20 questions
Question 1: For pressurised aeroplanes operating above 25 000 ft, the total number of oxygen dispensing units and outlets provided for passengers must exceed the number of seats by exactly 5%, with these extra units concentrated near emergency exits.
A. Ano
B. Ne
Explanation: According to OPS 1.770, Appendix 1, 2.(iii) and (iv), for aeroplanes operating above 25 000 ft, the total number of oxygen dispensing units and outlets must exceed the number of seats by at least 10%, not exactly 5%. Furthermore, these extra units are required to be evenly distributed throughout the cabin, not concentrated near emergency exits.
Question 2: According to the provided safety precautions, what are the potential effects of moisture coming into contact with gaseous oxygen within an aircraft system?
A. It can cause corrosion and the possibility of valves freezing.
B. The oxygen will probably smell "bad" when used.
C. It will support combustion more fiercely than air.
D. It will lead to a severe chemical reaction and spontaneous combustion.
Explanation: The study materials state: "Any moisture present will react with gaseous oxygen and can cause corrosion and the possibility of valves freezing. The oxygen will probably smell "bad" when used." The other options describe properties of oxygen itself or reactions with other substances like oil/grease, not specifically moisture.
Question 3: Is it a required procedure for the aircraft to be bonded (grounded) to the fuelling equipment using dedicated wires and clips before fuelling commences?
A. Ano
B. Ne
Explanation: Before fuelling commences, the aircraft should be bonded (grounded) to the fuelling equipment using dedicated wires and clips. Reliance must not be placed upon conductive hoses for effective bonding.
Question 4: What is the primary function of a collector tank (feeder box) in an aircraft fuel system?
A. To equalize air pressure above the fuel with ambient pressure.
B. To provide a constant supply of submerged fuel for the booster pumps.
C. To prevent structural damage from over-pressurization of the fuel tank.
D. To measure fuel volume by varying electrical resistance with a float.
Explanation: The study materials state that booster pumps are fitted in a collector tank or feeder box which always holds a measured quantity of fuel to allow the pumps to be continually submerged, thereby preventing pump cavitation due to attitude changes of the aircraft.
Question 5: An ideal fuel is required to be non-corrosive.
A. Ano
B. Ne
Explanation: The study materials list 'Non-corrosive' as one of the main requirements for an ideal fuel.
