Distance/Time Planning

RBERNARD

Hello
When I use the planning tool the time of the planning is not directly linked to the speed and the distance.
For example : distance 206 Nm, Speed 5 knts time of the passage 37 hours (1 day and 13 hours) but it should be (to my calculation) 41 or 42 hours (206/5 = 41,66).
Do you have an explanation?

@RBERNARD
It’s a bit strange. I get the correct time duration (24h + 18h = 42h).
Have you set the correct units, NM and kt ?
