About Grissom Air Reserve Base

Overview

Grissom Air Reserve Base is located in Peru, Indiana, serving as a medium-sized military airfield. The base sits at an elevation of 812 feet MSL and supports critical air mobility and reserve operations in the midwest region. Its strategic location and substantial 12,501-foot runway make it a significant regional aviation facility.

Flying Conditions

Pilots can expect predominantly favorable flying conditions, with 53.4% of observations reporting VFR weather. The base experiences moderate wind conditions, with a prevailing westerly wind at an average of 10.1 knots. Temperature variations are significant, ranging from -19°C to 32°C, which can impact aircraft performance and flight planning.

Notable Features

The airport features a single runway (05/23) with an asphalt surface, capable of handling substantial aircraft operations. Wind analysis shows 100% runway favorability, with an average crosswind of 6.3 knots. Visibility is generally excellent, averaging 9 statute miles, with only 1.9% of observations reporting visibility below 3 miles.

Approach Considerations

September through November represent the most consistent VFR months for operations. Pilots should anticipate westerly winds and prepare for potential temperature-related performance considerations. The long runway provides substantial operational flexibility, and the low percentage of IFR conditions (14.5%) suggests generally reliable approach and landing environments.
