As an examiner I have not had one piece of comms from the CAA about this, I heard through one of the schools I am affiliated and also through the email notification I have signed up to for Licensing, Engineering, ATC, Medical, Standards etc. Anyone can do that but surely the CAA had a duty to inform directly the people this procedure affected.
Anyway, perhaps we should take the lead from the UK airlines - I believe the airlines have been lumbered with many awkward choking procedures that could see many pilots/instructors/examiners becoming grounded with no valid qualification. They have got their heads together and taken it to the CAA. Words to the effect of - if this ain't fixed you shall shortly have few airlines left to manage and claim you revenue from.
Perhaps we should all do the same - OR, just sit back and watch the fallout around us. I can see this whole business going a##e over t#t sooner rather than later - with any luck.
Shame on the CAA.
