven’t has ceilings that would allow for these maneuvers on any of my prior scheduled flights this year in the RG, so I was really pleased to finally get to do them.

As many of you know, I’m not a natural pilot. I’ve had to really work hard to get the maneuvers right. The instrument rating was easier for me than the private, believe it or not. I just don’t have a good kinesthetic sense. Or at least not the kinesthetic sense of the 23-year-old CFIs with whom I so often fly. Punks! (Extraordinarily talented punks that I greatly admire, by the way.)

So I was really pleased by my performance yesterday. Yeah, I have some polishing to do on a lot of the maneuvers, but I actually flew them reasonably well! I think I love lazy eights. Everything changing in all three axes, but changing at rates and with relationships that you command. And Chandelles are just plain majestic on a cold day when you get really nose-up and climb with brute strength.

Maybe I got the kinesthetic sense after all in a weird way when attitude instrument flying finally clicked for me. I do attitude instrument flying very well and maybe the hood made me pay attention to what was going on empirically (according to the gages) so that I can nail stuff like that now VFR. Even with the distraction of a view out the window!

Anyway, I can see a lot of trips to Saginaw in my future, as well as training for the commercial maneuvers. I have a lot of time to build before I’m qualified to do the checkride, but hey – it’s flying. Please don’t throw me in that briar patch!


The obligatory CFI shot. Meet Dale. He’s a graduate of Western Michigan University’s aviation program and flew well on the commercial demonstrations.

This is the thi9rd different CFI I’ve had in three flights in the RG. Everyone’s a little different in terms of how he or she flies and teaches and that’s fine. But I need to come up with my own checklists and flows for this aircraft.

More than once I had an issue with the gear. Nothing huge. I don’t think that I would have landed gear up. But nearly-as-stupid things like wondering why climb performance sucked so badly after recovering from eights on pylons and heading for home. And then having Dale remind be that we could bring up the gear if we didn’t want to dangle them all the way home.

I do fear the gear-up landing. For myself, I know that mistakes like that are usually task overload. And the best thing for that is to have checklists that I understand and that I can run every time. I think I’ll clear up the gear thing and lots of other issues (prop, carb heat, clearing the engine, and other things that I missed at various times) when I can really sit down with all of the information I’ve received from those with whom I’ve flown the RG and put together my own checklists.

Dale had a particularly good flow. Red, blue, green. Red for the mix, blue for the prop, and then green for the gear-down light (and look out the window for a wheel). Probably easier to remember than GUMPS for that airplane. Anyway, I’ll integrate the best of the pest and go from there.

CAP Form 5 for round-gage instruments scheduled for Sunday at Ann Arbor (KARB). I’m going to go back to DCT Aviation and fly some sim on Saturday to prepare, but I think I have a pretty good chance of passing. We’re flying a C-172R, N992CP (CAPFLIGHT 2028) and CAP SM Scott Gilliland will also be doing his VFR Form 5 that day.

As you might recall, I got Form 5′ed VFR-only in August. They had a C-172P for the check with a panel that I’d never flown. I didn’t want to try to do a full-up instrument checkride on a strange panel, so I elected to go VFR only. Now that I have the chance to fly a C-172R (in which I have something like 80 hours in model and five hours in this particular aircraft), I feel good to go for the instrument ride. It has an Apollo GPS, which which I have only the most rudimentary VFR experience, but we’re not going to be flying any RNAV approaches. Still, I like having the instrument approach overlays for situational awareness and I need to get through the manual before Sunday to see if I can get that part down.

I did the weight and balance and, as long as we launch with 30 gallons of fuel or less, we can probably fit all three in the aircraft. Might be cool. I haven’t ridden in the back seat of a C-172 since I was a kid. Might be nice to see someone else fly for a change. Of course, that means a peanut gallery for my part of the ride, but Scott’s a good guy and will probably remember to reposition his mic before laughing out loud.

Administering the ride will be check airman Capt Alex Craig, who has solid aerobatic and other credentials and flies a Bonanza when he’s not serving with CAP.

As always, I enjoy objective tests of my pilot skills. And a CAP Form 5 check is always a worthy test.

Spatial Disorientation Simulator

These are the show notes to an audio episode. You can listen online right here by clicking: http://media.libsyn.com/media/airspeed/AirspeedSpatial.mp3.

