### Flight duration calculation

Posté:

**Ven Jan 18, 2019 11:27**Hello mates,

I'm trying to calculate my next routes for maximum use for my planes. I want to buy cargoplanes for over 200 routes and I want to get the discount.

But I have some problems with the flightduration.

I have these examples:

A310-300F (max 850 km/h)

GRZ-VIE 150km - flight duration is 2h30 (mean an average of 60 km/h)

GRZ-DRS 476km - flight duration is 3h15 (mean an average of 146 km/h)

VIE-SVO 1663km - flight duration is 6h00 (mean an average of 277 km/h)

Saab S-340BF (max 467 km/h)

GRZ-VIE 150km - flight duration is 2h45 (mean an average of 55 km/h)

GRZ-DRS 476km - flight duration is 4h15 (mean an average of 112 km/h)

VIE-SVO 1663km - flight duration is 9h15 (mean an average of 181 km/h)

I don't find a logical way to calculate these duration.

Maybe the way from start to max speed (f.e. 0 to 850km/h in 30 minutes) and the same for landing or/and some minutes for grounding...

Maybe you have any ideas.
