About Bert Mooney Airport

Overview

Bert Mooney Airport serves the Butte, Montana region as a medium-sized airport situated at a high elevation of 5,550 feet MSL. Located at coordinates 45.954800, -112.497002, the airport provides critical aviation infrastructure for southwestern Montana, supporting regional transportation and local aviation needs.

Flying Conditions

Pilots can expect predominantly VFR conditions 86% of the time, with marginal and instrument conditions occurring less frequently. The airport experiences significant temperature variation, ranging from -18°C to 26°C, with an average temperature of 2.7°C. Prevailing winds from the northwest at an average of 6.6 knots, with occasional gusts up to 31 knots, characterize the local wind environment.

Notable Features

The airport features three asphalted runways with substantial length, offering multiple landing options. Runway 15/33 is the longest at 9,001 feet, providing excellent operational flexibility for various aircraft types. The high elevation and surrounding terrain suggest potential density altitude considerations, particularly during warmer months.

Approach Considerations

All three runways demonstrate 100% favorable wind alignment, with modest average crosswind components (4.5kt, 4kt, and 3.5kt respectively). Visibility averages 9.5 statute miles, with minimal instances of reduced visibility (below 3SM occurring only 1.8% of the time). September, January, and November represent the most consistently favorable VFR months for operations.
