Rationale: Jet A and Jet A-1 are kerosene-based fuels used in turbine

engines including jets and turboprops.

• Which of the following is a key hazard associated with aviation fuel?
• Noise
• Flammability
• UV exposure
• Ergonomic strain

Rationale: Aviation fuels are highly flammable, making fire prevention and

proper handling critical.

• What personal protective equipment (PPE) is essential for fueling

operations?

• Hard hat only
• Gloves only
• Safety boots only

5. Before fueling an aircraft, a technician should always:

• Start the engines
• Check for fuel leaks and grounding
• Open all doors
• Remove all cargo 2 / 4

Rationale: Checking for leaks and ensuring the aircraft is properly

grounded prevents static discharge and fire hazards.

• What is the purpose of grounding an aircraft during fueling?
• To prevent corrosion
• To prevent static electricity sparks
• To improve fuel efficiency
• To keep the aircraft stable

Rationale: Grounding prevents the build-up of static electricity which can

ignite fuel vapors.

• Which system is used to pump fuel into an aircraft?
• Hydraulic system
• Electrical system
• Fuel hydrant or fuel truck system
• Cooling system

Rationale: Fuel hydrant systems or fuel trucks deliver fuel safely from

storage to the aircraft.

• What should a fueling technician do if they detect a fuel leak?
• Continue fueling slowly
• Ignore it
• Stop fueling and report immediately
• Wipe it with a rag 3 / 4

Rationale: Fuel leaks are a serious hazard; operations must stop

immediately and the issue reported.

• How is the proper type of fuel verified before fueling?
• Smell test
• Color comparison only
• Checking aircraft fuel specifications and fuel labels
• Pump it and check performance

Rationale: Using the wrong fuel type can cause engine failure; technicians

must verify aircraft specifications and fuel labels.

• What is a major environmental concern associated with aviation

fueling?

• Noise pollution
• Light pollution
• Fuel spillage and contamination
• Bird strikes

Rationale: Fuel spills can contaminate soil and water; proper containment

and spill procedures are critical.

• When transferring fuel from a truck to an aircraft, the technician

should:

• Keep the truck running
• Ensure both the truck and aircraft are grounded
