Grade 3's are able to provide instruction up to the CPL.
Yes they can, but they won't be delivering CPL training. Not in any school I know of. If an airline pilot is migrating back to CPL Instruction, there's a fair bit to get back on top of.
The basic restrictions are:
- Can't send first solo's
- Can't perform flight reviews
- Can't grant RPL navigation endorsements
With all due respect, you're calling those 'basic' restrictions?
You're talking about what they theoretically can do, I'm talking the reality of this scenario. I think that's what this fella is looking for.
The reputable schools that are forking out for the training approvals require return of service or bonds, personally I don't think these candidates will hang around for that long.
