Speaking as a former student of theirs, Tayflite are a bit of a mixed bag. Some of the staff were brilliant, others did indeed have a rather condescending attitude (one female instructor in particular). Few of us there felt like schoolkids rather than customers. They are very busy, and subsequently run a pretty tight schedule in terms of pushing you along, or fitting you in should you need to train around work. That approach also creates problems when people are encountering difficulties with parts of the course. Got a sense that they were a bit irritated to have folk hanging around too long, or coming back for another crack at the IR.
That said, they've put a lot of people through the IR. Would go elsewhere for the CPL though. Better to head across the apron to Tayside for that one I reckon.
