In a memo from TSA this morning, CHQ pilots will be instructed that they are allowed only in the footprint of the aircraft - and in the ramp space from the aircraft to their assigned gate. ATL Airport Security is concerned that too many CHQ pilots (without ATL SIDA badges) have been found wandering the D ramp. The concern is that it is a Security Breech for them to be on the ramp or in other non approved areas. ASA personnel have been directed to remind any wayward CHQ pilots to exit the ASA Crew Room areas or report the violation to the phone numbers posted in the crewroom.
