Thing
I think we are basically on the same page. With respect to gliders my contention that care must be taken with comparison to powered aircraft is meant as a generalization. If Derek Piggott was flying a C 172 and the engine failed I expect we would find the undamaged aircraft neatly parked in front of the local with him inside enjoying a pie and fresh pint
My contention in all of the threads I have posted on the engine failure issue is that, in general, unwarranted attention is given to the engine failure scenario in GA, IMO to the detriment of the things that are actually much more likely to cause an aircraft to be wrecked.
Yes I believe an engine failure is an emergency. However like any other emergency we should reduce its probability by proactive management of the factors that could cause the engine to fail and reduce the severity of the outcome if the engine were to fail by attaining and maintaining good flying skills.
