Perhaps time for all these organisations to talk to one another???
We can only wish.
The point I was seeking to make is some issues one can understand may be specific to individual organiations, however there are an increasing number of issues were it would seem there should be a great deal of common ground.
A "select committee" brings together the considerable expertise from all these organsiations (for example whilst the PPL/IR may be small group, they have some technically very able individuals) and perhaps more importantly I bet that committee could rightly claim to represent more than a majoirty of UK pilots.
As it is AOPA has around 4,500 members out of a UK pilot populaton reported to be 54,000 - less than 10%.
