Frequently asked questions
What runways does KGMU offer and how long is the main strip?
Greenville Downtown Airport, KGMU, operates two paved runways. Runway 01/19 is the primary strip at 5,393 feet long and 100 feet wide, with an asphalt surface. Runway 10/28 measures 4,000 feet long and 80 feet wide, also asphalt. Two 50-by-50-foot concrete helipads, H1 and H2, are also available. Runway 01 includes an EMAS arresting system at its departure end for overrun protection.
Is customs available on-site at Greenville Downtown Airport?
Greenville Downtown Airport, KGMU, does not have customs service on-site. The nearest customs-equipped airport is KGSP, Greenville-Spartanburg International, located approximately 7.07 nautical miles away. Flight crews requiring customs clearance should plan to route through that facility rather than KGMU. KGMU is a towered public airport with fuel service including 100LL and Jet A, but international arrival processing is not part of its on-field capability.
Are there weight restrictions on runway 10/28 at KGMU?
Yes, Runway 10/28 at Greenville Downtown Airport carries an operating restriction tied to taxiway use. Aircraft over 12,500 pounds are not permitted on taxiways C or D while aircraft are operating on Runway 10/28. Conversely, when aircraft are using taxiways C or D, Runway 10/28 itself is restricted to small aircraft under 12,500 pounds. Dispatchers planning operations on this crosswind runway at KGMU should account for this weight-based sequencing restriction.
What lighting is available at Greenville Downtown Airport when the tower is closed?
At Greenville Downtown Airport, KGMU, several lighting systems can be pilot-activated over CTAF when the air traffic control tower is closed. These include MALSF on Runway 01, REIL on Runway 19, HIRL on Runway 01/19, and perimeter and taxiway lights at the two helipads. However, REIL on Runway 28, PAPI on Runways 01, 19, and 28, and MIRL on Runway 10/28 are unavailable whenever the tower is closed. Crews should plan approaches accordingly during non-towered hours.
