No idea what to put as a title
I think spin recovery is a very good idea. Being able to recognise the difference between a spiral dive and a spin is a matter of life and death. The wrong correction could be devastating. I believe CAEOAA has made spin recovery mandatory. This might be an EASA rule but it's late and my memory is.... Ummm....
The issue is that unless the airlines keep up the training what OAA does will be pointless because you will probably be in a spin 20 years after you did the 4 hours in training.
