The distance required to accelerate an airplane
to a specified speed and, assuming failure of
an engine at the instant that speed is attained,
to bring the airplane to a stop.
The demonstrated ratio of the change in
height during a portion of a climb, to the
horizontal distance traversed in the same time
interval.
The demonstrated crosswind velocity is the
velocity of the crosswind component for
which adequate control of the airplane
during takeoff and landing was actually
demonstrated during certification tests.
A part of a route. Each end of that part is
identified by: ( I) a geographical local.ion; or
(2) a point at which a definite radio fix can
be established.
The horizontal distance from the reference
datum to the center of gravity (C.G .) of an
item.
The point at which an airplane would
balance if suspended. Its distance from the
reference datum is found by dividing the total
moment by the t0tal weight of the airplane.
The arm obtained by adding lhe airplane's
individual moments and dividing the sum by
the total weight.
The extreme center of gravity locations
within which the airplane must be operated at
a given weight.
