Flight Duration Estimate
Estimate flight time from distance and average ground speed.
About Flight Duration Estimate
Dividing the flight distance by the cruise speed gives the airborne time, to which ground taxiing is added for a door-to-door figure. This frames the real block time for scheduling. Actual travel time includes taxi, not just air time, so a full estimate prevents over-planning tight connections at either end.
Formula
Flight Duration Estimate
Air time = distance / speed; total = air time + taxi/60
- taxi
- Time taxiing to and from the runway
Worked example
With the default values below, Flight Duration Estimate returns Air Time of 6.24. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Flight Duration Estimate calculated?
Air time = distance / speed; total = air time + taxi/60 Dividing the flight distance by the cruise speed gives the airborne time, to which ground taxiing is added for a door-to-door figure. This frames the real block time for scheduling.
Why does Flight Duration Estimate matter?
Actual travel time includes taxi, not just air time, so a full estimate prevents over-planning tight connections at either end.
What values do I need to enter?
This calculator takes 3 inputs: Flight distance, Cruise speed, Ground taxi time. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
