VFR day and night 2. IFR day and night REQUIRED EQUIPMENT FOR VARIOUS CONDITIONS OF FLIGHT Federal Aviation Regulations (91.3(a), 91.24, 91.25, 91.32, 91.33,91.52,91.90,91.97, 91.170) specify the minimum numbers and types of airplane instruments and equipment which must be installed and operable for various kinds of flight conditions. This includes VFR day, VFR night, IFR day, and IFR night. February 1979 2-9 Section II Limitations BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Regulations also require that all airplanes be certificated by the manufacturer for operations under various flight conditions. At certification, all required equipment must be in operating condition and should be maintained to assure continued airworthiness. If deviations from the installed equipment were not permitted, or if the operating rules did not provide for various flight conditions, the airplane could not be flown unless all equipment was operable. With appropriate limitations, the operation of every system or component installed in the airplane is not necessary, when the remaining operative instruments and equipment provide for continued safe operation. Operation in accordance with limitations established to maintain airworthiness, can permit continued or uninterrupted operation of the airplane temporarily. For the sake of brevity, the Required Equipment Listing does not include obviously required items such as wings, rudders, flaps, engine, landing gear, etc. Also the list does not include items which do not affect the airworthiness of the airplane such as entertainment systems, passenger convenience items, etc. However, it is important to note that ALL ITEMS WHICH ARE RELATED TO THE AIR- WORTHINESS OF THE AIRPLANE AND NOT INCLUDED ON THE LIST ARE AUTOMATICALLY REQUIRED TO BE OPERATIVE. To enabJe the pilot to rapidly determine the FAA equipment requirements necessary for a flight into specific conditions, the following equipment requirements and exceptions are presented. It is the final responsibility of the pilot to determine whether the lack of, or inoperative status of a piece of equipment on his airplane, will limit the conditions under which he may operate the airplane. 2-10 February 1 979 BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Section II Limitations WARNING FLIGHT IN ICING CONDITIONS PROHIBITED.

Speed builds up rapidly in a spiral dive, requiring high pullout loads; therefore, if a spiral is inadvertently entered recovery from the spiral is to be ini- itiated within two turns. ENTRY: Stall the airplane with the control column hard back, throttle in idle position, flaps up, carburetor heat as required and with the nose about 15° above the horizon. At the stall, apply full rudder in the direction required to spin. A slight rudder application immediately before the stall will assure the dir~~tion of spin. The airplane nose will drop and rotate towards applieBrlJ(;Jder. When the wings are 90° to the horizon, apply full aileron ~g~jr1St -O.e. against the intended direction of spin). The airplane will go.slightly inv~rted and enter a normal spin. If aileron agai!'st is not ap.p,!ied or applied too lateLthe airplane will enter a spiral dive, and recovery must be initiatea by the second turn. If the full back stick is not applied and held, the airplane may spiral. Again recovery must be initiated not later than the second turn. If the aileron is applied too early, the airplane will not rotate and merely remain in a straight stalled condition. RECOVERY: Immediately move the control col- umn full forward and simultaneously apply full rudder opposite to the direction of the spin; continue to hold this control position until rota- tion stops and then neutralize all controls and execute a smooth pullout. Ailerons should be neutral and throttle in idle position at all times during recovery."
