b. Detector switch in NORMAL – indicates both detector loops for an engine have failed
c. Detector switch in NORMAL – indicates a single loop failure has occurred
d. None of the above

Answer 3

Detector switch in NORMAL – indicates both detector loops for an engine have failed

Question 4

When the Engine Fire Extinguisher discharges, the L or R BOTTLE DISCHARGE light illuminates _________ .

a. Immediately after the engine fire switch is rotated
b. Immediately after the arm switch is pushed
c. Immediately after both the engine fire switch is rotated and the bottle has discharged
d. A few seconds after the engine fire switch is rotated

Answer 4

Immediately after the engine fire switch is rotated

Reference: FRM 8.2.2.2

Question 5

During a Cargo Fire TEST, the DETECTOR Fault light will illuminate if __________ .

a. One or more detectors in the loop(s) has failed
b. Will not illuminate as it is inhibited on the ground
c. All the detectors in the loop(s) have failed
d. None of the above

Answer 5

One or more detectors in the loop(s) has failed

Reference: FRM 8.2.8.1

Question 6

During a cargo fire test, the fire warning bell sounds, both master fire warning lights illuminate and ____________ .

a. Extinguisher lights illuminate, FWD and AFT cargo fire warning lights illuminate immediately, cargo fire bottle DISCH light illuminates
b. Extinguisher lights illuminate, FWD and AFT cargo fire warning lights illuminate when all detectors respond to the fire test, cargo fire bottle DISCH light illuminates
c. FWD and AFT cargo fire warning lights illuminate when all detectors respond to the fire test, cargo fire bottle DISCH light illuminates
d. Extinguisher lights illuminate, FWD and AFT cargo fire warning lights illuminate when all detectors respond to the fire test, cargo fire bottle DISCH light flashes

Answer 6

Extinguisher lights illuminate, FWD and AFT cargo fire warning lights illuminate when all detectors respond to the fire test, cargo fire bottle DISCH light flashes

Reference: FRM 8.2.8.1

Question 7

d. -800 ETOPs have 1 bottle, -800 domestic have 2 bottles

Answer 7

-800 ETOPs have 2 bottles, -800 domestic have 1 bottle

Reference: FRM 8.2.5.3

Question 8

To determine the specific inoperative engine fire detector loop, select A or B on the OVHT DET switch, push the test switch and observe _________ .

a. The FAULT light remains extinguished and both ENG OVERHEAT lights and engine fire
warning switches illuminate, that respective loop is good.
b. If the FAULT light illuminates and one of the ENG OVERHEAT lights and corresponding engine
fire warning switch remain extinguished, there is a fault in the respective loop of the detection
system of that engine.
c. If the FAULT light illuminates and both of the ENG OVERHEAT lights and corresponding engine
fire warning switch illuminate, there is a fault in the respective loop of the detection system of
that engine.
d. Both a and b

Answer 8

Both a and b
