Once I got
the Instrument Rating, I was faced with the question, "What next?"
I'd like to get a Commercial Certificate and cement the achievement
by actually earning money flying an airplane. If I could get someone
to actually *pay* me, say, $100 to do something, anything, then that
would set me indisputably apart from the amateurs. And getting Commercial
requires that you learn to fly well. In fact, it requires that you fly
very, very well. It's a Professional Pilot's standard. But achieving it is a long process and I was looking for something shorter term. I mentioned this to Charlie, the proprietor of Wings Pilot Shop at the Nashua, NH airport where I buy many of my toys, and he suggested aerobatics.
"There's
a school right over there," he pointed, "It's called Aerial
Advantage and Rob Holland is one of the best in the country." Spins kill a lot of pilots. The training used to be part of becoming a Private Pilot but so many students and instructors died practicing them that the requirement was eventually dropped. On my way through Private I had asked my instructor for a demonstration. He obliged, and even let me try one or two myself, but the bewildering speed with which the low wing and nose headed for the ground, and the frightening snap as the high wing came around made me more fearful than ever.
Eventually I contacted Rob, explained the situation, and asked if spins were one of those things that became less mysterious with practice. I had read of many pilots who started out fearful of spins, and all the accounts said that pilots who practice them enough, actually come to enjoy them.
The military
insists that student pilots become proficient in spins before they can
even solo.
Rob said
yes, it was possible to learn enough about spins through practice that
they became just another maneuver - something to be respected, but not
feared. He explained that Aerial Advantage offered a five lesson course
which would lead to a "Spin Endorsement", a formal statement
by an instructor that the named pilot had received training and demonstrated
proficiency in performing spins. Certified Flight Instructors, among
others, must have such an endorsement. He also noted that practicing
spins in an airplane rated for aerobatics was much safer than doing
so in a Cessna, where spins are only begrudgingly permitted. Finally,
he mentioned that AA offered a ten lesson course in Basic Aerobatics,
which included the spin training and a tailwheel endorsement. Completing
the course would mean I could rent the Decathalon, practice aerobatics
on my own, and maybe even enter a local competition, flying against
other beginners like myself. Flying solo
aerobatics was so far beyond my expectations as to be meaningless, but
the tailwheel instruction rang a little bell. My very first flying experience
was in 1960 when Grandpa Hollis took Cousin David and me out to Weiss
field and treated us each a 30 minute lesson in a Piper Cub. I've still
got the logbook, which is now half filled in, and here was a chance
to attain some closure on the initial gift. So there
it was. I could learn to fly a taildragger, experience a "Victory
Roll", and maybe even a loop, and do so with an accomplished professional.
The chance was simply too good to pass up. I paid for the ten lesson
course. Meeting Rob
Holland turned out to be a lucky chance. He's a young guy, early 30's,
who started out on the Airline Pilot track. After becoming one, he found
himself getting bored hauling passengers back and forth and decided
to specialize in aerobatics instead. He and some investors formed Aerial
Advantage, acquired the Pitts and the Decathalon, and hung our their
shingle. Rob teaches, performs at airshows all over the country, and
enters aerobatic competitions to measure himself against other pilots.
He had just returned from Europe where he had placed 10th overall, and
first among U.S. pilots at the FIA Worlds. The course
was laid out in a syllabus, and backed up by a textbook. I was expected
to arrive for each lesson with the background reading completed, prepared
to explain those materials which I understood and ask questions about
those which I did not. Every day there would be a ground school discussion,
followed by a flight of about an hour.
The ground
school for the first lesson was over two hours long. It was all about
Safety. Rob explained over and over, in every way possible, that I was
not there to become a Waldo Pepper daredevil. I was not going to learn
to fly with a leather jacket and long silk scarf that would impress
the ladies. I was not going to do things that nobody else thought could
be done. I was going to learn to fly the outer reaches of the performance
envelope and I was going to do it SAFELY. There was
a long list of AA House Rules and we went over each one, word by word.
No aerobatics at night. Strict VFR [Visual Flight Rules] weather. No
aerobatics other than in the carefully prescribed Practice Area. "Hard
Deck" at 4,000 feet. It went on and on. When we were done, I had
to sign the list indicating that I agreed to the conditions. Then we moved out to the airplane and spent another half hour discussing Emergency Procedures. How to ensure that the parachute was legal and had been repacked in the last 120 days. How to put it on. How to know when the straps are tight enough (Hint: If you can stand up straight, they aren't). How to make a
parachute
landing in a field. How to land in the trees. How to land in the water. We walked
around the airplane doing the most extensive and exacting pre-flight
inspection I had ever heard of. Check every bolt for tightness and every
hinge for freedom of movement. Tug on the exhaust pipe to test the engine
mounts. Tug on the propeller blade tips to check the hub bearings. Look
under the seats for loose gear that might fly around the cabin when
we turn upside down. Drain fuel from each of four access points to check
for water or contamination. Check the brake lines for leaks. Tap the
fabric under the aft fuselage and listen for any forgotten item bouncing
around. Check each and every slotted bolt for a properly installed safety
wire or cotter key. Look at the Recording G Meter to see how much stress
occured on the last flight. Then back into the hangar to empty our pockets.
Nothing is allowed in the airplane that isn't securely fastened to something
else. Finally,
Rob helped me get belted in. There are seven straps. One over each shoulder,
one up from the floor between the legs, two lower belts for the lap.
These five get joined in a single fastening, and are then individually
hand tightened. Over all these go the two upper belts for the lap, which
are hand tightened, and then further tightened with a winch. The lap
belts hold you to the seat. If they are very tight, they hold you to
the seat well enough that you can fly the airplane inverted without
swinging around like a pendulum or worrying that you're going to fall
through the overhead window. I learned that they have to be very tight
indeed.
