About Allegheny County Airport

Overview

Allegheny County Airport serves the Pittsburgh metropolitan area as a medium-sized airport situated at 1252 feet above mean sea level. Located at coordinates 40.354401, -79.930199, the airport provides critical general aviation infrastructure for southwestern Pennsylvania. Its three runways, including two concrete runways over 3800 feet long, support diverse aviation operations.

Flying Conditions

Weather observations reveal complex flying conditions with significant variability. Pilots can expect Visual Flight Rules (VFR) conditions approximately 60% of the time, while Marginal VFR conditions occur in about 23% of observations. Temperature ranges dramatically from -18°C to 28°C, with prevailing westerly winds averaging 8 knots and occasionally reaching 27 knots. September through November represent the most consistently favorable VFR months.

Notable Features

The airport features three runways: a primary 6501-foot runway (10/28), a secondary 3825-foot runway (13/31), and a smaller 47-foot helicopter runway. Both primary runways demonstrate 100% wind favorability, with modest average crosswind conditions of 4.8 and 5.4 knots respectively. Visibility averages 8.4 statute miles, with occasional reduced visibility periods affecting approximately 5.6% of observations.

Approach Considerations

Pilots should anticipate westerly winds as the predominant meteorological condition, with calm conditions occurring in 9.7% of observations. Approach planning should consider potential reduced visibility scenarios, as fog affects approximately 5.4% of recorded periods. The comprehensive runway configuration provides multiple landing options adaptable to prevailing wind conditions.
