View Full Version : My first taste of aerobatics.

So for my first "live"* biannual flight review I figured I wouldn't just have my CFI go around the patch with me for three reasons:

1) Being in a familiar aircraft at a familiar airfield and over familiar territory might not point out my weaknesses like they should. I didn't want it to be a check-the-box-requirement-is-fulfilled drill.

2) My CFI is great, but he's so used to the way I fly that he may not notice any bad habits I've picked up - or, more remotely, I may have picked up one of his bad habits.

3) Might as well learn something new while I'm at it.

So I called up Greg Koontz, aerobatic pilot extraordinaire, and in a pink of hubris scheduled some upset training in a cheerful, confident voice. A bit like Pee Wee Herman getting a lesson on how to ride his bicycle from Lance Armstrong.

He's a very approachable, friendly, and professional guy. I half expected him to tell a Sport Pilot with less than 60 total hours that it would probably be better if I waited until I had more hours and better skills before I waste his time, but he gave me a half second pause and then smiled at me.

Weather went from marginal to acceptable (I had done all the requisite things to ensure this - hope the neighbor doesn't ask too many questions about why I was out in the backyard at midnight wearing a robe chanting and where the heck did his cat disappear to?), with a rising overcast that was to break up around the time we were to actually fly. I knew I should have picked the red cat over his calico as the timing was a bit off, but that was okay.

We covered the fundamentals of flight from the perspective of aerobatics, and he was pleasantly surprised that I had a good grasp of what makes airplanes do what they do. I left it up to him on what I'd learn, and he said to keep it simple and give a good idea on what aerobatics is that we'd do just one maneuver - aileron rolls.

Soon we were out to the decathalon (same one as in the video), I was strapped in with a parachute and given instruction on the aircraft.

First time in an aircraft with prop pitch control. Manifold pressure? Wazzat? And look at all the stuff on the dash - at least the compass looks friendly. Hell, one has to work fuel mixture on this aircraft. In the Champ it's just there for decoration. Loads of power, too.

So out we taxi onto his grass strip - first time for that, too. Very different from pavement; grass is slippery stuff, and bouncy, too. But I managed to keep us straight and up we went at 80 mph once I learned to pitch up a bit more in the champ and come down from 120. Zoom, that plane is fast!

There was a nice hole in the clouds, so we climbed up through it and over the top of the overcast. First time flying over clouds like that. Pretty and no thermals, but uncomfortable. And since he wanted me to climb on heading at a set speed. He had me do some stalls; it was to familiarize me with the aircraft, but also to check my skills (it's a biannual, too, remember!). I unplugged my internal navigation thinking. We did some stalls and some steep turns (after he growled about my "747" gentle turns - guilty!), and then it was time to roll.

An aileron roll is really a zero-G parabola with a lot of left or right stick to rotate the axis of fuselage around itself. No rudder or elevator is given in the maneuver, as the idea is that the aircraft should keep doing what it's doing, only with the wings rotating around. Simple enough - one pitches up, pitches forward until zero G is felt, brings the stick to neutral and then hard left or right. When the roll is completing, return the stick to neutral and then level out from the zero G flight path.

Okay, not so simple. My first attempt had me using some odd inputs (zero G is NOT a normal sensation), and we put both negative and positive G (-1 and +2) on the meter. Hmmm, don't rush it, he says calmly afterwards. During the maneuver itself he was speaking in tongues, at least briefly.

Let's do another. Hey, I did it! Very cool. It's a timing thing, but one has to feel for it. Climb and turn to a set altitude (Mr. Koontz is a real pro, and a bit slick - more flight review skill stuff without announcing it). Do three more to the left and then two to the right.

By now my stomach was beginning to show signs of disquiet, and being totally without shame I told him we were done with that unless he wanted to turn it into nausea training to the point of failure. He genuinely chuckled and said he appreciated me being honest about it - some people think it's a sign of weakness to admit to motion sickness.

In fact I was whipped.