Eventually,
we started the engine and taxied out. This was my introduction to flying
a taildragger. They are much trickier to handle on or near the ground
than the more modern tricycle gear airplanes. The difference is the
location of the Center of Gravity relative to the main wheels. In a
trike, the C.G. is forward of the mains. This makes the airplane stable
to taxi and easy to land. Taildraggers have the C.G. aft of the mains,
which makes them dynamically unstable when taxiing, and downright treacherous
when landing, particularly in a cross-wind. Here was a whole new world
of things I might learn to do well. Once we took
off, I discovered yet another unsuspected learning opportunity: I really
didn't know how to fly an airplane. All I had flown to date were Cessna's
and Piper Cherokee's, airplanes used for primary training which are
so stable that they practically fly themselves. They are designed this
way. They are popular because they are so easy to fly. The Decathalon
trades off some of this stability for controllability. If you want a
high roll rate, you can't have an airplane that wants to keep its wings
level. If you want an airplane that will fly upside down, you have to
give up some of the stability that makes it want to fly right side up. In short,
the Decathalon does what you tell it to do, not what you want it to
do. And in my 250 hours of flying I had never experienced an airplane
that actually had to be TOLD what to do. All the others could figure
it out for themselves. This one didn't. I slipped and skidded and yawed
all over the sky. I was simply terrible. We continued
with some stalls. First a power-off stall with the usual recovery, losing
less than a hundred feet of altitude. Then a power-on stall, and recover
without losing any altitude at all. This was a standard of proficiency
I had never imagined. I couldn't do any of it. Fortunately,
Rob is an excellent instructor. He has the knowledge and knows how to
communicate. He also has the experience to know that students start
low and grow high, so he does not react with impatience. And he has
that rare, delicate knack of offering encouragement and support, while
also letting the student know that there is so much more that can be
accomplished. I would curse my clumsiness into the headset microphone
and he would calmly reply, "You're doing fine. You're going to
get it. I can see the progress already." Then we did
something else I never imagined: A power-off stall with a delayed recovery.
All primary flight instruction includes training on stalls. Stalls are
an essential part of landing, which is nothing more than a controlled
stall just above the runway surface, but can be dangerous if they happen
anytime you're not landing. And because of the latter contingency, the
emphasis is on recovering from a stall as quickly as possible. The idea
of letting the airplane continue in a stalled condition is never mentioned,
and I therefore concluded that if you *didn't* recover immediately,
the airplane would go completely out of control. It turns
out, they don't. Rob talked me through it. "When it breaks, just
keep the stick back. The wing won't be flying so don't bother with the
ailerons. They won't work. Instead, use the rudder to keep the wings
level." I entered the stall and the nose dropped. We sank and sank.
The left wing dropped but standing on the right rudder brought it begrudgingly
back up. It worked! Here was a corner of the flight envelope that I
didn't even know existed. Finally Rob said, "OK, stick forward,
unstall the wing and pull out of the dive." Finally,
we did an aileron roll. This is a ballistic maneuver, flown in a shallow
arc that requires very little from the airplane. Nose down to gain speed;
pull level; pull the nose up about 30 degrees, give it full left aileron
with left rudder to match, and hang on for a full rotation. Properly
done, the airplane will make a graceful 360 degree roll and end upright
in a shallow dive. My first attempt wasn't so graceful. The second was
somewhat better, but nowhere near good. We
called it a day and returned to the airport. I got out of the airplane
drenched with sweat. I had done something I never expected to do, and
learned about four or five things I didn't know existed. It seemed to
me the whole course had already been worth the money.
The
second lesson built on the material from the first. Review the safety
stuff. Get in. Fly to the practice area. Do a couple aileron rolls to
the left. Do a couple to the right. Improvement was noticeable, even
to me. Then
we did a slow roll. This is not done in a ballistic arc, it is a straight
line maneuver which means that the control timing and coordination is
much more critical. Begin the roll with left aileron and left rudder.
As the wings approach vertical, shift to hard right rudder to keep the
nose from dropping. As the wings go past vertical towards inverted,
ease the right rudder somewhat and push the stick forward to keep the
nose from dropping. As the wings go past inverted, pull the stick back
and shift to hard left rudder. As the wings come level, ease off the
left rudder. It's actually more difficult than it sounds.
Lesson
Three was loops. By now I was doing aileron rolls for a warmup exercise.
By Lesson Five I was no longer skidding and yawing all over the sky,
and was warming up with slow rolls and loops. By Lesson Nine, I was
warming up with Reverse Cuban Eights.
Lesson
Ten was the Checkride, a review of everything and anything we covered
in the course. Before we boarded, Rob told me that I was doing the first
half of the lesson entirely on my own. I was to start the engine, taxi,
take off, fly out to the practice area, clear the area for traffic,
and do a loop. During all this he would observe my performance but would
say nothing. I got through it OK. We
practiced a simulated engine-out emergency landing, and then headed
back to the airport.

As I write this, Page 16, November 16, 2004, begins with a single entry:

Hammerhead Turn
|
| The Hammerhead
Turn is a wingover carried to an extreme. Start out straight and level with a good head of steam, then pull sharply up into a vertical climb. When the airspeed has bled off to almost nothing, kick hard left rudder to 'pivot' (read: yaw) the airplane 180 degrees around its (and your) vertical axis (which is currently horizontal). This leaves you pointed straight down, more or less along the path you followed on the way up and when you pull out of the dive your heading is exactly opposite that of the entry. It's kinda like running across a floor, up the wall, then spinning around to run down the wall and back across the floor. (Evan) |
