  1. What type of fuel do most commercial jet aircraft use at US airports?

    Answer: Jet-A

    Jet-A is the standard kerosene-based turbine fuel used by commercial jet aircraft at US airports, characterized by its high flash point and low freeze point.

  2. Before connecting a fuel hose to an aircraft, what is the primary safety step to prevent static discharge ignition?

    Answer: Bond the fuel truck to the aircraft with a grounding cable

    Bonding the fuel vehicle to the aircraft equalizes electrical potential between the two, eliminating the risk of a static spark that could ignite fuel vapors.

  3. Which color identifies Jet-A fuel dispensing equipment at US airports?

    Answer: Black

    Black is the standard color coding for Jet-A fuel hoses, nozzles, and fuel trucks at US airports to help prevent dangerous misfueling with other fuel types.

  4. What is a 'deadman control' on a fuel nozzle?

    Answer: A spring-loaded handle that automatically stops fuel flow when released

    A deadman control is a spring-loaded handle on the fueling nozzle that automatically stops fuel flow when released, preventing uncontrolled fuel spills if the operator loses control.

  5. During aircraft fueling operations, which action is strictly prohibited within 50 feet of the aircraft?

    Answer: Smoking or use of open flames

    Smoking and open flames are strictly prohibited within 50 feet of an aircraft during fueling because fuel vapors are highly flammable and could be ignited, causing a fire or explosion.

  6. What is the primary purpose of drawing a fuel sample (sump check) before fueling an aircraft?

    Answer: To detect water and sediment contamination

    A sump check draws fuel from the lowest point of the fuel tank or truck to visually inspect for water (appearing as droplets or cloudiness) and sediment that could damage aircraft engines.

  7. Under what atmospheric condition must outdoor aircraft fueling operations be immediately suspended?

    Answer: Active lightning within the immediate airport area

    Fueling must be suspended during nearby lightning activity because an electrical discharge near fuel vapors creates an extreme fire and explosion hazard.