I spent some time recently at the Great Lakes Aviation Conference and Expo in Novi, Michigan. While there, I took advantage of the opportunity to go through the Spatial Disorientation Simulator made available by the FAA’s Civil Aerospace Medical Institute.


It’s a box that contains a single seat with a video screen and flight controls in front of it. You sit in the box in the dark and you fly some basic maneuvers like a climb and some turns. You have a horizon for the first bit of the climb and then you ascend into the clouds.

While you’re concentrating on flying, the box you’re sitting in rotates around its vertical axis something like seven to 12 times per minute. It’ll also pitch forward and back a little.

The simulator lets you experience two vestibular/somatogyral illusions: The coriolis illusion and the illusion that can put you in the so-called graveyard spiral.

The coriolis illusion occurs when you stimulate the semicircular canals by suddenly tilting your head while the aircraft is turning. The simulator rotates slowly for several minutes while you’re flying a simulator. You get used to the rotation and you begin to accept the sensations from your semicircular canals as telling you that you’re flying straight and level. When you move your head forward or back after this, you get the sense that the aircraft is moving in all three axes. I got the sense when I moved my head forward that the aircraft was snapping down and to the right. And the opposite when I moved my head back.

The graveyard spiral happens when you return to level flight after a prolonged bank turn. When you enter the turn, you feel the sensation of a turn in the same direction. If the turn continues for an extended period of time, you lose the turning sensation. Your body has settled into a stabilized mode that’s more or less just like level flight. Then you level the wings. That produces a sensation that the airplane is turning and banking in the opposite direction. If you believe the illusion of the turn (and it’s very compelling), you’ll re-enter the original turn in an attempt to counteract the sensation of the opposite turn.

If you re-enter the turn, you’ll continue in that turn and you’ll start losing altitude. If you pull to get the altitude back or apply power, you’ll only make the turn tighter. If you don’t recognize the illusion and level the wings, you’ll continue the left turn and keep losing altitude until you augur in.


The smooth rotation of the box lets your vestibular system get used to that rotation so that leaning forward and back gives you the coriolis illusion. It can also change rotation to give you that really, really convincing feeling that might lead to a graveyard spiral.

Today’s episode comes in two phases. First, I take the MP3 recorder into the box and fly the simulation. The simulation takes something like nine minutes, most of which is pretty quiet and consists of my flying a climbing turn. I’m going to accelerate the process by fading the audio up and down to tell you where I’ve omitted audio. You’ll hear the simulator giving me vectors and other instructions and, after each of the effects, the initial explanation of the effect that I just felt. You’ll also hear me give a “whoah” at appropriate times. I had intended to give a little more commentary, but I found that the illusions were so compelling that I was processing them myself and couldn’t really talk much about them. I guess that’s what the commentary on the show is for.

At the FAA staff’s suggestion, I exaggerated my head movements to really experience the effect. Note that I didn’t have to move my head much at all to get a really wild sensation in the graveyard spiral demonstration.

So here’s the simulator ride.

[Audio.]

Afterward, I talked to Rogers Shaw, the team leader of the Airman Educational Personnel. Here’s the interview.

[Audio.]

The take-home for this episode is that the things that the textbook tells you about physiological illusions are real. They’re very real. Even though I knew for a fact that I was in a box in an exhibit hall in Novi, Michigan, the sense of opposite rotation was overwhelming. If you’re going to fly on instruments or without a good horizon, you need to know that these illusions can happen and that they can happen to you. I’m glad that I experienced them for the first time in a simulator in Novi and not in an aircraft.

If you have the opportunity, go through this simulation. But even if you don’t, know and understand that your noggin is much more likely than your instruments to lead you astray. Flying in the clouds takes discipline in a number of different respects. Probably the most important is the discipline to get on your gages and believe them, even when everything you’re used to from walking around on the ground is screaming that things are wildly amiss.

Instrument flight is transcendental in many different ways. My personal favorite is breaking out of a cloud layer in a climb and then dragging my wheels in the cloud tops. But the price for that is building the ability to transcend what your senses have told you all your life and to rely on the science and instrumentation in front of you.

Thanks to the FAA’s Civil Aerospace Medical Institute for bringing the simulator to Novi. Make sure to watch for it at a conference or other event near you.

