Wind and Navigation

These calculators answer the questions that come up while planning a leg: how much of the wind is across the runway, what heading holds the course, how far and how long it is, and where to start the descent.

Tools in this group

Airport Distance Calculator. Enter two to ten airports to get the great-circle distance, the initial true course and the time for every leg, and the total for the route.

Crosswind Calculator. Enter the runway number and the wind to get the crosswind and headwind components, the side the wind comes from, and the effect of the gust.

E6B Flight Computer. Pick a mode, enter the values you know and get the answer with the working: time, speed and distance, fuel, wind triangle, conversions, gradient or turn bank angle.

Flight Time Calculator. Work out the flight time between two airports from cruise speed, wind and extra minutes, or the block time between a departure and an arrival clock time.

Top of Descent Calculator. Enter your altitude, the altitude to reach, ground speed and descent angle to get the distance needed, the descent rate and where to start down.

Wind Correction Angle Calculator. Enter the true course, the true airspeed and the wind to get the wind correction angle, the true heading to fly, the ground speed and the time for the leg.
