§3.778 Operating limitations—.

(a) Airspeed limitations. Sufficient information shall be included to permit proper marking of the airspeed limitations on the indicator as required in § 3.757. It shall also include the design, maneuvering speed, and the maximum safe air speed at which the landing gear can be safely lowered. In addition to the above information, the significance of the air speed limitations and of the color coding used shall be explained. (b) Power-plant limitations. Sufficient information shall be included to outline and explain all powerplant limitations (see § 3.744) and to permit marking the instruments as required in § 3.759. (c) Weight. The following information shall be included: (1) Maximum weight for which the airplane has been certificated, (2) Airplane empty weight and center of gravity location, (3) Useful load, (4) The composition of the useful load, including the total weight of fuel and oil with tanks full. (d) Load distribution. he center of gravity position within approved limits. (1) All authorized center of gravity limits shall be stated. If the available space for loading the airplane is adequately placarded or so arranged that any reasonable distribution of the useful load listed in weight above will not result in a center of gravity location outside of the stated limits, this section need not include any other information than the statement of center of gravity limits. (2) In all other cases this section shall also include adequate information to indicate satisfactory loading combinations which will assure maintaining the center of gravity position within approved limits. (e) Maneuvers. All authorized maneuvers and the appropriate air-speed limitations as well as all unauthorized maneuvers shall be included in accordance with the following: (1) Normal category. All acrobatic maneuvers, including spins, are unauthorized. If the airplane has been demonstrated to be characteristically incapable of spinning in accordance with § 3.124 (d), a statement to this effect shall be entered here. (2) Utility category. All authorized maneuvers demonstrated in the type flight tests shall be listed, together with recommended entry speeds. All other maneuvers are not approved. If the airplane has been demonstrated to be characteristically incapable of spinning in accordance with § 3.124 (d), a statement to this effect shall be entered here. (3) Acrobatic category. All approved flight maneuvers demonstrated in the type flight tests shall be included, together with recommended entry speeds. (f) Flight load factor. The positive limit load factors made good by the airplane’s structure shall be described here in terms of accelerations. (g) Flight crew. When a flight crew of more than one is required to operate the airplane safely, the number and functions of this minimum flight crew shall be included.
