About Killeen Regional Airport / Robert Gray Army Airfield

Killeen Regional Airport / Robert Gray Army Airfield is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

Killeen Regional Airport / Robert Gray Army Airfield serves as a strategic medium-sized airport located at Fort Cavazos, Texas, with an elevation of 1,015 feet MSL. The airport supports both military and civilian aviation operations, positioned centrally in Texas with coordinates 31.067200, -97.828903. Its primary runway 15/33 provides a substantial 10,000-foot paved and marked (PEM) surface.

Flying Conditions

Weather conditions at KGRK are predominantly visual flight rules (VFR), with 70.8% of observations supporting clear flying conditions. Seasonal temperatures range from -3°C to 37°C, with an average of 18.2°C, offering relatively moderate operational environments. Wind patterns are primarily from the south at 180°, averaging 7.9 knots, with maximum gusts up to 36 knots and calm conditions occurring 15.7% of the time.

Notable Features

The airport's single runway 15/33 demonstrates excellent wind alignment, with favorable wind conditions 100% of the time and an average crosswind component of just 3.8 knots. Its strategic location and substantial runway length make it suitable for a variety of aircraft types, from small general aviation to larger military and commercial platforms. The surrounding terrain is typical of central Texas, with relatively flat topography.

Approach Considerations

September, October, and November represent the best months for VFR flying, with consistently favorable weather conditions. Pilots should anticipate mostly clear skies, with visibility averaging 8.9 statute miles and limited occurrences of restricted visibility (below 3SM in only 1.9% of observations). The predominant southern winds suggest runway 33 may offer slightly more favorable approach conditions during typical wind patterns.
