(Day 09) Refueling and Defueling

What precaution should be taken if a fuel truck has recently been refilled or driven over a bumpy road?

Fuel should be allowed to settle for a few hours.

Which of the following best describes the main precaution to take when fueling an aircraft outside a hangar?

Preventing fuel vapors from accumulating to avoid fire hazards.

How should a fuel truck be positioned relative to the aircraft during refueling?

Parallel to the wings and in front of the fuselage.

What is the primary purpose of bonding cables during defueling?

To prevent static electricity buildup.

Why is it necessary to use a ladder or designated safe areas when accessing fueling ports?

To avoid damaging the aircraft.

What should be done if a fueling nozzle shows signs of leaking or malfunctioning?

It should be replaced immediately.

Why is it important to wear cotton clothing while handling fuel?

Cotton does not promote static electricity buildup.

How should larger fuel spills be managed to reduce the risk of fire?

Flooded with water to dissipate the fuel.

Why is it important to verify the correct fuel type before fueling an aircraft?

To ensure proper engine performance and safety.

Why is it essential to have fire extinguishers on hand during the fueling and defueling processes?

When using over-the-wing refueling, what is a critical step to avoid damage to the aircraft?

Keeping the fuel nozzle clean.

What should be done if fuel contamination is suspected during defueling?

Store the contaminated fuel separately and dispose of it properly.
