Definition
The in-flight transfer of fuel from one aircraft (the tanker) to another (the receiver) through a connecting hose or boom, allowing the receiving aircraft to extend its range, endurance, or mission time without landing.
Plain English
One aircraft passes fuel to another while both are still flying. They link up in the air through a hose or boom, fuel flows across, and the receiving aircraft can keep going without having to land and refuel.
Context Anchor
You may see this term in flight planning information, chart notes, or traffic advisories involving military aircraft operations.
Derivation
Aerial comes from the Latin aerius meaning 'of the air.' Refueling simply means filling with fuel again. Together: filling with fuel again, in the air.
Why Pilots Care
Extends aircraft range and endurance without landing, which matters for military missions and for civil pilots who may operate near tanker routes or training areas.
Intuition Check
Aerial refueling does not mean stopping at an airport to take on fuel. It means fuel is transferred from one aircraft to another while they are flying.
Example Sentence 1
The controller advised the pilot to remain clear of the published aerial refueling track active at FL250.
Example Sentence 2
Air traffic control cleared the fighter to the refueling track so it could complete aerial refueling before returning to base.
