Aviation Calculators

Density altitude from field elevation, altimeter setting and temperature, exact and by rule of thumb, with a performance flag.

E6B arithmetic: give any two of distance, groundspeed and time for the third, plus fuel burn, reserve and range.

Glide distance, time and sink rate from altitude above ground, glide ratio and best-glide speed, with headwind or tailwind.

Standard atmosphere at an altitude: temperature, pressure, density, sound speed, and ISA deviation for a measured temperature.

Pressure altitude from field elevation and altimeter setting (inHg or hPa), exact ISA result and the 1000 ft per inHg rule.

True airspeed, Mach and equivalent airspeed from calibrated airspeed, pressure altitude and outside air temperature.

Turn rate, radius, bank angle and load factor from true airspeed, plus holding pattern leg length, width and time.

Headwind or tailwind and crosswind (left or right) from wind direction and speed against a runway number or heading, with gusts.

E6B wind triangle: wind correction angle, heading and groundspeed for a course, or track and groundspeed for a heading flown.
