cacnhaaduaeinr Qer OPERATING MANUAL PSP 601A-6 SECTION 3 AURAL/VISUAL WARNING SYSTEMS GENERAL There are two aircraft central warning systems: the aural warning system, which provides audible tones associated with eight significant events, and the master caution and warning system which advises the crew of system malfunctions. AURAL WARNING SYSTEM (Figures 1 and 2) The aural warning system monitors several events and provides a separate aural warning for each event, as follows: Event Engine fire Overspeed Airspeed too high for flap setting Stall Incorrect take-off configuration Altitude alert Landing gear not down and locked HF call detected by selcal unit Autopilot disconnect (Aircraft 5041 and 5146) Warning Fire bell CI acker Wailer Warbler Intermittent horn C chord Horn Chime Cavalry charge The aural warnings are presented on the flight compartment speakers and the intercom system. The take-off configuration warning circuitry monitors the throttle setting, landing gear and control surface positions to ensure that they are correct for take-off. If they are not correct and the throttles are advanced towards take-off power, the take-off configuration warning circuitry provides an output to the aural warning system to sound the intermittent horn. The aural warning system consists of the aural warning unit and test panel. On aircraft 5041 and 5146, Liit! aural warniny sysiem consists of two aural warning units and a test panel, SECTION 3 Page 1 Aug 14/02 cacnhaadnaeinr per OPERATING MANUAL PSP 601A-6 3. MASTER CAUTION AND WARNING SYSTEM (Figures 3 through 6) The master caution and warning system is an indicating system that provides the flight crew with aircraft system caution, warning, advisory and safe indication annunciations. Cautions are annunciated by amber lights, warnings are annunciated by red lights and advisories and safe indications are annunciated by white or green lights, depending on the function of the light. The annunciator lights are not part of the master caution and warning system, but are part of the systems that the lights concern. The related systems are shown in Figure 3. Legends on the 10-channel and 8-channel annunciator panels also come on (amber) to identify the malfunctioning system. Two master caution lights, located on the glareshield, flash (white) to indicate an active caution annunciation on the 10-channel or 8-channel annunciator panel. Warning, advisory and safe indication annunciations do not trigger the master caution lights or the legends on the 10-channel or 8-channel annunciator panels.
