Legendary pilot Bob Hoover demonstrates pouring iced tea while executing a barrel roll in an aircraft. I remember doing some zero-G maneuvers while getting my pilot’s license. Very fun and unusual feeling. I can’t imagine the precision required to do this type of flying. Well, I can, actually, because learning to fly requires learning very precise movements and developing a feel for the airplane unlike what you develop in a car. It’s more akin to the feeling you develop learning to ride a bicycle, or even a unicycle. What amazes me is the fact that Bob is able to fly a consistent one-G barrel roll while he’s pouring the tea backhand. Now that’s coordination.
One of my favorite things I did in flight training was learning to cross-control the airplane. If you think about it, an airplane’s flight surfaces (ailerons, rudder, elevator) do their normal jobs with respect not only to the forces of lift, but in relation to the force of gravity. Once the airplane gets past a certain point with respect to gravity (past 45 degrees, that is), the flight surfaces start to behave in weird ways. For example, in normal flight, pulling back on the yoke will cause the elevator on the tail to move up, thereby causing the nose of the plane to rise and the aircraft to gain altitude. So pulling back means going higher. But what if the plane is twisted over on its side? Then pulling back means that the airplane goes into a tight turn with respect to the horizon. This is the origin of the so-called “death spiral” that has caught out many pilots when they’re in limited visibility conditions. It’s one of the reasons that you need special training to fly IFR (Instrument Flight Rules-in the clouds, basically).
VFR (visual flight rules) training gives all pilots a little bit of exposure to this type of flying. Enough to be able to recognize problems and extricate ourselves from them. Anyway, back to cross-control. Part of training involves getting the airplane into all sorts of weird orientations and then trying to fly a consistent path. I really liked flying the airplane at slow speeds and torqued over on its side. At that point, you have to use the flight surfaces in a very non-intuitive way- the rudder becomes the elevator and the elevator becomes the rudder. Once you get the feel for it it’s like trying to drive a right-seat car with the stick-shift on the left, with your feet, backwards, while looking through the rearview mirror. Very challenging and fun. Since there’s nothing to hit up there, and since you always do this at altitudes you can recover from in the event of a mistake, it’s a fun exercise.
I want to go flying now.
