Agree with that Beagle. I hope it will be to AOPA or someone similar in the UK, and not just a copy of the FAA question bank which may not translate so well.
The current exams issued October 2014 are greatly improved in that they give answers which point to references in the Air Pilot Manual and also the AFE series by Jeremy Pratt, with edition numbers and page numbers, which is absolutely essential in a debrief.
There are also reference to occasional other books.
To do a proper debrief I assume that a GR would have access to a master answers book so that candidates can be shown where to look.
What would make sense is if the textbooks to reference was standardised on one publisher.
The Air Pliot Manuals were originally the "Trevor Thom" series. It was originally written for the Australian PPL and CPL, - and it shows. Masses of irrelevant materiel; the only useful UK specific book was Air Law and Met.
It would be best if all references were to the AFE series only.
We already have 3 x 120 questions, which is 360, so 600 is not took much of a stretch.
Outsourcing to some EASA approved outfit in Europe must be resisted at all costs ! English speakers only writing exams please.
