E6B Flight Computer +

Solve the wind triangle, crosswind, density altitude, true airspeed and fuel burn in seconds. Works fully offline in the cockpit, no account needed.

▶ Every calculation a student pilot needs for the written and check ride, in one clean tool. Solve the wind triangle for groundspeed and wind correction angle, then read heading and time straight off the result.

▶ Break wind into headwind and crosswind components against any runway. Pick the runway on a heading dial and see the numbers update as you turn.

▶ Enter pressure altitude and outside air temperature to get density altitude and corrected true airspeed. A live card reads your phone's barometer so you can check field conditions on the spot.

▶ Work fuel, time and distance three ways: burn rate and load to endurance, leg time, or required fuel. Convert knots, mph, km/h, nautical and statute miles, gallons, litres, feet, metres, inHg and hPa.

▶ Save your recent calculations and reuse them. Everything runs offline, so it works at altitude with no signal.

This app is a training and reference aid. Always confirm flight planning with official charts, your aircraft documents and current data before you fly.
