AURAL WARNING TEST
Most aural alerts are exercised as part of their own system test. For all other aural
alerts, an AURAL WARNING TEST can be initiated via the Electrical Management
System Control Display Unit (EMS CDU) located on the pilot’s and copilot’s side
panel. There are two warning test selections provided to test the Integrated Avionics
Computer (IAC 1 and IAC 2).
NOTE
TEST is initiated by pressing activation key and can be
terminated by pressing activation key again.
The test sequences through each tone and/or voice message in the following priority
order:
• AURAL WARNING TEST 1 aural or AURAL WARNING TEST 2
• STALL (stall shaker active)
• Continuous tone (overspeed)
• Triple Chime tone (any warning)
• NO TAKEOFF
• LEFT ENGINE FIRE
• RIGHT ENGINE FIRE
• APU FIRE
• SMOKE
• CABIN ALTITUDE
• GEAR BAY OVERHEAT
• LEFT REVERSER UNLOCKED
• RIGHT REVERSER UNLOCKED
• NORMAL BRAKE FAIL
• Single Chime (any caution)

AURAL WARNING PANEL
The aural warning panel, located on the overhead panel, is used to disable the tone/
aural generators located in IAC 1 and IAC 2. Aurals for EGPWS and TCAS will not
be inhibited by muting the IACs.
INHIBITS
During takeoff and landing, the IAC fault warning computer will process inhibit logic
to minimize spurious or distracting messages. Warnings and status messages are not
inhibited except for CABIN ALT and APU OVERTEMP (T/O only), NORMAL
BRAKE FAIL, BRAKE OVHT, CABIN DELTA-P.
During takeoff, the caution and advisory messages are inhibited when:
• Weight On Wheels; and
• Indicated airspeed transitions from less than 80 knots to greater than or equal to 80
knots
The caution and advisory messages inhibit is removed:
• 25 seconds after Weight Off Wheels; or
• Pressure Altitude is greater than or equal to takeoff altitude +400 feet; or
• Indicated airspeed is less than 50 knots; or
