Exactly what I think you should do, vancouv
Clubs insist on the check, instructor goes along for the ride but then wants to log the time as well - not really "training" per se...
Maybe they could charge for the groundschool if they have to teach FPL filling or some-such, but X-channel checks I wouldn't have thought come under the remit of "training for the grant or renewal of a licence or rating"
When you go to a new club/school and they want a check flight before letting you rent the aircraft how is that check flight logged? (Assuming you weren't doing any diff. training)
I suspect some schools/instructors will expect to claim the time for themselves as P1, but that ain't right shirley?
