Excessive heat by fire or other heat sources expands an inert gas inside the fire-detection loop. The expansion of gas closes a pressure switch that sends a signal to illuminate the left or right ENGINE FIRE light.

False.

True.

Correct! Wrong!

The fire-extinguisher bottle contains:

Two individual firing cartridges (squibs).

Two individual firing valves.

One individual firing cartridge and one squibs.

One individual firing valve.

Correct! Wrong!

The bottle has also a safety relief valve that thermally relieves (discharges) if the internal bottle temperature rises above 99 deg.C (210 deg.F).

What indications are visible when the rotary TEST knob is placed in the FIRE WARN position?

BOTTLE ARMED PUSH lights illuminate.

Red L ENGINE FIRE, R ENGINE FIRE, and MASTER WARNING lights illuminate.

Fire bottle pressure is displayed on the multifunction display.

Confirms the fire bottle is serviced and full.

Correct! Wrong!

During the preflight inspection, sufficient engine fire bottle pressure can be determined by:

The absence of the ENG FIR BOTL SERV CAS message.

Checking to ensure that the engine fire bottle gauge is within the green arc.

Visual inspection of the bottle pressure gauge against the bottle pressure placard.

Successful completion of the engine fire position on the rotary test.

Correct! Wrong!

A successful test of the fire-detection system using the rotary TEST knob, or illumination of either BOTTLE ARMED light, will confirm that the fire bottle is serviced and full.

True.

False.

Correct! Wrong!

This test of the fire-detection system using the rotary TEST knob, or illumination of either BOTTLE ARMED light, does NOT confirm that the fire bottle is serviced and full. This can only be confirmed by a visual check of the bottle gauge and comparing the reading to a placard that correlates the acceptable pressure/temperature ranges.

A pressure sensor is at the end of the fire-detection loop. When the loop is heated by fire or a bleed air leak, the gas in the tube expands, activating the pressure sensor. This produces an electrical signal that provides a warning to the flightcrew. The signal is in the form of L or R ENGINE FIRE lights and MASTER WARNING lights.

False.

True.

Correct! Wrong!

The engine fire bottle (with two squibs) is:

In the tail compartment.

In the tail compartment and underneath the cabin.

Underneath the cockpit.

Underneath the cabin.

Correct! Wrong!

If the right side squib fails, fire protection is:

Not available to either engine.

Available through the rotary TEST knob.

Not available to the right engine.

Still available for both engines from the left side.

Correct! Wrong!

Pressing the R ENGINE FIRE light:

Disables the right generator.

Stops right fuel flow past the firewall.

All statements are correct.

Arms the fire bottle.

Correct! Wrong!

If the L ENGINE FIRE light extinguishes after moving the left throttle to idle, this indicates a possible:

Fuel leak.

Bleed-air leak.

Hydraulic leak.

Nitrogen leak.

Correct! Wrong!
