Equipment Operation Flashcards

A baggage tug is pulling a train of carts. What is the typical maximum number of carts allowed at many US airports?

Answer: Four

Many airports and airlines limit baggage trains to around four carts to keep them controllable and avoid swing on turns.

Why must cart trains take wide, slow turns on the ramp?

Answer: Trailing carts cut inside the tug's path and can strike objects

Towed carts track inside the tug's turning path, so tight turns risk hitting aircraft, equipment, or people.

What is the purpose of a preconditioned air (PCA) unit at the gate?

Answer: To heat or cool the cabin without running the APU

PCA supplies conditioned air to the cabin, reducing APU use, fuel burn, and emissions.

Which device is used to start an aircraft engine when the APU is inoperative?

Answer: Air start unit (ASU)

An air start unit provides high-pressure air to turn the engine's pneumatic starter.

When operating a lavatory service truck, why must the waste hose be connected before opening the drain valve?

Answer: To prevent waste spilling onto the ramp and aircraft

Connecting first ensures waste flows into the truck tank instead of onto the ramp or the operator.

Potable water and lavatory service equipment must be kept separate primarily to prevent what?

Answer: Cross-contamination of drinking water

Sanitation rules require separate equipment and handling so waste never contaminates the aircraft's drinking water.

Before operating unfamiliar GSE, what is required of a ramp employee?

Answer: Training and authorization on that specific equipment

Operators must be trained and qualified on each equipment type before using it on the ramp.
