I visited them when I was looking at doing my flight training. They seem like a fairly large operation, well equipped office / briefing areas and well set up FNPTII that mirrors a BE76. Not sure how many core full time instructors they have and had some difficulty getting precise information on student / instructor ratio.
What did surprise me at the time was that for a physically large looking operation, they didn't have many aircraft - think it was three BE76 plus 2 SEP. I wanted to do my IR first, then my CPL and when I pitched this to them (for good reasons as I already had +1000hrs TT and an ICAO CPL/IR) the answer came back "why on earth would you want to do that?" This was a bit of a clincher for me as I was concerned on their flexibiity to tailor training.
So I walked across the road and visited Professional Air Training. The rest is history. Clearly I'm now a fan of PAT and have no regrets.
