SARATOGA PERFORMANCE
The cruise time
is
found by
dividing the
cruise distance by the
cruise speed
and
the
cruise
fuel is found by multiplying
the cruise
fuel
consumption
by the
cruise
time.
The
cruise calculations established
for the cruise
segment
of
the flight planning example are as follows:
(1)
Total Distance 223.5 nautical miles
(2)
Cruise Distance

Total Flight Time
The total flight
time is determined
by
adding
the time to climb,
the time to
descend
and the cruise time. Remember!
The time
values taken from the
climb and
descent graphs
are
in minutes and
must
be
converted to hours before adding
them to the cruise
time.
The following
flight time is required
for
the flight planning
example:
(
