Tinstaafl,
I agree entirely. But that is my point. Just logging the demo part is not what I am suggesting either.
The bloke on my first post this thread was technically not even doing his 3 take offs/landings every 90 days...
I believe if you are going to log time to watch someone else fly then perhaps a logbook regime similar to the co-pilot system might be more appropriate.
Do not get me wrong - Instructors are a vital part of the aviation community, sometimes undervalued (in more ways than one) in my opinion. Requiring a high degree of skill.
Steering is the easy part. Although we might have trouble selling that to say the crew at Gimli, for example.
