[NSRCA-discussion] Fwd: AOPA Aviation Summit: Think you know spins?

[Murray Johnson]

It works on all Pitts models. Just like in the video clip if there is an
overcontrol applying anti-spin inputs a secondary opposite spin will
develope. That is, if a positive spin is overcontrolled a negative spin will
occur. Vice versa for a negative spin. The Mueller-Beggs recovery
is designed to bypass this condition by instructing you to let go of the
stick. An overcontrol is impossible with this recovery technique. Problems
occur when a pilot thinks he is in a positive spin when in fact it may be
negative as they look almost identical from a cockpit POV, especially if the
spin ensued from a botched maneuver. Thinking he is applying anti-spin
control inputs my be exascerbating the spin mode. Panic finishes the
excercise. In full scale acro it is absolutely essential to get spin
training if you want to live to a ripe old age. Luckily when we do this with
a model 99.999% of the time we just walk away with a little lighter wallet.
One of the reasons why I switched!!

Have a look at the clip of the "Beast" accident. He was a very, very
experienced pilot and see how the secondary spin occurs in the attempted
recovery.
