About Nellis Air Force Base

Nellis 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

Nellis Air Force Base is located in Las Vegas, Nevada, serving as a critical military aviation facility. Situated at an elevation of 1,870 feet MSL, the base supports extensive military training and operational requirements. Its strategic location and substantial runway infrastructure make it a key installation in the southwestern United States.

Flying Conditions

Weather conditions at Nellis AFB are predominantly excellent for flying, with VFR conditions present 96.9% of the time. The prevailing winds are from the northeast at an average of 7.1 knots, with temperature ranges from 1°C to 38°C. Pilots can expect highly stable flying conditions, with minimal risk of low visibility or challenging meteorological circumstances.

Notable Features

The airport features two substantial concrete runways, both exceeding 10,000 feet in length, which provide significant operational flexibility. Its location near Las Vegas offers a mix of desert terrain and relatively consistent atmospheric conditions. The base's dual runways (03L/21R and 03R/21L) are aligned similarly and demonstrate 100% favorable wind coverage with minimal average crosswind.

Approach Considerations

Both runways show identical wind characteristics, with an average crosswind of just 3.7 knots, indicating predictable approach conditions. October, December, and September represent the most favorable months for VFR operations. Pilots should anticipate stable approach environments with high visibility averages of 9.9 statute miles and minimal potential for meteorological disruptions.
