The last brief for UK Examiners was:
6. FLIGHT EXAMINER (PPL) STANDARDISATION SEMINAR
We have been notified of a one day Seminar for PPL(A) Flight Examiners to be held at Cranfield on the 28th October 2004. Although this is not a CAA requirement, it looks like a good opportunity for standardisation, to refresh Examiner techniques or to discuss changes to flight-testing procedures and it is intended that a CAA FE will be in attendance.
And that was run by ETA, a private company!
