Michigan Aerobatic Open 2012 – Day -3


A down day to get some work done for clients, do laundry, and snag a little sleep, and it’s back to it.

On Sunday, I left the Battle Creek airshow shortly after finishing my narration gig for the Tuskegee Airmen glider demo team.  I picked up Don Weaver in Jackson and drove him to Ray and loaded up a care package for the Pitts.  Don then flew the Pitts to Jackson and I headed home, where such laundry, work, and other more mundane activities ensued.

Fast forward to this morning, when I awoke at the Pi Pi Pi House (which is what we’ve dubbed this dorm at Spring Arbor University where many of us are staying).  Off to Jackson County Reynolds Field, where the Pitts awaited.

I signed on to my second FAA waiver.  As you’ll recall, the waiver is necessary to cover things like aerobatic maneuvering, fuel requirements, altitudes, and other matters.  It essentially allows us to do stuff in Class D airspace that not even a retiring Lt Col on a fini flight would consider.

I realized that I couldn’t find my acro shoes.  They’re actually just wrestling shoes and there isn’t anything special about them other than the fact that they’re narrower than my usual tennies and are less likely to snag when I move my feet up or down on the rudder pedals to use the brakes.  I can feel the pedals a little better and wrap my toes around the turface features of the pedals, too, so that’s a plus.  I had to hit Dunham’s to buy another pair, but was rewarded with a pair that fits even better than my old pair.

The flying was reasonably good.  A couple of half-hour flights.  The idea is to get my tummy settled down.  As many of you know, I don’t really have the stomach for acro.  I’m the dog who continues to chase cars even though I have little business doing so.

The first flight was all positive G with little or no roll.  I can pull G all day long.  It’s roll that messes with my head.  So we flew loops and half Cubans for awhile.  I’d been having issues with getting all wing-low on the float in the loop maneuvers anyway, mostly because I’m pulling the stick back and to the right.  I’m now pulling straight back and that’s really helping.  It’s always easier when you’re not trying to correct in the float when you see the horizon appear and start creeping down the glass all cock-eyed.

On the second flight, it was all about the reverse half Cubans.  (Pull up to a 45, roll inverted, stick it there for a few potatoes, then pull over the last 5/8 of a loop.  I had never flown a reverse half Cuban before, but managed to pull them off.  The issue was figuring out what the float is supposed to look like and how long to hold it.  I also needed a sight picture.  I tried looking left to the sight gage, but, if you’re a guy who doesn’t like roll, you should not be rapidly turning your head left and back while inverted.  It turns out that, if you can find a cloud as a reference, that’s best.  If you can’t, you can try to use the horizon low and outside as a gage, assuming that your roll to inverted was true.

Toward the end of that flight, I had Don demonstrate a humpty-bump (the fifth maneuver in the 2012 sportsman).  That’s a pull to the vertical with a half loop at the top.  Very short upline (unlike the hammer) because you need the energy to get you up into the float for the half loop.  We got a little slow up there, but made it over.  I’m going to pull after only three potatoes or so in the upline.

Tomorrow, we hit the hammerhead hard.  That’s the newest maneuver and the one I’m most concerned about getting right.  If I can nail the hammer and the spin, I think that everything else will fall into place.  (We’ll see how that process works out for me . . .)

Off to bed.  Three flights to get in tomorrow!

 

Front Seat, Back Seat: Pitts Acro and Transition

There’s front seat and back seat. And they mean different things in different aircraft.

In the Pitts S-2 models, the front seat is pretty bare-bones. You have a stick, a throttle handle, and a prop control. On the panel is an altimeter, an airspeed indicator, a manifold pressure gage, a tachometer, and a G meter. And nothing else. Not even a whiskey compass.

And you can’t see much of anything, either. The front seat is up close to the upper and lower wings. You can see forward over the nose through the cobains (the struts that mount the upper wing to the fuselage, not the dead rock star). You can see a little bit around the wings. You can see from side to side when a wing isn’t blocking your view. And the sight gage is about 20 degrees behind you instead of directly at your nine-o’clock.

But here, in the front seat, is where you begin to fly the Pitts. This is where you learn the rudiments of flying this powerful acro monster.



The back seat is better in all but a few respects. You can see much better because you’re further away from the wings. The sight gage is directly to your left. It’s really striking after you’ve been in the front.

But, with the back seat comes a lot more workload, You start and shut down the airplane (and hot-starting a Pitts is MUCH more art than science). The mixture and trim controls are back there. You have to watch the temperatures and pressures. You have to tune the radios and watch the GPS.

It makes sense to start out in the front. For one thing, as long as you have a talented and trusty IP in the back, you can pretty much just climb in and go, thus making lessons a lot more efficient. You learn to be very technical and precise with your airspeed and other elements of landings because you don’t have a lot of outside stimulus to tempt you to just wing it. And, if you’re not very precise with your feet just yet, you have a very short arm from the center of yaw and you aren’t going to make yourself sick on the early flights by failing to be coordinated (although your instructor will likely suffer kidney damage if you’re really wild).

You have to get pretty good at landing the Pitts from the first seat before you move to the back. Landing a Pitts from the front is one of the hardest things I’ve ever done. You line up on the runway and set airspeed for precisely 95 KIAS. At about 50 AGL, you make one last check for deer on the runway and begin the flare. You lose all visibility in front of you. You just wait for the runway edges to sneak into your peripheral vision and then hope that you sink in a landing attitude until meeting the runway a little above stall speed.

If you don’t see both runway edges after a few seconds, it’s time to go around. It’s not hard to land left or right and I can easily imagine taking out an entire row of runway identifier lights.

If you get it down, then it’s full back on the stick to keep the tail down and you tap dance down the centerline while sneaking your feet up onto the brakes to think about slowing it down.

This is what you need to do reliably before you move to the back seat.

Once you get to move to the back seat, you have a new learning curve to deal with, but that happens fairly quickly. And then you can get on with the business of flying acro with better visibility and situational awareness.

There are any number of reasons for starting out in the front seat, but I buy the one that has to do with the instructor. Landing a Pitts from the front seat is very hard. But I would imagine that recovering somebody else’s bad landing (or other botched maneuver) is even harder in the front seat. Thus, when you go to the back seat, your IP is necessarily moving to the front seat. It would be a really good idea if you had made most or all of your major screw-ups in the front seat (while the IP can have an easier time recovering from the back) before moving to the back seat and putting your IP up front where things are not only harder, but where your IP isn’t likely to be called upon urgently until you’ve already served him or her a crap sandwich from which you’ll be expecting him or her to help you escape.

The shots in this post were taken during my last practice session at Ray before going to Jackson for the IAC Michigan Aerobatic Open. I’ve since done the first flight of my back seat transition and I’ll get some stills and video of the transition flights soon.

In the meantime, the Pitts just gets cooler. I can feel a genuine addition coming on!
