About this app

Flight Folder Calculator is the flight computer of the Flight Folder suite. It works offline, keeps your units and aircraft limits, and passes values between tools so you type them once.

Weather: density and pressure altitude, cloud base and freezing level, hydroplaning speed, crosswind and headwind against your aircraft's limits.
Planning: true airspeed and Mach, heading and ground speed, compass heading, flight time, fuel (required, endurance, burn rate, range), MAC and rate of climb.
Navigation: actual ground speed, wind finder and great-circle distance.
IFR: ICAO cold temperature corrections, flight path angle tables, metric flight levels for China and Russia, and live GPS bearing and distance to airports and navaids.
Converters: temperature, fuel by type, pressure, length, rate, weight and 58 currencies.
Reference: ICAO, FAA and EASA abbreviations, NOTAM and METAR/TAF codes, aircraft and airport terms.

Also: a Math / Time calculator from every screen, a scratchpad, favourites and history, a Favourites home-screen widget, light and dark themes.

Six calculators, three converters and the Reference library work without an account. A free Flight Folder account, the same one FF Logbook, FF Checklist and FF Dispatch use, opens every tool.

For situational awareness and training. Always use approved data and your aircraft's documents for flight.