This is a Love Story

Pretty simple entry for the day. Straightforward and true. This is a love story. And it’s not even half way through its first volume.

Great Lakes Aviation Conference 2009


This is a regular blog post. Check out show notes and links to show audio in the other posts.

I spent Friday and Saturday at the Great Lakes Aviation Conference in Novi, Michigan hitting lectures, checking out products, and running into new and old friends on the show floor.

As shown above, I got to meet Jack Lousma, one of the “Original 19” astronauts. The Original 19 was the fifth group, so named tongue-in-cheek because of the size of the class and the perceived lack of novelty of a new astronaut class. The Original 19 would more than prove themselves, not least by preceding many members of Class 4, who were scientists and took additional time to become jet qualified, whereas most, if not all, of the Original 19 were jet qualified from early in their military careers.

Lousma was the pilot for Skylab 3 and commander of STS-3. He has logged more than 7,000 hours of flight time, including 700 hours in general aviation aircraft, 1619 hours in space, 4,500 hours in jet aircraft, and 240 hours in helicopters. And I should mention that he’s as approachable as anyone you’d ever want to meet at your local airport.


There were four aircraft on the floor – The Robinson R44 shown here and fixed-wing aircraft (or mockups thereof) from FlightDesign, Cirrus, and Orion.


Attendance was pretty thin. This is my first time attending. I’ve registered and paid for three years, but was unable to attend the last two years because work dragged me back to the office instead. But it seemed pretty thin both Friday and Saturday. This picture isn’t necessarily indicative – things were a little busier than this, but not a lot more. GA is having its issues all over the country, and I guess I shouldn’t be surprised that it would get the double whammy by being in southeast Michigan.


CAP was there in force, which was great. I got the chance to see Capt Mike Sandstrom, former Swedish Air Force pilot and currently public affairs officer and mission pilot of the Kellogg Senior Squadron.


Particularly nice was getting to see James Schebner of Hillsdale Aero. Hillsdale Aero is a distributor of the FlightDesign CT, pictured above. James was instrumental in answering questions about the CT when there was a real possibility of repositioning a listener’s new aircraft from Ohio to Idaho or Arizona this fall. It would have been an epic series of episodes, but the listener elected not to go through with the purchase. Can’t blame him, given the economy and the outlook at the time.

I’ve decided to head to Hillsdale this summer and get some time in the CT. For a couple of reasons. First, I’ve never flown a light sport aircraft and the CT is a very capable LSA and probably indicative of the high end of the LSA offerings. It would be a great opportunity to report firsthand on LSAs. Second, and maybe more importantly, the fact that all of the newer CTs sport BRS ballistic parachute systems might be the thing that gets Mary to let me fly Cole. Hillsdale Aero’s trainer at the moment doesn’t have a chute, but the company gets new aircraft in from time to time. I’m thinking about getting the required five hours in and then, if Mary green-lights it, taking Cole to Hillsdale when they get a BRS-equipped aircraft on the line.

I talked it over with chief flight instructor Ginger Moore and she seemed to think that that might be a good plan. Besides, visibility in the CT is excellent and it’d let Cole see better during the flight. And, yeah, if we get up, he’s getting stick time. Closely-supervised stick time with me on the controls simultaneously, but stick time nevertheless. Yeah!

Taildragger Training – Part 1

[Audio 01]

We’re going to do a little time travel here. Last April, when I had scheduled the DC-3 type rating course, I figured that it would be a good idea to get some tailwheel training before going down to Griffin. It seemed to stand to reason that it would be a good idea not to have my first tailwheel experience be in an airliner.

I actually needn’t have worried. Other than taxiing (which was an exercise in humility), the ‘three behaved beautifully.

But my tailwheel training has since become a lot of fun and I’ve spent a lot of time in a Citabria since then.


My instructor is Barry Sutton of Sutton aviation at Oakland County International Airport in Waterford, Michigan, although it’s “Pontiac” on the radio. The ICAO designator is PTK, for those following along in their A/FDs.

Barry’s a DE and an amazing instructor. John and Martha King have nothing on Barry for cockpit chatter. Barry is polished and smooth and seems to have a telepathic sense for what you need to know and immediately begins telling you before you have to ask. But Barry also has a talent for being quiet when he senses that you’re working things out, which is a rare thing indeed. I think Barry is the best instructor with whom I’ve ever flown. And I guess that’s saying something these days, as many people who’ve occupied the right seat in airplanes I’ve flown.

