Formula
Ref- Speed·Distance·Time: time = distance ÷ ground speed
- Fuel: trip fuel = time × burn, plus reserve
- Wind: solve the triangle for GS, drift and heading
Worked example
RefTime-Speed-Distance mode: 240 nm at 120 kt ground speed.
- 1.Pick the Speed / Distance / Time function.
- 2.Time = 240 ÷ 120 = 2.0 h = 2:00.
- 3.Switch modes for fuel, wind, or unit conversions.
2:00 en route — plus fuel, wind, and conversion modes.
How it works
RefA digital take on the E6B flight computer. Instead of a spinning wheel, pick a function — time-speed-distance, fuel, the wind triangle, or unit conversions — and only that function's inputs appear. Each mode reuses the same maths as the dedicated Flight Deck tool, so the answers match exactly.
DGCA student tip
ExamThe mechanical E6B does the same four things behind this tool. Master the relationships (distance = speed × time; fuel = burn × time; drift from the wind triangle) and the device — physical or digital — is just bookkeeping.
Common mistakes
Watch- Using TAS where ground speed belongs in time and fuel calculations.
- Forgetting to add the reserve on top of trip fuel.
- Converting between units of different quantities (e.g. speed to pressure).
