Definition
KEUG is the four-letter ICAO airport identifier for Mahlon Sweet Field (Eugene Airport) in Eugene, Oregon, USA. The 'K' prefix designates airports in the contiguous United States under the ICAO location indicator system, and 'EUG' is the underlying three-letter FAA/IATA identifier for the airport.
Plain English
KEUG is the official four-letter code that identifies Eugene Airport in Oregon when used in flight plans, charts, and avionics databases.
Context Anchor
A pilot may see KEUG when entering an airport into a GPS, reviewing an instrument procedure, or reading an avionics example that uses a real airport identifier.
Derivation
The 'K' prefix is the ICAO regional code for the contiguous United States. 'EUG' is the original three-letter FAA identifier derived from the city name Eugene. Combining them gives the four-letter ICAO form used for international flight planning and avionics systems.
Why Pilots Care
Ensures the correct airport and its instrument procedures are loaded into navigation equipment.
Intuition Check
KEUG is not a radio call sign, frequency, or waypoint name in this context. It is the specific airport identifier for Eugene Airport.
Example Sentence 1
We filed KSFO to KEUG with a planned RNAV arrival into Mahlon Sweet Field.
Example Sentence 2
