There is no secrecy in AOPA working group activities. Everything we do is open to discussion and review.
I think you are confusing the regulator working groups that AOPA members volunteer to sit on. These are are government, regulator etc and there are rules applied to them that we have to agree to. This often means that we are not permitted to disseminate directly the content of the meetings. As with all working groups doing things over a period of time things change, views change etc, and so often it is better to get to the end of the process and 'keep your powder dry' before making announcements of the process.
Generally speaking we try to speak publicly where possible about the goings on but where restricted there is nothing we can do. As a citizen I am sure you could make appropriate requests under the FIA or whatever the Europe equivalent is for the EASA meetings but really at the end of the process it all comes out into the public domain anyway.
So please understand there is no veil of secrecy around any of the AOPA activities.
