Flight Computer
The classic E6B a private pilot reaches for, now free and online. Works on any device, even offline.
The PilotMall E6B Flight Computer is a free online version of the classic E6B that private pilots use for VFR flight planning. Run it in any browser on your phone, tablet, or laptop, with no app to install and no sign in. It performs the same core calculations as a handheld electronic E6B, from density altitude and true airspeed to the wind triangle, weight and balance, and unit conversions.
What this flight computer calculates
- Density altitude and pressure altitude
- True airspeed (TAS)
- True altitude (cold-temperature correction)
- Wind correction angle, heading, and ground speed
- Winds aloft from heading and track
- Crosswind and headwind components
- Time, speed, and distance with ETA
- True, magnetic, and compass heading
- Required rate of climb
- Top of descent
- Glide range
- Fuel burn, endurance, and fuel weight
- Weight and balance with CG limits
- Cloud base and standard (ISA) temperature
- Unit conversions (distance, speed, volume, fuel, weight, pressure, temperature, time)
Frequently asked questions
Is the PilotMall E6B flight computer free?
Yes. It is completely free to use, with no account and no download. It runs in any modern web browser on a phone, tablet, or computer.
Does it work offline?
Once the page has finished loading, the calculations run entirely in your browser, so they keep working even if you lose your connection, for example in a run-up area or a hangar with no wifi.
How accurate is it?
It uses the International Standard Atmosphere and the standard E6B methods, and its results match dedicated handheld flight computers. It is intended for flight planning and training. Always cross-check your approved aircraft data, current weather, and official charts. It is not an approved source of performance data.
What can it calculate?
Density altitude, true airspeed, true altitude, the full wind triangle, crosswind components, time, speed, and distance, headings, climb and descent, glide range, fuel and endurance, weight and balance, cloud base, and unit conversions.
Do I still need a physical E6B for my checkride?
Usually yes. Many knowledge tests and practical exams expect a manual E6B or an approved electronic flight computer, and some testing centers do not allow phones. A dedicated E6B is also more durable in the cockpit.
Which flight computer should I buy?
For training and checkrides, a manual E6B is the standard choice. For fast, button-driven answers, an electronic flight computer is popular, and a rotating plotter pairs well for chart work. Browse the current lineup below.
