Frequently asked questions
What is the runway length at KGSP?
Greenville Spartanburg International, KGSP, has a single runway, 04/22, measuring 11,001 feet long and 150 feet wide. The surface is a mix of asphalt and concrete, with concrete sections at the south and north ends and an asphalt center portion. This length supports the full range of business jet and airline traffic operating at the field. The published PCR value is 1050/F / B/X / T, reflecting a pavement built for heavy operations.
Is customs available at Greenville Spartanburg International (KGSP)?
Yes, CBP inspection services are available onsite at Greenville Spartanburg International, and the airport also holds a USDA compliance agreement. This combination allows international arrivals to clear both customs and agricultural inspection at the field itself. Crews should still coordinate arrival details with airport operations given the traffic volume the field handles. GSP is a towered, public-use airport in Greer, South Carolina, operating with full-time attendance.
Are there turn restrictions for heavy aircraft at KGSP?
Yes. At Greenville Spartanburg International, heavy aircraft are restricted from making turns greater than 90 degrees on the asphalt portions of the runway or on parallel taxiway Lima, as well as on taxiways D, E, F, and G, unless directed otherwise by the tower. This restriction is tied to the runway's mixed surface construction, where the center 6,551-foot section is asphalt while the ends are concrete. Crews operating heavy airframes at KGSP should brief this limitation before taxi to avoid a nonstandard turn on unsuitable pavement.
What happens when the tower is closed at KGSP?
When the air traffic control tower at Greenville Spartanburg International is closed, pilots must activate the MALSR on runway 22, the centerline lighting on runway 22, and the HIRL for runway 04/22 using the CTAF. Separately, ARFF communications shift to frequency 120.1 during tower-closed hours. Pilots requiring a clearance delivery and finding Greer Approach closed should contact Atlanta ARTCC instead. These procedures apply specifically to non-towered hours at GSP.
Is there a weight-related procedure for GA or military aircraft at KGSP?
Yes. Any general aviation or military aircraft heavier than 120,000 pounds arriving at Greenville Spartanburg International requires prior permission, and the crew must contact airport operations before the flight. This applies regardless of aircraft type once the weight threshold is crossed. The requirement exists alongside other ramp and taxiway routing restrictions at KGSP tied to specific operators, including guidance for PSA and ACES MRO traffic to avoid certain ramp areas without prior coordination with airport operations.
