MANEUVERING LIMITS
5.13 MANEUVERING LIMITS.
The AH-64A helicopter is subject to the maneuvering re-
strictions shown in figure 5-3. The term “empty” for exter-
nal fuel tank(s) is defined as no usable fuel remaining in
the tank.
a. Avoid large, abrupt pedal inputs in arresting right
hovering/low speed yawing turns greater than 60/sec.
This is to avoid excessive tail rotor drive system loads.
b. Intentional maneuvers beyond attitudes of 30 in
pitch or 60 in roll are prohibited.
c. Flight, hovering flight, and ground taxiing with the
canopy enclosure open is prohibited, except for smoke/
fume elimination.
d. With external fuel tanks (2 or 4) containing fuel
symmetrically installed, the following restrictions apply:
(1) Normal load factor of 2 g’s shall not be exceed-
ed.
(2) Maneuvers are limited to those required to
takeoff, climb to optimum altitude, heading/course correc-
tions, obstacle avoidance, descend, and land.
(3) Two hundred thirty (230) gallon external fuel
tanks shall be in the flight stowed position [four degrees
(4) nose–up with respect to waterline (WL)].
(4) Rapid and step–shaped pedal inputs in excess
of 1/2 inch shall be avoided. This is to avoid excessive
torquing of pylon structure.
5.14 LANDING LIMITS.
Do not complete a landing on terrain which produces a
pitch attitude change from a hover greater than 7 nose up
or 12 nose down; or a roll attitude greater than 10.
