Cpt KC,
Your plan looks very much like the course OFT offer?
Phase 1
FAA Private Pilots
JAA ATPL Ground School - 24 Weeks
Phase 2
FAA Instrument Rating
Phase 3
Structured Hours Building
Phase 4
JAA Multi Commercial
Ground Instructor Time (50 Hrs)
So I wouldn't say you're doing anything new? But I can see the benefit and have thought of this route myself.
I did think of doing:
PPL with EFT/OFT
fly home
ATPL exams with BGS while in full time work and earning
fly back out there
FAA IR with OFT
JAA Multi-CPL with OFT
fly home
Convert my FAA IR to a JAA Multi-IR with Cabair (or in Spain - Aerodynamics).
Apply for the sponsored Instructor route at Cabair and work there for a year or two.
I could still do the above but I'm trying to look at as many different routes as possible. (looks like Cabair has pulled the plug on the sponsored FI but there are alternatives I'm sure).
