747-400 step climb procedure
Hi everyone,
Did a quick search but could not find what I am looking for.
Difference btw OPT and MAX FMC computed altitudes can be as much as 4000 ft. What is the most efficient method to step cruise in the 744? Flying close to optimum (within 1000 ft)? Or right in the middle of the OPT and MAX FMC computed altitudes? Or even close to MAX?
Thank you in advance for any information!
