Illuminated

An amber light (related to the illuminated system

annunciator), has illuminated on the forward

overhead panel, aft overhead panel, oroverheat/fire protection panel.

To extinguish the system annunciator light(s),

push either MASTER CAUTION light.

To recall the system annunciator light(s), push

and release either system annunciator panel.

This action will re-illuminate the MASTER

CAUTION lights and the related system

annunciator(s) if the fault condition still exists.

Note: The system annunciator panels are also

known as recall panels.

System Annunciator Panels:

A single fault in certain redundant systems do not

illuminate the MASTER CAUTION or associated

system annunciator light. These faults, however,

are stored in the master caution system. Pushingeither system annunciator panel recalls the single

fault, which results in the illumination of the

MASTER CAUTION and associated system

annunciator light. To reset the system, simply

push either MASTER CAUTION light.

Examples of single faults are: MACH TRIM FAIL,

SPEED TRIM FAIL, AUTOSLAT FAIL, and one

LOW PRESSURE light illuminated in a main fuel

tank. Please see the Flight Controls presentation

or Fuel presentation for additional information.

Fire Warning System

FIRE WARN lights:

Illuminated

Indicates a fire warning in the engine(s), main

gear wheel well, or APU. Lights remain

illuminated as long as the fire condition exists or

until the crew resets the fire warning system.

A fire system test is being performed.

Fire warning bell sounds.

Remote APU fire warning horn sounds during an

APU fire if the aircraft is on the ground.

Push

Extinguishes both FIRE WARN lights.

Silences fire warning bell. Silences remote APU fire warning horn (ground only).

Resets fire warning system for additional fire

warnings.

Note: Pushing the BELL CUTOUT switch on the

overheat/fire protection panel results in the same

four items listed above.

MACH AIRSPEED WARNING TEST Switches:

Push

Tests the No. 1 or No. 2 Mach/airspeed warning

system.

Clacker sounds

Two independent Mach/airspeed warning systems

provide a distinct aural warning (clacker) any time

the maximum operating airspeed of Vmo/Mmo is

exceeded. The clacker may only be silenced by

reducing airspeed below Vmo/Mmo.

Listen to the clacker




Stall Warning




Stall Warning

STALL WARNING TEST Switches:

Push

Tests the No. 1 or No. 2 stall management

computer by shaking each control column.

No. 1 stall management computer shakesCaptains control column. No. 2 stall

management computer shakes First Officers

control column.

Either stick shaker vibrates both columns

through column interconnects.

Test vibrations are inhibited while airborne.

Test can only be done while on the ground with

AC power on the aircraft.

The stall warning stick shaker consists of two

eccentric weight motors, one one each control

column. They are designed to warn the pilots

before a stall develops. The system is armed in

flight at all times.

Listen to the

stick shaker

Landing Gear Configuration Warning

Control Stand


14/16

PT. METRO BATAVIA



A steady warning horn is provided to alert the

pilots whenever the aircraft is in a landing gear

configuration and any gear is not down and

locked. The warning system monitors the

position of the landing gear, forward thrust levers,

and trailing edge flaps to determine if the horn

requires activation. Depending on the position of

the aforementioned items, the HORN CUTOUT

switch may or may not silence the warning horn.

The warning horn may also be silenced by simply

correcting the configuration error; e.g. extending

the landing gear.

HORN CUTOUT Switch:

Push (trailing edge flaps 1 through 10 units)

Will silence the warning horn if either or both

forward thrust levers are between idle and

approximately 10 of thrust lever angle.

Push (trailing edge flaps at 15 units)

Will silence the warning horn if either forward

thrust lever is between idle and approximately

10 of thrust lever angle and the opposite

forward thrust lever is greater than

approximately 30 of thrust lever angle.

Will NOT silence the warning horn if bothforward thrust levers are below approximately

30 of thrust lever angle.

Push (trailing edge flaps greater than 15 units)

The warning horn cannot be silenced regardless

of forward thrust lever position.

Takeoff Configuration Warning

Listen to the takeoff

configurationwarning horn

The takeoff configuration warning system is armed when the aircraft is on the ground and either or

both forward thrust levers are advanced for takeoff. When advancing the forward thrust levers for

takeoff, an intermittent warning horn will sound if any of the following five conditions are not met:

1) Trailing edge flaps must be in the takeoff position (1, 2, 5, 10, or 15).

2) Leading edge Krueger flaps must be in the takeoff position (fully extended).

3) The SPEED BRAKE handle must be in the DOWN position.4) Stabilizer trim must be within the stabilizer trim green band range.

5) Parking brake must not be set.

The takeoff configuration warning horn is cancelled when the configuration error is corrected.

Note: The sound of the takeoff configuration warning horn is the same sound as the cabin altitude

warning horn.
