Yes Capt. Vilo, AFT a great school, and has a great reputation.
However, there is a relatively new school called Flightpass at Exeter. These guys have started IR since getting their brand new FNPT II at the end of last year. Heard / read good reports about them for their FI(A) Courses. A friend of mine was there last year doing his FI(A) and he couldn't be more complimentary. Very experienced ex. RAF / Cathay and G/A instructors apparently.
If you cannot get a booking with AFT, as they do book up quickly, try Flightpass. Good luck.
