About John Murtha Johnstown Cambria County Airport
Overview
John Murtha Johnstown Cambria County Airport serves the Johnstown region in Pennsylvania, providing a critical medium-sized airport facility for regional aviation operations. Located at an elevation of 2,284 feet MSL, the airport offers three asphalt runways with varying lengths, accommodating diverse aircraft types and operational requirements.
Flying Conditions
Weather conditions at KJST demonstrate significant variability, with visual flight rules (VFR) prevailing 47.3% of the time and marginal VFR conditions occurring 31.6% of observations. Wind patterns predominantly originate from the west at an average of 10 knots, with temperatures ranging from -21°C to 27°C and average visibility around 8.4 statute miles. Pilots should anticipate the most favorable visual flying conditions during September, October, and November.
Notable Features
The airport features three runways: 05/23 (4,386 ft), 10/28 (3,700 ft), and 15/33 (7,003 ft), providing multiple landing options for different wind conditions and aircraft capabilities. All three runways demonstrate 100% favorable wind alignment, with relatively low average crosswind components ranging from 4.6 to 7.5 knots. The airport's higher elevation and geographic location suggest potential terrain and atmospheric considerations for approach and departure.
Approach Considerations
Given the predominant westerly winds, pilots should be prepared for wind considerations during approaches and landings. The longest runway (15/33 at 7,003 ft) offers the most flexibility for larger aircraft and challenging conditions. Statistical data indicates potential challenges with reduced visibility, with 5.7% of observations showing visibility below 3 statute miles and 6.3% experiencing fog conditions.
