Which Fire Extinguisher Class would we use on a gasoline fire?

• Class A

• Class D

• Class C

• Class B

In the Spot Detector type fire detection system, Figure 16-01 If one spot detector was to fail in the open position, would the fire detection system: 1. Function to detect a fire 2. Function test normally

• The System would not function but would test proper operation

• System would function normally, and would test normal operation

• System would function properly with slight limitation and the system would test normally

• The system would not function, nor would it test properly and would show system failure

A large aircraft APU fire bottle is:

• Powered from the switched Battery Bus

• Powered from the Hot Battery Bus

• Powered by a combination of inert gases and proprietary chemicals

• Powered from a master switch

In a HRD fire extinguishing systems, there are 2 blowout discs. What are their purposes?

• The Red Disc indicates a normal use of the extinguishing system, the yellow indicates a thermal blowout

• The Yellow disc indicates normal system charge, the red disc indicates a system overcharg

• There is no difference. The colours are at the manufactures option

• A missing yellow disc indicates a normal use of the extinguishing system, a missing red indicates a thermal blowout

The primary purpose of a fuel tank sump is to provide a:

• Positive supply of pressurized fuel to the aircraft engine.

• Reserve supply of fuel to allow the aircraft to land safely if the main fuel tank runs dry.

• Means of separating out vapors from the fuel.

• Place where water and dirt accumulation in the tank can collect and be drained.

The decal or placard located by the filler port of a piston-powered aircraft says 80/87. What grade fuel cannot be used in this aircraft?

• 100 LL.

• 100/130.

• 80/87.

• Mogas.

The probe of a capacitance type fuel quantity transmitter is essentially:

• A float actuated variable capacitor.

• A capacitor with fuel and air acting as a dielectric.

• A capacitor with fuel and air acting as a plate.

• A temperature compensated variable potentiometer.

Why is it necessary to vent all aircraft fuel tanks?

.

• To ensure a positive head of pressure for a submerged boost pump

• It is not necessary to vent fuel tanks, which are pressure refueled.

• The statement is false as pressurized fuel systems do not require a vent.

• To limit pressure differential between the tank and atmosphere.

What type of fuel boost pump has a means of separating vapors from the fuel before the fuel enters the rest of the fuel system?

• Gear type pump.

• Sliding vane type pump.

• Centrifugal type pump.

• Ejector type pump.

A typical large transport aircraft fuel manifold system allows how many of the following?

(1)All tanks can be serviced through a single connection.

(2) Any engine can be fed from any tank.

(3) All engines can be fed from all tanks simultaneously.

(4) A damaged tank can be isolated from the rest of the fuel system.

• 1 and 2.

• 2 and 4

• 1, 2, 3, and 4.

• 1, 2, and 3.