We found a large hole in the overcast in the direction of his airstrip and he was happy I could descend at a set rate on a set heading - I guess I had muffed some of the other stuff!

Time to do some landings. We set up for a left pattern to his strip, and I did a very sloppy pattern and bounced the landing. Swishied the roll, too, and took off for another. A little better on the next, but waay too close in on base to final - go around. Man, I'm looking like an idiot and those close in Champ patterns aren't doing me any favors in this hotrod. Big slip and I salvage it with a nice three pointer.

"Not the kind of precision with throttle and pitch I'd like to see," he noted, we'll talk about your slips and slides later." Oh, man, I suck!

But I was struggling and didn't know why. I do touch and goes almost exclusively. Okay, head check. First, fly the darned pattern like it's a pattern and not your personal patch. Second, grass strips don't have lines or numbers or stuff on them. Gotta pick a spot more overtly in my mind to land on. And third, get that pattern bigger; this plane is a lot faster.

Up and around for a right pattern. There we go - nice three pointer with a nice straight track on roll out. Turn around and put her in the barn.

And then the critique. Hmmm, I tend to slide on the turn from crosswind to downwind, and when I slip tend to move stick before rudder instead of using both at the same time. Recommendations?

1) Fly more. Need more experience. I still have fewer hours than a lot of Private Pilot students. Working on that - gotta get the plane finished so I can afford to build up hours.

2) Do pattern work at other airports. It's obvious that I've gotten so used to flying the pattern at my home airfield that I'm doing it mechanically and almost out of habit. I came up with that idea and Mr. Koontz looked pleasantly surprised that something like that would come out of my thick head.

3) Keep working on basics, aiming for precision.

4) I ain't all tore up as a pilot; nothing got broke (not even our feelings) and we got to fly in an airplane. No real bad habits and he says my attitude is correct about aviation.

And I'm not ready for real aerobatics yet. My skill set just isn't where it needs to be for that kind of precision flying.

* My first biannual was actually accomplished a year after I got my license through the WINGS program. I took some online courses through the FAA and did the flight instructor portion when I got my tailwheel endorsement. It's a grand idea, but really doesn't measure up against an hour of ground instruction and an hour in the air with a CFI with the intent of evaluating skills.

Frank- nice write up, but I think you should look at it the other way around. Consider continuing aerobatic training as a way to push your flying skills rather than thinking you need to develop some arbitrary level of "additional skill" before continuing. No need for that. Aerobatics is its own thing and there are no prerequisites other than very basic flying ability and understanding of basic flight dynamics. The student pilot and the 5,000 hour Cessna pilot are on the same level when it comes to learning acro. WWII-era pilots learned basic aerobatics in the Stearman during primary training. Keep it up!

Regarding precision aerobatics, that takes lots practice no matter how good a "stick" you are when starting out. Learn to gain competence and a comfort level with all the basic maneuvers, and the precision will come through lots of practice. You can make aerobatics as easy or as difficult as you want. Most recreational aerobatic pilots don't put much effort into real precision flying. At the end of the day, you're only an unsuccessful aerobatic pilot if you're unsafe and not having fun. It really doesn't take a lot training to simply become safe performing the basic maneuvers. In-depth spin training is very important here, and goes hand-in-hand with basic aerobatic training.

I will add that if you do not already have a Commercial Pilot Certificate, after a couple more hours of acro instruction, you will find the Commercial Flight Test maneuvers very very easy.

IAC Chapter 27 hosts the annual Armed Forces Memorial Aerobatic Contest over at Grenada, MS at the end of May. http://iac27.org/new/ Life is always more fun when you can rub elbows with folks who share your interest.

