ALPA sent this out. They have a FastRead System which is basically a blast email chain for things like this. You will probably added to that list shortly I am sure.
You may have spoken to John Taylor, who in fact is the National Aeromedical Chair and a XJT Pilot. There was a big conference call today with the ALPA Pilot Assistance Committee (I am the Vice Chair of the Pilot Assistance Committee) which encompasses the Aeromedical Committee (with four other Committees), a ton of staff members in the know, and the ALPA Aeromedical Service. John Taylor couldn't make the call, but there are a lot of moving pieces with this and false information out there so don't fault him if he said something different yesterday as there are conflicting aspects of what the FAA has and hasn't put out. John does fantastic work.
Today, we were briefed on exactly what is going on with this proposed policy and then the above FastRead was sent out.
