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; an illustrative estimate to compare with your POH/AFM's maximum demonstrated crosswind
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, in gallons or litres; an illustrative estimate, not for flight planning
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; an illustrative estimate
Density Altitude Calculator
Estimate density altitude from pressure altitude and outside air temperature, with the ISA standard temp — see how hot-and-high conditions push it up; your POH/AFM charts give the performance
Weight & Balance Calculator
Add up every loading station's weight and moment to find your aircraft's total weight and centre of gravity; an arithmetic aid, with the aircraft's own W&B record and POH/AFM envelope as the authority
Flight Training Cost Calculator
Price a private pilot certificate from your own quotes: aircraft and instructor rates, dual, solo and ground hours, fees and kit, repriced at the 40-hour minimum and the FAA's average of about 75 hours