Best of luck,

Hi Frank,

Great to hear you got a little acro. I've done a little and plan to do a little more (basic stuff) now that I have my Citabria out of the "annual from heck". Since mine only has 100hp, it isn't quite like the Decathlon you flew in. But is is faster than a Champ (a little)

I know the feeling when it's time to quit. I went in a Great Lakes and the front wind screen is very low. Well at 6-2, my head stuck out with the slipstream hidding me square in the forehead. No helmet, just sunglasses. After 30 minutes and 3 or 4 rolls, all that wind had my brain scrambled. (more than normal). I'm going back for more though.:rollseyes:

Go after it again. It'll grow on you.

Thanks for the kind words, all!

Well I've got to get that darned plane finished so I can fly regularly without breaking the bank renting the Champ.

Then I can start thinking of breaking the bank getting aerobatic instruction! ;)

One thing, though, is that I found landing on grass more difficult than landing on pavement, which seems to be contrary to popular convention. Grass is so slippery that one has to work harder to keep the track - at least for me. I like the grip of pavement - when it goes bad it can go very bad quickly, but it seems like corrections are more responsive. Then again it may be the difference from the very tame Champ to the high performance Decathalon.

It might seem like I'm being harsh on myself in the write-up (I'm actually a pretty okay pilot), but I went into the biannual looking for things to improve, and asked Mr. Koontz to be unvarnished in his appraisal of my weaknesses.

And I can't stress enough what a class act and all around great guy Mr. Koontz is. He could have charged double his rate and it still be a value (but don't tell him that - I want to bother him again in the future!).

Frank awesome write up - I'm already looking ahead to my first Bi-annual Flight Review next year and this might be worth the trip. I had the privilege to get upside down in a Waco this past week and it was eye-opening to say the least!

Here's a video of some "gentlemen's aerobatics" -- simple rolls -- I took yesterday off the Texas gulf coast. The aircraft is our Van's RV-8A.

Enjoyed best on a big HDTV:

I made a mount for the GoPro that screws on using two of the wing tip attachment screws. It can be mounted on the top or bottom of the wing, facing any direction.

Here's one from last night's flight, shot from inside the plane.

Nice video. Mary really holds a nice line in the rolls.

Are you using the Go Pro 3? I have a GP 2 and mounts but haven't used it yet.

Dale

Yep, the 3.

Amazingly, the mount I made is derived from the black plastic platform that the camera comes mounted on in the box. I was somewhat concerned that it would be strong enough, but it's survived a dozen flights. :D

I drilled/countersunk appropriately sized/spaced holes, and trimmed off the corners with a band saw to minimize any lifting tendency. It works pretty well!

Here's a pic:

Frank, Congratulations. I think you are going to have a long period as a good pilot and one who enjoys aviation.
There are a lot of people who don't want to hear any suggestion of how they might do something better and certainly not anything that they might be doing wrong. So they don't change anything, they don't grow. When it comes to biennial time, they often take the easy way out, or the cheapest way.
My own Brother was a little bit like that, he was a very careful and expert instrument pilot, and flew a twin Bonanza and a Queen Air. When it came time for the flight review, I told him I knew someone who had a B-25 and would give him the instruction and time in it, for a reasonable fee, but he wasn't interested at all. He did it in a C-150, just whatever was cheap and quick. He was a championship golfer, and took a million lessons, but to him an airplane was just a way to get to a business destination, or football game, or hunting trip. The flying was incidental.

You reached out for your biennial and tried to make yourself better in your training. I did a similar thing years ago, I got some acro instruction from an old master, Duane Cole near Ft. Worth. I recall coming in for landing and not being able to see over his shoulder to see the instruments on the panel, so I asked him if the ball was in the center. He told me a turn coordinator was just a gimmick that was invented to sell to more people and that I should just trust my seat of the pants feeling for coordination. He flew at a different level than most of the rest of us. His inverted gliding descent, engine out in his Taylorcraft is still one of my favorite act. Best of all, his flying did the talking, rather than many of these new guys who have to have an announcer screaming at the crowd to tell them how great the pilot is.

I'm with Eric, you don't need to wait. In fact, I think some acro training will ultimately make you a better pilot.
You'll learn what all the flight controls really do. Hopefully...the hook is set!

