Barry, there is no huge urgency to rush into a decision on your papers. There are other far more important matters which the NPPL P&SC must agree on first - such as the formal ANO amendment which needs to be drafted correctly this time.
Both the GAPAN instuctor committee and AOPA's instructor committee now have copies of your papers and will study them before their next meetings, all of which are totally voluntary and unpaid. It would be a bit much to expect them to hold extraordinary meetings to discuss something for which there really isn't any huge urgency.
You've already tried to drum up support on this thread for NPPL-holders to be permitted to instruct for the NPPL. That didn't receive any overwhelming response for or against, so it needs time and detailed study. Even if a vote in favour was forthcoming, the law of the land requires that a regulatory impact assessment must be held - and you've got little chance of that being achieved quickly.
Use of permit aeroplanes for flight instruction? Some have fairly 'individual' handling characteristics and are perhaps unsuitable for training ab-initio pilots. Who would approve individual types for training? I would vote for the CAA, not the PFA. As I've said before, restrictions which currently apply to permit aeroplanes (such as not being permitted to fly over congested areas at ANY height) preclude the teaching of cetain exercises - how are you going to navigate PROPERLY if you have to keep turning off track to avoid overflight of any built-up area. Perhaps it would be better just to press for an easing of the current maintenance and inspection requirements for training aeroplanes?
Use of other than licensed or government aerodromes for certain training activities is already being looked at by the CAA; let's hear what they have to say first and then perhaps negotiate.
But general approval for NPPL-holding FIs to instruct in permit aeroplanes from any aerodrome? I doubt it; although some might be fine, the floodgates could open to dodgy operators with tatty old cloth bombers working out of muddy farm fields. That sort of thing must be resisted at all costs.
AOPA consults with industry and they started the whole NPPL ball rolling. GAPAN assists and observes, BGA, BMAA, GAMTA also consult with their industry members and speak for them on the NPPL P&SC. Let the industry bodies study your proposals and discuss them in committee when they've had a chance to do so.
One thing that most people do agree upon, however, is that there should be no relaxation on medical standards for FIs below the JAA Class 2 medical which is all a JAR-FCL PPL hodling FI(A) currently needs for non-remunerated flight instruction.