Anyway, I got ahold of Barry and scheduled a time to go get an intro to taildraggers and to go do some pattern work.


The airplane today is an American Champion Citabria 7ECA Aurora, tail number N157AC. It’s practically brand new, with its airworthiness certificate issues in December of 2006. It’s powered by a Lycoming O-235-K2C that puts out 118 horsepower at 2,800 PRM and it’ll climb at 740 fpm at sea level. It’s 22 feet long, 34 feet wide, and has 165 sq. ft. of wing area, giving it a wing loading of 10 lb./sq. ft. at its max gross of 1,750 lbs. It’s also certified for basic aerobatics and is rated for +5/-2 gees. I

t seats two in tandem. I’m in front for these flights. It’s a little weird if you haven’t flown a lot in tandem airplanes. You don’t see the instructor directly, so his or her voice is just sort of there in your ears. Like a voice in your head that’s teaching you to fly. Note: If you still hear a voice in your head telling you how to fly when you’re solo, consider a precautionary landing and some rest.

As a note for future episodes, I’ve done a lot of aerobatic training in it and recorded a lot of audio and video that will appear in future episodes.

Flying a taildragger is different in many ways. Probably the most important is that the center of gravity is behind the main gear. If you think about it, that’s an important thing because, if it wasn’t, the airplane would simply rest on its nose with the tailwheel in the air.

The most important consequence is that taking off and landing in a taildragger is a little like pushing rope. If there’s any off-center drag or friction, the center of gravity is going to want to come around from behind you and get in front of you. In a taildragger, that’s called a ground loop and it’s embarrassing at best and can bend you and/or the airplane at worst.

Think of it like this. The nest time you’re in a grocery store parking lot, go grab a shopping cart. Turn it around backwards and put your forearms on the sides of the cart, rest your elbows on the front corners, and grab the sides with your hands. Now run really fast. The cart isn’t very graceful and it gets worse the faster you go. That’s a pretty good proxy for what it’s like the first few times you fly a taildragger.

One other thing as we get started. Barry talks a little about an imaginary nosewheel. He is, of course, addressing the fear by tricycle-gear drivers like me that pushing the nose over will result in a prop strike. The fact of the matter is that there’s a fair amount of downforce on the tail of the airplane and you’d actually be hard-pressed to have a prop strike. Even if you got pretty well beyond level, the prop would tuck under a bit before actually striking the runway.

For all normal operations, you can simply imagine that there’s a nosewheel in front and you don’t even have to imagine very hard. After a certain amount of forward force, the airplane will resist you pretty well and the nose feels pretty stable.

Also, this is my first time flying an aircraft with a stick. You hold the stick in your right hand. Push and the houses get bigger, pull and they get smaller. Left and right are as you’d imagine. The throttle is a knob on the left wall and the carb heat is a smaller knob just below it and you operate those with your left hand. Trim is also on your left, but it’s only marginally helpful for gross adjustments. It’s almost impossible to trim the airplane for hands-off level flight.

The transition from yoke to stick took ten seconds. I’m not kidding. It seemed completely natural immediately. And I love, love, love flying with a stick instead of a yoke. I’d have to get a different kneeboard if I was going to fly the Citabria IFR (and, by the way, it’s IRF certified), but I’d consider doing that. As it is, I fly it without a kneeboard and take notes on my right knee with a fine felt-tip marker. Right on the knee. A prouder tattoo one cannot imagine. In fact, I’ve often considered writing an ATIS on my knee before going out just because I think it looks cool.

The first order of business was to familiarize me with the feel of the rudder at high speed before rotating. To that end, Barry and I did two high-speed taxis down Runway 27L. Barry had the stick and the throttle and got us moving just fast enough to get the tail off the ground. I’m sitting up front with my hands in my lap and feet on the rudders.

Here’s the first high-speed taxi.

[Audio 02]

Not bad. We taxi back and do another one.

Barry and I talk about the first run and get ready for the second one.

[Audio 03]

Then it’s time to do the second high-speed taxi.