Congrats on your flight!

I too decided that the BFR was the perfect chance to explore things I hadn't done in an airplane. I did one as a 100 hr. PP in an Extra 300L and it was the best hour I've ever had in an airplane! My instructor for the flight was a co-worker who used to fly unlimited and airshows in the Extra, so he could make that plane do just about anything. I mostly wanted to get the basics of rolls, loops, and spins both ways, but at the end of the flight, since I wasn't sick yet, I had him do part of his old airshow routine with me following him along, what an absolute blast. Also got to find out that 6.5 g's is the point at which I lose consciousness. Even as a low time pilot, with no high performance time, I learned more in that hour than most of my previous flight training put together. I'd highly recommend an intro to acro as a way of really fleshing out your flying skills, even for a low time pilot.

6.5 Gs...ugh. I've done 4.5, and that was enough.

With my aerobatics instructor, we never went over 3 Gs, and after 30 minutes I was beat. At 3Gs I weighed 600 pounds, so it was like a half hour of weight lifting, combined with adrenaline and stress.

Great fun! :D

It is important to start aerobatics with shorter flights. A lot of folks find that G's take some getting used to. The traditional 1 hour training flight often does not work for acro. Shorter, but more frequent flights are better at the start of your acro skill building. When I started I never thought that I would type that my average hop involves +6 and -3 G. But today it does. That said, my G tolerance goes down over the winter when I fly less and in the spring I have to start slow and build up. In the spring I leave the first inverted spins of the season to be the last figure of a hop.

Yeager said that he learned to fly with a bucket between his knees. I take that to mean that anyone can do it if they want to enough. And sport flying is about personal challenge.

Oh, it is harder to be a passenger through acro as your body is generally a step behind what the airplane is doing. When you are the one flying you instinctively brace in anticipation and start straining against the G's ahead of them. And one important aspect of G's is knowing how to resist them by straining. I will suggest that if your pilot or teacher omitted that from your preflight brief, that individual omitted an important topic. No one should go to sleep during an acro demo.

Best of luck,

Wes

At first, rolls left me dizzy and disoriented. Now, I do them on every flight, just for fun -- so I can definitely see how aerobatics becomes easier and more tolerable over time.

In all fairness to my instructor, who I know quite well as a co-worker, he tailored the flight to what I was feeling up for that day. I planned for just an intro to unusual attitudes, rolls and spins was my main goals to experience for the flight. After 20 minutes of that, and feeling good, he added in hammerheads and cuban 8's. His procedure is to demo a maneuver, then do one with the student following on the controls, then student attempt with him backing up to prevent big oops type stuff. After that I requested to just do some windup turns because I wanted to see firsthand what my untrained tolerance was. After that, and still having some time, I told him to just do some of his old unlimited routine because I was curious if was as violent as it looked from the ground. That consisted of a series of point rolls with lots of reversals, snap rolls, and a shoulder roll/lomcevak. I had a blast the whole time, but understand it wouldn't be for everyone. His more normal intro is much tamer and is again tailored to what the student wants and can tolerate, and he's done so many rides he has a good feel for how much is enough, even before the student knows he or she is done.

If you're ever in the Los Angeles area, he operates out of MHV, name is Chuck Coleman. http://www.ctcoleman.com/v2/ He and I were co-workers at Scaled Composites, although we've both since left. He used the Extra to fly the low chase on SpaceShipOne, so some really neat experience.

Gday from Western Australia,I would like to concur with all that has been said about aerobatics during training.Back in the 70s I was learning to fly and while I was sort of getting it I was not smooth and accurate,which gave me the snake pits.The guy that owned the flying school was a Pitts driver and suggested some aeros in his decathlon.After A couple hours of stalls,loops,spins,stall turns I got it and it all fell into place for me though I never got the snap roll real good.So yes aeroobatics are a great way of improving eye hand and feet coordination. Cheers Ross
