How is an ENG OVERHEAT condition indicated

MASTER CAUTION, OVHT/DET annunciator & associated ENG OVERHEAT lights illuminate

3

What does an illuminated fire control panel FAULT light indicate when no fire test is being performed

Both loops on one engine have failed in the dual loop position (NORMAL) or selected single loop on an engine has failed

4

The FAULT light illuminates on the engine fire control panel with no fire test being performed. Are there any other lights or indications

No. No additional indications are triggered with a FAULT light on

5

What are the power sources for engine fire detection & extinguishing

Detection- Battery bus; extinguishing- Hot Battery bus

6

Which statement regarding the engine fire extinguisher bottles is correct

Two bottles available for either engine

7

How is the squib on an engine fire extinguisher bottle armed

Pulling the fire switch arms the squibs

8

How are the engine fire warning switches ( red handles) released

Released by overheat, fire or manually

9

How is an engine fire extinguisher bottle discharged

Pull illuminated fire warning switch up, rotate either to the left or right

10

What does an illuminated BOTTLE DISCHARGED light indicate

Extinguisher bottle has discharged

11

What is the function of the OVHT/FIRE position of the FIRE TEST switch(Normal AC power on the generator buses)

Tests all aircraft fire and overheat loops

12

During an extinguisher system test (squib test) what does an engine fire extinguisher illuminated green EXT TEST light indicate

Discharge circuit test is normal for respective extinguisher circuit

13

Which statement describes the APU fire detection system

Single loop system for fire or fault detection

14

What does an illuminated APU DET INOP light indicate when no fire warning test is being performed

Failure in the APU fire detector loop

15

What occurs when an APU fire condition is detected(cockpit only)

APU fire warning & master FIRE warning lights illuminate and fire bell sounds in cockpit and APU shuts down

16

What are the initial indications of a fire at the APU Ground Control Panel (On The Ground)

Flashing Fire Warning light and intermittent horn

17

In the event of an APU fire warning, what occurs when a cockpit FIRE warning bell cut-out switch or the APU Ground Control Panel (GCP) HORN CUTOUT button is pressed

Cockpit fire bell and GCP horn are silenced, GCZp light illuminates steady

18

How is the APU extinguisher bottle discharged from APU Ground Control Panel

Pull fire control handle, then activate discharge switch

19

Which describes the WHEEL WELL fire warning system

No. 1 AC Transfer bus powers a single loop detector

20

How is a WHEEL WELL fire indicated

WHEEL WELL fire & master FiRE warning lights illuminate with steady fire bell

21

A smoke detection and fire suppression system is installed in the cargo compartment of the 500 aircraft

True

22

How is discharge of a lavatory fire extinguisher determined

Bottle nozzle tips change to an aluminum color

23

When the fire control panel test switch is placed to the FAULT/ INOP position, which lights should illuminate

Two MASTER CAUTION lights, the OVHt/DET annunciator, the FAULT light, and the APU DET/INOP light

24

During the FAULT/INOP test, the FAULT light does not come on but the APU DET INOP light does

?
The engine fault detection system has failed
?(apu)

25

The engine fire panel FAULT light illuminates during an overheat/fire test. This indicates

At least one engine has a faulty loop

26

On arrival at the aircraft you find the FAULT light illuminated prior to any system test. The loop selector switches are in the NORMAL position. Both fire warning loops on one engine have failed

True

27

Inflight with dual loop configuration selected, you observe the FAULT light illuminated on the fire warning panel. What has happened

Both loops on one engine have failed

28

Engine fire detection is powered from the

Battery bus

Hot Battery bus

30

If a fire is detected in the APU, the APU shuts down, the fire bottle discharges, and the fire bell silences after the fire bottle is discharged automatically

False

31

The WHEEL WELL fire detection system is DC powered

False

32

In flight, what happens if a single engine fire detector loop fails during dual loop operation

The loop is automatically deselected and fire warning capability is not lost on that engine

33

The OVHT/DET annunciator and the MASTER CAUTION lights are illuminated( triggered by)
