NOTE
The remainder
of
the perfbrmance charts
used
in
this flight
plan
example
assume
no wind condition. The
effect
of winds aloft
must
be
considered by the pilot
when computing climb, cruise a,d
descent
performance.
(c)
Climb
The next step
in flight planning
is to determine the
necessary
climb
segment components.
The desired cruise pressure altitude
anc-l
corresponding cruise outsicle air temperature
values
are the
first
variables
to
be considered
in
determining tfre climb components fiorn
the Tirne,
Distance, and Fuel
to (llirnb
graph (Figure 5-13).
After
the tinre, distanie and fuel for
the cruise
Pressure
altitude and outside air
temperature values have been established, apply
the
existing
conditions at the departure field to graph (Figure 5-13) Now, subtract the valuei obtained
froi
the graph
for the field of departure c6nditions from
those
for the
cruise pressure altitude.
The remaining values are the true fuel, distance and time contponents
for the climb
segment
of the
flight
plan corrected for field pressure altitude and tenrperature.
The following values
