OPERATING MANUAL
SECTION 3
AURAL/VISUAL WARNING SYSTEMS
GENERAL
There are two aircraft central warning systems, the aural warning system, which
provides audible tones associated with seven 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 seven 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
horn
Altitude alert
Landing gear not down and locked
TONE TEST SWITCH
FIRE
OVSPD
FLAP OVSPD
STALL
TOC
AURAL WARNING
Fire Bell
CI acker
Wailer
Warbler
Intermittent
ALT-ADV
LDG GR
C chord
Horn
The system consists of two main components, an aural warning unit and an aural
warning test panel• The aural warning unit has seven tone generators.
Depending on the event, one of the tone generators is triggered. The output is
fed via amplifiers to the pilot1s and copilot's headphones and to the flight
compartment speaker system.
The aural warning test panel has a TONE TEST switch, a PRESS TO MUTE switch
and a VOLUME CONTROL. Setting the TONE TEST switch to the selected position
triggers the associated tone generator. When the TONE TEST switch is set to
the FIRE or FLAP OVSPD positions, the tone can be muted by pressing the PRESS
TO MUTE switch which also causes the TONE MUTED light to come on. When the
TONE TEST switch is set to the STALL, TOC, ALT-ADV, LDG GR or OVSPD positions,
the tone cannot be muted by pressing the PRESS TO MUTE switch and the TONE
MUTED light does not come on. The aural warning system can be tested by
selecting each event, in turn, on the TONE TEST switch. The VOLUME CONTROL
adjusts the audio output level.

OPERATING MANUAL
MASTER CAUTION AND WARNING SYSTEM (Figures 3, 4, 5, 6 and 7)
The master caution and warning lights provide a visual indication to the pilot
and copilot of an aircraft system malfunction. Safe indication and advisory
lights provide a visual status indication of aircraft systems. A specific
fault is indicated by an individual system warning or caution light and, for a
caution light, also by a system legend on the 10-channel or 8-channel system
annunciator panel and by two flashing master caution lights mounted on the
glareshield.
Warning lights (red) that may require immediate action by the flight crew are
not annunciated and do not trigger the master caution light flasher.
Caution lights (amber) that may require future action by the flight crew are
divided into two groups, annunciated and not annunciated.
Safe indication and advisory lights (white or green) are not annunciated and
the colour of the light varies with the light function.
When either MASTER CAUTION PRESS TO RESET switch/light is pressed, a reset
signal is sent to the 10-channel and 8-channel system annunciator panels and
the annunciated legend and master caution lights go out, thus arming the system
to display a subsequent fault. The individual system light remains on and only
goes out when the fault is cleared.
If the TEST-RECALL switch is set to RECALL after reset and the affected system
annunciator legend comes on again and both master caution lights flash a fault
