And with a newly acquired aerobatic rating ( 5 hours total) + a handful of extra hours (FCL.800) an FI will be able to teach
The same goes with mountain flying
It takes decades of experience in these niche activities to reach proficiency, the right guys for this are very often not ATPL or CPL holders nor FI's...
And the CRI ???
anyone with 300hrs TT SEP and a a valid rating ( 5hrs training !!) + a couple of extra hours, including some ground courses, without the FI can apply, and we may have some very qualified people together with a whole bunch of hopeless chaps who will have acquired their credentials not because of their skills but due to their connections and some connivent FI(E).
