Any flight instructor will opine that the fourth time you get unceremoniously dumped out of a departure stall in one day of training, the serene attitude of instrument flight starts to look pretty good. No negative Gs, no spins just good, aerodynamically solid flight at gentle attitudes. But the world is changing. The purpose is to prepare pilots for a divergence from normal flight due to turbulence, either wake or natural. While there is a Boeing for almost every conceivable chore, they haven t built an aerobatic version yet.
Aerobatic specialists provide the training in special aircraft.
The message is that airplanes do function inverted, and if there is sufficient altitude a very important detail an upset should not be a death sentence. Few private pilots ever see an aircraft upside down or in a spin. At the typical FBO, the training machines are not well-suited or may be prohibited from performing these maneuvers. The garden-variety CFI frequently has limited training in spins. Both pilot and aircraft must be up to a more demanding task than normal flight.
