Zkpjm You can quote me, it's on paper and I do follow it.
And in 150 mi at the higher speed you can be using the fuel you saved in that
5 hour flight. We used to fly at 78 but the new flight plans are coming near
75,76. The speed is selected by the computer depending on the time vs fuel cost for that trip as given in the flight plan.
And I have a question for the guys flying airplanes with greater sweepback (777)
Whats the cruising Mack number at cost index zero?
