hmmmm.
Denti...question...
Why can't you take off max thrust vs reduced...which seems less safe...
Do you set your reduced thrust to just make the balanced field requirements?
In GA we do max thrust...if we can't make balanced field, we change flaps, reduce fuel, find a longer runway, leave at a cooler time...ect...
It's pretty common though on a rediculously long runway I might not try to get that last 2% out of the engines and fiddle with the levers, just don't need it...
