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!

Pressing the R ENGINE FIRE light:

Disables the right generator.

All statements are correct.

Arms the fire bottle.

Stops right fuel flow past the firewall.

Correct! Wrong!

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

Fire bottle pressure is displayed on the multifunction display.

Confirms the fire bottle is serviced and full.

BOTTLE ARMED PUSH lights illuminate.

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

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.

The fire-extinguisher bottle contains:

Two individual firing valves.

One individual firing cartridge and one squibs.

One individual firing valve.

Two individual firing cartridges (squibs).

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).

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

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

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

The absence of the ENG FIR BOTL SERV CAS message.

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

Correct! Wrong!

If the right side squib fails, fire protection is:

Not available to the right engine.

Still available for both engines from the left side.

Not available to either engine.

Available through the rotary TEST knob.

Correct! Wrong!

The engine fire bottle (with two squibs) is:

Underneath the cockpit.

Underneath the cabin.

In the tail compartment and underneath the cabin.

In the tail compartment.

Correct! Wrong!

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

Nitrogen leak.

Fuel leak.

Bleed-air leak.

Hydraulic leak.

Correct! Wrong!

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.

True.

False.

Correct! Wrong!
