About Cyril E. King Airport

Overview

Cyril E. King Airport serves Charlotte Amalie, located in the U.S. Virgin Islands, functioning as a critical medium-sized airport for regional and international transportation. Situated at 23 feet above mean sea level with coordinates 18.337091, -64.977251, the airport provides essential aviation infrastructure for the Caribbean region.

Flying Conditions

Weather conditions at TIST are predominantly favorable for visual flight rules (VFR), with 94.2% of observations supporting VFR operations. The airport experiences consistent easterly winds averaging 8.4 knots, with temperatures ranging from 21°C to 34°C and an average visibility of 9.8 statute miles. January, November, and December represent the most consistently good VFR months for operations.

Notable Features

The airport features a single runway (10/28) measuring 7,000 feet with an asphalt surface. Wind conditions heavily favor runway alignment, with 100% wind compatibility and an average crosswind of only 3.5 knots. The geographic location in the Caribbean creates a relatively stable meteorological environment with minimal adverse weather interruptions.

Approach Considerations

Runway 10/28 presents predictable approach conditions, with easterly winds consistently supporting operations. Pilots can expect minimal meteorological challenges, with IFR conditions occurring in less than 1.2% of observations. The low occurrence of low visibility events (fog at 0%, visibility below 3SM at 0.5%) suggests generally reliable visual approach opportunities.
