The formula
time = distance ÷ cruising speed + allowance
Use the great circle distance if you have the coordinates. Real routes are a little longer.
What to watch out for
The allowance covers the time on the ground and the slower parts of the flight. Propeller aircraft need a much lower cruising speed.
Frequently Asked Questions
How long is a 5,570 km flight?
About 7 h 3 min at 850 km/h with a 30-minute allowance.
Why does the return flight take a different time?
Winds at cruising height can blow at well over 100 km/h. Flying with them shortens the trip and flying against them lengthens it.
