I did my ME IR training at BFC last year, leading to a first time pass and could not rate them higher.
The standard of instruction was first rate, from each of the 4 or 5 instructors I ended up flying with in the sim or A/C.
Regarding pass rates, I don't know how they rate against the average but believe 1st time and 1st series passes are good. If you give them a call, sure they will oblige in telling you. The figures for the past six months were always posted on the notice board when I was there.
Very proffessional outfit, and if you're a good boy/girl you might even get a RHS ride in the King Air!
