Question 1: The maximum permissible defueling pressure marking is required near the fuel filler opening of reciprocating-engine-powered aircraft.

A. Ano

B. Ne

Explanation: The maximum permissible defueling pressure marking is required near the filler opening of fuel tanks on turbine-powered aircraft, not reciprocating-engine-powered aircraft. For reciprocating-engine-powered aircraft, the markings are the word “AVGAS” and the minimum grade of fuel.

Question 2: The maximum permissible fueling supply pressure marking is required near the filler opening of fuel tanks on reciprocating-engine-powered aircraft.

A. Ano

B. Ne

Explanation: The maximum permissible fueling supply pressure marking is required near the filler opening of fuel tanks on turbine-powered aircraft, not reciprocating-engine-powered aircraft.

Question 3: The dye in jet fuel is primarily used to indicate a fuel leak on a turbine-powered aircraft.

A. Ano

B. Ne

Explanation: The study materials state that the dye in gasoline indicates a fuel leak on a reciprocating-engine powered aircraft, not primarily on a turbine-powered aircraft with jet fuel.

Question 4: A drip gage permits a mechanic to check the fuel level in an aircraft's tank from the bottom of the tank.

A. Ano

B. Ne

Explanation: The drip gage allows a mechanic to check the fuel level in a tank from the bottom of the tank.

Question 5: Is the purpose of a fuel heater in a turbojet aircraft to prevent water from freezing on the fuel filters?

A. Ano

B. Ne

Explanation: Turbojet aircraft operate at low temperatures where water can precipitate out of the fuel and freeze on the filters. A fuel heater keeps the fuel temperature above freezing to prevent this issue, ensuring fuel flow to the engines.
