Evaluates great-circle distance under average multi-engine commercial jet speed.

Airspeed Distance Math

Air hours = (Distance / 800 km/h) + 0.5 hours setup

Divides routes by 800 km/h (average jet cruising speed) and adds 30 minutes for takeoff and landing paths.

Example

A Rome to New York direct route span is modeled at approx 8.5 to 9 hours flight duration.

Note

Winds like jet streams can significantly expand or shorten flight times between east and west directions.
