AMC1 CAT.IDE.A.175 Crew member interphone system ED Decision 2014/015/R SPECIFICATIONS The crew member interphone system should: (a) operate independently of the public address system except for handsets, headsets, microphones, selector switches and signalling devices; (b) in the case of aeroplanes where at least one cabin crew member is required, be readily accessible for use at required cabin crew member stations close to each separate or pair of floor level emergency exits; (c) in the case of aeroplanes where at least one cabin crew member is required, have an alerting system incorporating aural or visual signals for use by flight and cabin crew; (d) have a means for the recipient of a call to determine whether it is a normal call or an emergency call that uses one or a combination of the following: (1) lights of different colours; (2) codes defined by the operator (e.g. different number of rings for normal and emergency calls); or (3) any other indicating signal specified in the operations manual; (e) provide two-way communication between: (1) the flight crew compartment and each passenger compartment, in the case of aeroplanes where at least one cabin crew member is required; (2) the flight crew compartment and each galley located other than on a passenger deck level, in the case of aeroplanes where at least one cabin crew member is required; (3) the flight crew compartment and each remote crew compartment and crew member station that is not on the passenger deck and is not accessible from a passenger compartment; and (4) ground personnel and at least two flight crew members. This interphone system for use by the ground personnel should be, where practicable, so located that the personnel using the system may avoid detection from within the aeroplane; and (f) be readily accessible for use from each required flight crew station in the flight crew compartment.
