PART V-OPERATING DATA
96. Flight planning data
(a) The tables on the following pages show the flight plan-
ning data for:-
(i) Climbing
The climb tables give the data for climbs in I.S.A.
conditions using the speeds recommended in para.
64. (Repeated in Col. 1 of the tables.) The cruise
data tables are based on rehear take-offs followed
by non-reheat climbs. (Reheat climb data is given
on page 92.)
(ii) Cruising
Each separate altitude block in the cruise table
shows:-
(1) The speed for maximum range, the approximate
A.N.M./I00 lb. and the approximate fuel consump-
tion 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
let-down, 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. 64 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 tables give the data for descending from
one height to another.
(b) Use of the tables
(i) Pre-flight planning
Enter the cruise data table in the sea level block at
the fuel state applying immediately after take-off. 86
