Best angle or best rate in departure?
Hi fellows,
Consider this case please:
Prior departure from an airport you receive this clearance from the ATC: "maintain runway heading until FL100 then turn left and proceed direct to XXXXX [to the first fix of route towards destination]".
The course to proceed to that fix is almost 180º of the runway heading, meaning while you fly keeping runway heading until FL100 you would be flying in the opposite direction to the destination.
There are no obstacles around the airport, and you want to use the less fuel for the trip.
What do think is the best course of action after cleaning the plane, to climb with best angle or with best rate of climb until reaching FL100 and turn to proceed to the destination?
Cheers!
