Ironicially, BGS is used by integrated training providers - CTC for example
Actually, BGS is not used by "integrated training providers", if by that you mean providers of the JAA Integrated ATPL course. By definition, those training providers must include the necessary ground training in their own course.
CTC run approved modular courses for the JAA CPL(A) and IR(A) as well as a MPA type rating. These courses are combined with and follow PPL(A) training and hour building in New Zealand - for a NZ licence.
The fact that the CTC marketing blurb refers to this as 'integrated' (note the lower case 'i') is a source of some annoyance to Cabair, WMU, OAT and FTE (ex BAe), which are the only UK approved providers of the JAA Integrated ATPL(A) course. But then, when could you ever trust a school's marketing department?
This is in no way intended to suggest that BGS ground training or the CTC course is in any way flawed - in fact, it's probably the best course around and certainly the only one to include a MPA type rating.
