(a) Takeoff
(b) Cruise
For this the chart: fig.5-6 "Takeoff Distance (for short fields)" is to be used.
The values shown are based on the normal procedure "Takeoff - Short
Field“(see Section 4, “NORMAL PROCEDURES“).
By means of the appropriate column with the air temperature and the
linewithcorresponding altitude, the takeoffdistanceisfound.
Conservative values can be safely established by reading the chart at the
next higher value of altitude or temperature. This results in the
following:
GroundRoll 370 m(1214ft)
Totaldistancetoclear
a50-ftobstacle 475 m (1558 ft)
Therunway length of 2000 ft.is therefore sufficient.
The Chart figure then shows the existingwind conditions. The correction

The cruising altitude and the winds enroute are determined from route
restrictions and meteorological conditions. The optimal power setting
selection for cruise must be determined based on several factors. This
