Aviation Calculators
Work with flight distance, time, speed, fuel, weight, altitude, runway and wind-related calculations and aviation unit conversions. These tools are intended for learning, preliminary estimates and reference checks. They are not a substitute for approved flight-planning systems, aircraft manuals, current weather data or qualified operational procedures.

About these aviation tools
These calculators are intended for educational, estimation and general planning use. Aviation performance, weight-and-balance, takeoff/landing and operational decisions should always use the aircraft-specific approved data, operating limitations and applicable procedures. Units such as nautical miles, feet and UTC are commonly used in aviation references. Always verify operational calculations against authoritative aircraft and regulatory sources.
