I chose the FTO (Aeros @ gloucester) because I felt that I was paying for quality training with people who cared about the standard I achieved.
For the purpose of PPL Training you will find that Aeros is a Registered Facility. The FTO covers the professional training that they do and uses different instructors. So what you are really saying is that all RFs are not the same, but then neither are FTOs!
All JAA PPL training conducted in the USA is at an approved FTO where the standard may be well below the standard at many RFs!
