Climb optimisation
Just a question i've been trying to look at but am dumbfounded if I can find an answer.
On climb, strong jet streams at upper levels.
On climb is it better to,
1. maintain the FMS calulated climb speed (284/.77 kts for example) or
2. BRoC (somewhere between 250 and 275 into .76 until up there) if strong tailwinds at upper levels, and/or
3. in the case of strong headwinds at upper levels maintain FMS climb to around FL200 then accelerate to 300-320/.78.
Cheers
