AviCalc
A fast, dependable flight computer for your pocket.
AviCalc brings the everyday math of flying into one clean interface: wind correction, fuel burn, weight and balance, time-speed-distance, and unit conversion. It works entirely offline, so it is just as usable at 8,000 feet as it is on the ramp.
What it does
Everyday flight math
Wind correction angle, groundspeed, true airspeed, density altitude, and time-speed-distance solved in a couple of taps.
Fuel and weight planning
Plan fuel burn and reserves, then check weight and balance against your aircraft profile before you taxi.
One-tap notes
One button to start taking notes — capture a clearance, fuel slip, or reminder without leaving the calculator.
Works offline
Every calculation runs on device. No account, no network connection, and no waiting on a signal in the run-up area.
Built for the cockpit
Large tap targets, high-contrast typography, and a night-friendly theme that will not wreck your dark adaptation.
Planning aid only. AviCalc is not certified avionics and is not a substitute for your aircraft’s approved flight manual, current charts and data, or certified equipment. Always verify results independently, and follow the regulations that apply to your operation. The pilot in command remains responsible for the safe conduct of every flight.
