other than at hardstands. Aprons are classified as
service, warm-up, and parking.
END ZONE. A cleared and graded area that extends
beyond each end of the runway. The dimensions of the
end zone depend upon the safety clearances specified
by the design criteria for advanced-base airfields. (See
fig. 3-15.)
GLIDE ANGLE. The angle between the flight path
of an airplane during a glide for landing or takeoff and
a horizontal plane fixed relative to the runway. The glide
angle is measured from the outer edge of the end zone.
(See fig. 3-15.)
HARDSTAND. A stabilized, paved, or metal-
plank-surfaced parking area of sufficient size and
strenght tp accomodate a limited number of aircraft.
Handstands are usually dispersed over the ground area
beyond the safety clearance zones of a landing strip.
They provide protection for aircraft on the field by
dispersal, concealment, and revetment
LANDING AREA. The paved portion, or runaway,
of the landing field. The landing area should have
unobstructed approaches and should be suitable for the
safe landing and takeoff of aircraft under ordinary
weather conditions.
