PART V  OPERATING DATA
107. Flight planning data
(a) The tables on the following pages show the flight
planning data for:
(i) Climbing
The climb table gives the data for climbs in I.S.A.
conditions using the speed recommended in para. 69
(repeated in the table).
(ii) Cruising
Each separate altitude block in the cruise table
shows:
(1) The speed for maximum range, the approximate
A.N.M./100 lb. and the approximate fuel
consumption for the particular height. In
addition a speed band is given, use of any speed
within which should not cause more than a 5%
reduction in range.
(2) The range obtainable for various amounts of
available fuel when flying at the best range
speed for the height. The range given is to the
point of letdown, allowance being made for the
descent fuel required.
(3) The range obtainable for various amounts of
available fuel including the distance covered on
the climb, if a climb is made to another altitude.
In this case the climb must be made at the speed
given in para. 69 and the flight continued at the
new altitude at the best range speed for that
height.
NOTE.The range at any altitude is independent
of temperature, but dependent on the
weight of fuel carried.
(iii) Descent
The descent table gives data for descending from
one height to another.
