Title: "Optimum" flight levels?
Linear Mode
#1
A question regarding flight levels, especially on long flights. As I burn off fuel (in the LevelD 767 in this case), the FMC slowly raises the "Optimum Flight Level". My question...how much should I "chase" this? Obviously I need to wait for a 2,000 ft. increase so that I stay within the correct FL for my direction of flight but...is it worth stepping up 2,000 ft. when 2/3 of flight is done? My current flight (AAL039, 767-300, KSFO-PHNL) started at FL340 and I expect the "Optimum" to move to FL360 about 2/3 of the flight. Should I bother with a FL increase to FL360, at this point?

Thanks for any guidance.

Vic
