foxmouth, yes, ASI is all you need I would've thought but even looking at the vid that I posted, it's difficult to understand how you can see the ASI from the rear
And yes, that's a good idea. Maybe on one of the flights I will fly it from the back seat with an instructor just to make sure I can do it well. I was only thinking of doing it in case I decide to take somone up in the future.
I have 1 more little question:
I was told by someone that the Basic AOPA Aerobatic Course (6 hours of aerobatic instruction) can now be converted to a rating in EASA.
Is it a requirement to have the rating instead of an endorsement? Can you choose which one you want to have (sorry I know that sounds a bit stupid) and if you must have the rating, then when does it expire?
Thanks
