Needle, ball..............airspeed got a lot of pilots out of trouble by hand flying the aircraft to a stable condition.
I think that most pilots will not disagree with this and it would probably have prevented some serious accidents in the past !
Being a glider and power pilot (tail dragger, no less !) gives me a basis for being critical of using 100% auto systems. One must be prepared to take over manually at any time and keep flying on an even keel and sort things out ! Therefore, manual flying should be encouraged across the air transportation spectrum.
