Mat, training yourself to use an AOA indicator takes about 30 seconds - it's
really obvious. Training to use the ASI for pitch attitude without
reference to the visible horizon takes many hours of intensive training and
even then most pilots don't do it well.

Surely most pilots - after their first few flights - are capable of
hitting and maintaining a desired speed as shown on the ASI?

AOA indicators are about reducing information overload, not increasing it.
An AOA indicator IS a stall warning with far greater resolution. The EASY
way to fly is with an AOA. The HARD way is to do without it.

So why don't we all have them?
