Aviation Tools & Calculators
Free, practical tools for every flight — measure the great-circle distance, break down a crosswind, plan fuel and flight time, check density altitude, and run your weight and balance before you fly.
Great-Circle Distance Calculator
Get the great-circle distance between two airports or coordinates in nautical miles, kilometres, and statute miles — the shortest track over the globe, the way an aircraft actually flies
Crosswind Calculator
Break a reported wind into its crosswind and headwind components for any runway heading, plus the wind angle — check it against your aircraft's demonstrated limit before takeoff or landing
Fuel Burn Calculator
Estimate trip fuel, reserve fuel, and total fuel for a leg from its distance, groundspeed, fuel-flow rate, and a reserve requirement — quick preflight planning in gallons or litres
Flight Time Calculator
Estimate block time for a leg from its distance, groundspeed, and a taxi buffer — airborne minutes plus the total in clean hours and minutes for fast flight planning
Density Altitude Calculator
Estimate density altitude from pressure altitude and outside air temperature, with the ISA standard temp — see how hot-and-high conditions rob takeoff and climb performance
Weight & Balance Calculator
Add up every loading station's weight and moment to find your aircraft's total weight and centre of gravity — the preflight check that keeps you inside the loading envelope
