CRUISE - FLIGHT LEVEL TABLE
The table below permits quick determination of the cruise flight level
for minimum fuel consumption, based on the trip distance and takeoff
weight. For each takeoff weight two different flight levels are calculated
(A or B) based on the following assumptions:
−
Condition (A): The flight level was calculated based only on
minimum fuel consumption. It may result on reduced time in leveled
flight for short trip distances.
−
Condition (B): The flight level was calculated based on a
combination of minimum fuel consumption and at least 40% of the
total flight time in cruise.
