Aviation calculators

Airspeed, wind, fuel burn, density altitude and weight and balance, plus descent planning, climb gradient and engine-out glide range for pilots.

Top of descentHow far out to start down for a given descent angle, with the rate of descent and the time it takes.Wind correction angleThe heading to fly to hold a track in a crosswind, with the groundspeed that results and the time for a given leg.Climb gradientConverts a rate of climb and groundspeed into a climb gradient in feet per nautical mile, and checks it against a required departure gradient.Glide distanceHow far an aircraft glides from a given height at its best glide ratio, adjusted for a headwind or tailwind, and the height needed to reach a field.True Airspeed EstimateQuick true airspeed estimate from indicated airspeed and altitude, the pilot rule of thumb.Runway Crosswind & Headwind ComponentSplits wind into crosswind and headwind/tailwind for a given runway heading and wind direction.Fuel Burn Endurance & RangeFlight endurance and still-air range from usable fuel, burn rate and cruise speed.Density Altitude EstimateQuick density altitude estimate from pressure altitude and outside air temperature.Weight & Balance (Centre of Gravity)Total weight and centre of gravity from up to four weight-and-arm stations.
