About Altoona Blair County Airport

Overview

Altoona Blair County Airport serves as a medium-sized airport located in central Pennsylvania, situated at an elevation of 1,503 feet MSL. The airport provides aviation services to the Altoona metropolitan area, supporting both general aviation and potential regional commercial operations. Its strategic location and dual-runway configuration offer flexibility for aircraft operations in the region.

Flying Conditions

Pilots can expect predominantly favorable VFR conditions at this airport, with 64% of observations reporting visual flight rules. Seasonal temperature variations are significant, ranging from -19°C to 29°C, which can impact aircraft performance and operational considerations. Wind patterns are predominantly westerly at 270° with an average speed of 9.1 knots, and calm conditions occur 21.9% of the time.

Notable Features

Both runways (03/21 and 12/30) are asphalt-surfaced with substantial lengths of 5,466 and 3,668 feet respectively. The airport demonstrates excellent wind alignment, with both runways showing 100% favorable wind conditions and relatively low average crosswind speeds (6.6 knots for 03/21 and 4.9 knots for 12/30). September, October, and November represent the most consistent VFR flying months.

Approach Considerations

Visibility averages 8.9 statute miles, with only 2.9% of observations showing visibility below 3 miles and 2.7% experiencing fog conditions. Pilots should be prepared for potential reduced visibility, particularly during seasonal transitions. The dual-runway configuration provides operational flexibility, allowing selection of the most wind-aligned runway based on current conditions.
