Aviation
Flight planning calculators for pilots and students: crosswind component, true airspeed, fuel burn, glide ratio, rate of climb and top of descent, with the rules of thumb explained.
Crosswind Component Calculator
Calculate the crosswind and head or tailwind components for a runway from wind speed and direction. Free, fast and runs in your browser.
Fuel Burn Calculator
Calculate fuel required, endurance and range from your fuel burn rate, flight time, fuel onboard and groundspeed. Free pilot fuel planning tool.
Glide Ratio Calculator
Calculate glide ratio and glide distance from altitude. Enter a ratio or a known glide, plus your height above ground. Free pilot glide calculator.
Rate of Climb Calculator
Calculate time to climb and climb gradient in feet per nautical mile from your altitude to gain, rate of climb and groundspeed. Free pilot tool.
Top of Descent Calculator
Calculate your top of descent point, descent rate and gradient from altitude to lose, groundspeed and angle. Uses the handy 3 to 1 rule of thumb.
True Airspeed Calculator
Estimate true airspeed from indicated airspeed using the 2 percent per 1000 feet rule of thumb. Free pilot calculator that runs in your browser.
