Everything in the NPA is pointing to option 2: establishing the BTO concept. So I guess that is what we should expect?
"The only real quibble I have with NPA 2015-20 is that it hasn't considered inclusion of training for the 'Basic IR' (being developed by the RMT.0677 Task Force) within the scope of a BTO."
Exactly my thought, BEagle. Consultation time is now and until Feb 29th. I hope you are going to write EASA about that - I am definitely going to. Basic IR is part of the "easier access to instrument rating for GA pilots" Task Force in EASA, and what could be more "proportionate" than to allow the Basic Training Organisations to train for that too.
