If you do a search on this site, this topic seems to come up pretty regularly and, having posted at length on this in the past, I am going to simply re-paste what I put before.
"I learnt with Airways Flying Club (or BAFC as it was then known) in 2003/4 and, having visited various schools on nearby fields and taken trial lessons with at least two others (including one national chain that seems to feature lots of hour building teenaged boys in white shirts and gold braid) and came to the conclusion that BAFC were the best outfit around, by some degree.
The fleet of Warriors is immaculately kept by the in-house engineering department (I can't remember any of the fleet going 'tech' during my course) and the instructors are either career instructors or semi-retired airline pilots trying to give something back to GA.
Dick Thurbin was the instructor taught me, and his common-sense, relaxed style got me through the course very effectively indeed. I'm sure the other instructors are great, but I took the decision early on in my course to try to stick with one individual - for the sake of consistency.
At Booker, there is a full tower, rather than information or radio - so the r/t is more of a challenge; this is great preparation for the future as, if you can cope here, you'll cope anywhere!
My advice to anyone about to embark on a PPL is to do the rounds of the various schools and have a good look around before committing yourself to one school - take a trial lesson at the final three you're considering, as this will be money well spent in the long run.
I like White Waltham very much (I'm a member down there and enjoy the bar and club atmosphere a great deal) but reckon, as a school, BAFC are still the 'gold standard'. "
PM me if you want further advice or info.
(BY THE WAY, I'M NOT ASSOCIATED WITH AFC OR ON COMMISSION...!)
