But what you could do is to add an extra waypoint at the end of your bottom time (with a duration of 1 minute, say) and in the waypoint enter a 0 in the set point column. This signifies bailout to OC. That should turn on the gas calculation for the ascent including minimum gas.

I tried it but minimum gas calculation is not triggered.

Thanks Robert
