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 253 nautical miles
(2) Cruise Distance
(e)(l) minus (c)(4) minus
(d)(2), (253 nautical
miles minus 10.3 nautical
miles minus 26 nautical
miles)
(3) Cruise Power
(4) Cruise Speed
(5) Cruise Fuel
Consumption
(6) Cruise Time
(e)(2) divided by (e)(4),
(217 nautical miles
divided by 154 KTS)
(7) Cruise Fuel
(e)(5) multiplied by (e)(6),
(16.5 GPH multiplied
by 1.41 hrs.)

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:
(1)
Total Flight Time
(c)(3) plus (d)(l) plus (e)(6),
(.10 hrs. plus .18 hrs. plus 1.41 hrs.) 1.69 hr.
(6 min. plus II min. plus I hr.
24 min.) 1 hr. 41 min.
