Vectr: E6B Flight Computer

Your E6B, solved. Vectr is a flight computer for student and private pilots, with big, clear numbers for the calculations you do in the cockpit, on the checkride and when you plan a flight.

Enter your course and the wind, and read the wind correction angle, true heading and ground speed at once.

No account is needed, and the calculators work offline.

• Wind triangle: wind correction angle, true heading and ground speed, plus a find-wind mode
• Headwind and crosswind components for any runway, with gusts
• Pressure altitude and density altitude, TAS from CAS, cloud base
• Time, speed and distance, fuel, descent and top of descent
• Unit converter for knots, feet, nautical miles, gallons, hPa, inHg and more
• Large, readable numbers in light and dark themes
• Works without an internet connection

What is free: all the calculators above. What is Pro: weight and balance with saved aircraft profiles and a CG envelope check, a METAR and TAF decoder that fills in the crosswind for you (it needs an internet connection), and saved aircraft and airports. Pro is optional and comes as a weekly or yearly subscription (the yearly plan starts with a 3-day free trial) or as a one-time lifetime purchase. The free version shows ads; Pro removes them.

Vectr collects anonymous usage statistics and crash reports to improve the app.

Vectr is a planning and training aid and is not meant for primary navigation. Always check your results against your aircraft's flight manual and official sources.