[Audio 04]

We taxi back to the approach end of 27L. this time, we’re going to take off. The wind is pretty heavy out of the south and I’m not ready to crosswind operations in this airplane yet. We’re going to ask for a right turn on takeoff and make right traffic around to Runway 17.

You can land a taildragger in two ways. The easier and more common is the three-point landing. As the name implies, you try to touch the mains and the tail all at the same time. A three-point landing is a little easier in the Citabria because the tailwheel is steerable and you have more directional control when the tailwheel is down.

The other kind is a wheel landing. In a wheel landing, you land on the mains and then let the tail fly until it can’t fly anymore. It’s much the same as takeoff except that you’re slowing down. It’s also a lot harder because (a) as a tricycle-gear pilot, you’re overly scared of nosing over and having a prop strike and (b) you don’t have that steerable tailwheel on the ground and you’re instead depending on the rudder for directional control, even though rudder effectiveness is decreasing all the way until the tailwheel makes contact.

All of the landings today will be wheel landings. That’s because the DC-3 almost always does wheel landings. Unlike the Citabria, the ‘three is very stable in a wheel landing. In fact, although the ‘three can and does do three-point landings, it’s discouraged because the tail could begin oscillating up and down and, when a tail that big with that much momentum starts to oscillate, you can have control departures, prop strikes, and other nastiness.

But the Citabria is a good platform for understanding what goes into landings of either kind and we’re going to do some wheel landings today.

Here’s the takeoff from runway 27L and part of the pattern over to Runway 17. You can tell that I’m really enjoying the way this airplane flies.

[Audio 05]

And here’s the approach and the first landing. There’s a lot of convection and other turbulence, so you’ll head Barry coaching me on the throttle until I get the approaches dialed in.

[Audio 06]

Not awful, but I can tell that Barry’s doing a lot of the flying on the landing. We taxi back to the approach end of Runway 17 and I get my second takeoff. I feel pretty good about the takeoff and do most of it myself.

[Audio 07]

We get through the thermals and it’s time to touch down again. I don’t keep the stick forward to keep the tailwheel off and Barry helps me out with that. I’m exhibiting ever reaction that you’d expect from a tricycle-gear pilot flying a taildragger for the first time.

[Audio 08]

We head around the patch again and I put in my worst landing of the day. I keep wanting to pull back when I need to be disciplined enough to keep it forward to keep it on the mains and keep the tail off the ground. This time, we have to play with the power and oscillate a few times before getting the aircraft down and stopped.

I should mention that Pontiac is a pretty big airport with parallel main runways in addition to the crossing runway that we’re on. It’s a rare time when we have the airspace pretty much to ourselves. Barry’s friendly with the guy in the tower and I take the opportunity at the end to try to cloak my landing in a PIREP.

[Audio 09]

We got something like seven takeoffs and landings that day. Here’s the last one. It was a little better than most, but I still didn’t push adequately and we had to play with the power in order to get the right attitude for touchdown.

[Audio 10]

Needless to say, about a month later I had a tailwheel endorsement from Dan Gryder in the DC-3. The ‘three was much easier to fly than the Citabria in many ways. Lots more on the checklist and much more technical to get her over the fence but, once over the fence, docile as could be.

My understanding with Barry is that I’m going to fly the Citabria with him until he tells me that he’d sign me off for a tailwheel endorsement in that aircraft. Then I’ll really feel that I’m a tailwheel driver. Most of the flights since then have been aerobatic for the first hour and then pattern work after that. As I record this in mid-January, I haven’t been up in the Citabria since November, but I’ll be back in the saddle as soon as I can get there.

I think the Citabria is my favorite training aircraft thus far. It’s yellow, it’s new, it’s clean, it has great visibility (including a transparent roof), you sit on the centerline, you have your feet up on the rudders, you have a four-point harness, and it’s a genuine stick-and-rudder pilotmaker. Captain Chris of Plane madness did an informal poll on Twitter a few months ago, asking, if money was no object, what two aircraft would you own. I responded with the F-86 Sabre and either a Citabria or the Citabria’s big brother, the Super Decathlon. It’s that much fun.

Stay tuned because there’s lots more tailwheel and aerobatic audio stored up from the last year. And I’ve shot a lot of cockpit video of the aerobatic stuff, so I’m planning to release some more video episodes, too.
