Farrell,
I am thinking of doing the CFI / CFII / MEI. I have been looking round a few places and think I have settled on one but its a case of getting about 4-5 weeks off work to go and do them.
Hi CZ,
I did the high performance at the FBO I was using at the time. Its an instructor signoff.
The High altitude I did at Proflight in Carlsbad, San Diego as had a few days left after I completed my checkride. The endorsement allow you to operate high altitude pressurized aircraft under 61.31(g).
