Public Address System

The Federal Aviation Administration proposes to amend an airworthiness standard for the public address system on transport category airplanes. The proposal would shorten from 10 seconds to 3 seconds, the time allowed for the system to become active after a flight crewmember removes the microphone from its stowage. A time requirement is imposed to assure the system is rapidly usable for emergency announcements. Adopting this proposal would eliminate regulatory differences between the airworthiness standards of the U.S. and the Joint Aviation Requirements of Europe, without affecting current industry design practices.
