Once the
flight is underway,
ground
speed checks
will
provide
a
more
accurate
basis for
estimating the
time enroute
and the corres-
ponding
fuel required
to complete
the
trip with
ample reserve.
LANDING
A
procedure
similar to
takeoff
should be used
for
estimating
the
landing
distance
at
the destination airport. Figure
5-10
presents
land-
ing
distance
information for
the short field technique.
The distances
corresponding
to 2000 feet and 30oC are as follows:
Ground roll 590
Feet
Total
distance to clear a 5O-foot obstacle 1370
Feet
A correction for
the effect of
wind
may
be made
based on
Note
2 of the
landing
chart using
the same
procedure
as
outlined for takeoff.
