And in flight failure of the magenta line will kill commercial pilots never mind ppl's and its something the industry is looking to solve.
What with a back up dual ipad's ?
Back to the spinning and avoiding it and if in it recovering, surely the pilot had to do many wrong things to get in that position, fly to slow (and not recognise it) stall the wing (and not recognise it and recover) so the chances if this is inadvertent of recovery is in my opinion very low.
A spin is an Aerobatic exercise that I personally believe has little value in time and money well spent for flying high performance GA aircraft. (Although I would like to do it some time for the experience only)
Stall and Spin accidents in GA are very often fatal and often at circuit altitude where recovery technique and the chute are useless so avoidance training is the key
