Definition
An aircraft that is flying toward an airport, fix, or specified location, typically arriving to land or transit through a defined area.
Plain English
Another aircraft that is heading in toward the airport or point you are at or near.
Context Anchor
You may see or hear this term in airport traffic discussions, radio calls, and safety guidance about watching for aircraft approaching the airport.
Derivation
"Inbound" combines "in" (toward) with "bound" (heading or going). The word "bound" in this sense comes from an old Norse word meaning "prepared to go." So inbound traffic literally means aircraft heading toward a place.
Why Pilots Care
Identifying inbound traffic is essential for maintaining separation and avoiding mid-air collisions, especially when entering, departing, or crossing an active traffic pattern.
Intuition Check
Inbound does not simply mean “nearby.” It means the aircraft is moving toward the airport, runway, or named point.
Example Sentence 1
Cessna 4-5-Romeo is inbound traffic from the north, ten miles out, inbound for landing runway 27.
Example Sentence 2
On the CTAF the instructor asked the student to report any inbound traffic entering from the north.
