Aviation Tools

All aviation calculations in one place — density altitude, TAS, wind, crosswind, fuel, and more.

Calculate pressure altitude from field elevation and altimeter setting.

Calculate pressure altitude and density altitude from field elevation, altimeter setting, and temperature.

Calculate TAS from calibrated airspeed, pressure altitude, and outside air temperature.

Calculate IAS from true airspeed, pressure altitude, and outside air temperature.

Calculate wind correction angle, heading, and ground speed from course, airspeed, and wind.

Calculate headwind, tailwind, and crosswind components from runway heading and wind conditions.

Calculate fuel required and endurance from fuel flow rate and flight time.

Solve for any missing value given two of: distance, ground speed, and time.

Convert between aviation units — nautical miles, knots, inHg, flight levels, gallons, and more.

Calculate ICAO cold temperature altitude corrections for instrument approaches. Enter aerodrome elevation, OAT, and published altitudes.

Interpolate between two known data points to find a missing value. Essential for reading aviation performance charts and tables.

Calculate rate of climb/descent, gradient percentage, and distance required for takeoff and approach procedures.

Calculate air time and flight time from engine start, takeoff, landing, and engine stop — in HH:MM and decimal format.
