About McChord Air Force Base
McChord Air Force Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.
Overview
McChord Air Force Base (KTCM) is a medium airport located in Tacoma, Washington, serving critical military aviation operations. Situated at 322 feet mean sea level, the base features two paved runways that support military and strategic airlift missions in the Pacific Northwest region.
Flying Conditions
The airport experiences diverse weather conditions, with Visual Flight Rules (VFR) prevailing 54.3% of the time. Pilots should anticipate significant variability, including Marginal VFR (20.9%) and Instrument Flight Rules (10.9%) conditions. Temperature ranges from -4°C to 33°C, with an average of 7.9°C, and wind patterns predominantly from the south at an average of 7.2 knots.
Notable Features
Located at coordinates 47.137699, -122.475998, McChord AFB offers two runways: a primary 10,108-foot runway and a secondary 3,000-foot runway. Both runways demonstrate consistent wind alignment, with 100% favorable wind conditions and an average crosswind of 4.6 knots. Visibility averages 9 statute miles, with occasional reduced visibility due to fog (10.4% occurrence).
Approach Considerations
September through November represent the most favorable VFR months for operations. Pilots should be prepared for potential reduced visibility, with 2.5% of observations showing visibility below 3 statute miles. The prevailing south winds and minimal crosswind make both runways consistently accessible, with calm conditions present 41.9% of the time.
