The new owner of Aeros is Tom Dunn, who also owns Pilot Flight Training at Wellesbourne.
He is a very successful business man, albeit with only limited experience in the flight training business, but given he has a 5-year plan in place to acquire a total of 25 (yes, I did say 25) flight schools in the UK, you can be fairly sure that Aeros will not disappear overnight with your money.
That said, nothing is certain in the aviation training business, and in the current recession-threatened climate unless you are intending to undertake integrated training at Cabair, Oxford or FTE, then pay as you learn, not up front. If Aeros can't make it through these troubled times without having your money up front, then the writing is on the wall not just for them but for all UK commercial FTOs.
As far as the standard of training is concerned, then this is the last place you should be asking such questions. Visit the school, talk to the instructors, and more importantly, talk to the students.
