About Greenville Downtown Airport

Overview

Greenville Downtown Airport serves the Greenville metropolitan area in South Carolina, providing critical aviation infrastructure for the region. Located at an elevation of 1,048 feet MSL, the airport offers two asphalt runways capable of supporting a variety of general aviation and light commercial operations. Its strategic positioning and dual runway configuration make it a key transportation asset for the local aviation community.

Flying Conditions

Pilots can expect predominantly favorable VFR conditions, with 77.8% of observations indicating good visual flying weather. The airport experiences a moderate temperature range from -7°C to 32°C, with prevailing northeast winds averaging 6.7 knots. Seasonal variations show October, November, and September as the most consistently good VFR months, with minimal low ceiling or visibility restrictions.

Notable Features

The airport features two parallel runways with different lengths: Runway 01/19 at 5,393 feet and Runway 10/28 at 3,998 feet. Both runways demonstrate excellent wind alignment, with 100% favorable wind coverage. The relatively low average crosswind of 3.8-4.7 knots provides consistent and predictable landing conditions for most aircraft operations.

Approach Considerations

Wind data indicates a consistent northeast wind pattern at 45 degrees, which typically favors Runway 01/19 for arrivals and departures. Pilots should anticipate calm conditions approximately 19.7% of the time, with visibility typically exceeding 9.3 statute miles. Occasional reduced visibility occurs in less than 3% of observations, with light fog present in 2.8% of reports.
