The 'committee' is not elected. Any member may volunteer and sit on any of the working groups if they have relevant skills to offer. The membership of the working groups is fluid as members commitments change.
I rather thought AOPA was a limited company, limited by guarantee since it has no shareholders and no shareholding.
I also thought its constituition was determined by its Memorandumn and Articles of Association which determines how directors may be appointed and replaced.
I wonder how many of its members know how this process works?
Why is this relevant?
In order to make a decision whether you are happy with the representation you are receiving you should base your decision on the facts.
If you and other shareholders dont like what your directors are doing and if the company is controlled by its shareholders you can sack the lot of them, if you dont like what your club is doing you can stand for election to the governing committee once a year.
