The FAA late this afternoon responded to AOPA safety and operational concerns over the implementation of the ADIZ surrounding Washington by issuing notam 7/0206. The revised notam addresses safety concerns posed by pilots by allowing frequency changes to the common traffic advisory frequency (CTAF) to "self-announce" intentions when operating in the traffic pattern. The revised language states that pilots conducting traffic-pattern operations will be exempt from the ATC communication requirement provided they monitor the airport CTAF. However, pilots will still be required to file and activate a flight plan and be required to "squawk" a discrete transponder beacon code. "This notam addresses a critical safety concern of pilots," reported Heidi Williams, manager of air traffic. "We immediately responded by working with the FAA to have the notam language revised."
