Which statement best describes a Ground Service Request (GSR)?

• A. A request to air traffic control for a new route
• B. A request to crew for rest breaks
• C. A request to ground handlers for services such as catering, cleaning, or fueling
• D. A request to passengers for seat changes

Answer: (C)

A Ground Service Request is a way to coordinate on-ground services for an aircraft while it’s parked at the airport. It’s a request sent to the ground handling team to arrange what the aircraft needs between flights—such as catering, cabin cleaning, fueling, baggage handling, or other support tasks required to prepare the plane for its next departure. This is about services provided on the ground, not movements in the air or decisions about passengers.

So the statement describes asking ground handlers for services like catering, cleaning, or fueling, which is exactly what a Ground Service Request is used for. It’s different from requests to air traffic control for routing, from crew rest or scheduling matters, and from passenger seat changes, which fall outside ground service provisioning.
