Beechcraft 55 Baron Pilot's Operating Handbook

engine is suddenly rendered inoperative. In- tentional failing of one engine below this speed is not recommended. Maneuvering Speed is the maximum speed at which application of full available aero- dynamic control will not overstress the airplane. Design flap speed is the highest speed permissible at which wing flaps may be actuated. Maximum Flap Extended Speed is the highest speed permissible with wing flaps in a pre- scribed extended position. 1-12 March 1979 March 1979 1-13 Section I General VLE VLO VNE VNO or VC BEECHCRAFT Baron E55 TE-938, TE-943 thru TE-1083 Maximum Landing Gear Extended Speed is the maximum speed at which an airplane can be safely flown with the landing gear extended. Maximum Landing Gear Operating Speed is the maximum speed at which the landing gear can be safely extended or retracted. Never Exceed Speed is the speed limit that may not be exceeded at any time. Maximum Structural Cruising Speed is the speed that should not be exceeded except in smooth air and then only with caution. Stalling Speed or the minimum steady flight speed at which the airplane is controllable. VS VSO Stalling Speed or the minimum steady flight speed at which the airplane is controllable in the landing configuration. VX VY Best Angle-of-Climb Speed is the airspeed which delivers the greatest gain of altitude in the shortest possible horizontal distance. Best Rate-of-Climb Speed is the airspeed which delivers the greatest gain in altitude in the shortest possible time. BEECHCRAFT Baron E55 TE-938, TE-943 thru TE-1083 METEOROLOGICAL TERMINOLOGY ISA OAT Indicated Pressure Altitude Pressure Altitude Section I General International Standard Atmosphere in which (1) The air is a dry perfect gas; (2) The temperature at sea level is 15° Celsius (59° Fahrenheit); (3) The pressure at sea level is 29.92 in. Hg (1013.2 millibars); (4) The temperature gradient from sea level to the altitude at which the temperature is -56.5° C (-69.7° F) is -0.00198° C (-0.003566° F) per foot and zero above that altitude. Outside Air Temperature is the free air static temperature, obtained either from inflight temperature indications adjusted for instrument error and compressibility effects, or ground meteorological sources. The number actually read from an altimeter when the barometric sub- scale has been set to 29.92 in. Hg (1013.2 millibars). Altitude measured from standard sea-level pressure (29.92 in. Hg) by a pressure or barometric altimeter. It is the indicated pressure altitude corrected for position and instrument error. In this Handbook, altimeter instrument errors are assumed to be zero. Position errors may be obtained from the Altimeter Correction Chart. 1-14 March 1979 March 1979 1-15 Section I General Station Pressure Wind BEECHCRAFT Baron E55 TE-938, TE-943 thru TE-1083 Actual atmospheric pressure at field elevation. The wind velocities recorded as variables on the charts of this hand- book are to be understood as the head- wind or tailwind components of the reported winds. BEECHCRAFT Baron E55 E-938, TE-943 thru TE-1083 ENGINE CONTROLS AND INSTRUMENTS TERMINOLOGY *hrottle Control Section I General The lever used to control the introduc- tion of a fuel-air mixture into the intake passages of an engine. 'ropeller Control POWER TERMINOLOGY Take-off and Maximum The highest power rating not limited by time. Mixture Control Continuous Cruise Climb Power recommended for cruise climb. 'ropeller Governors Maximum Cruise The highest power settings recom- mended for cruise. Manifold Pressure Gage Recommended Intermediate power settings Cruise for which cruise power settings are presented. This lever requests the governor to maintain rpm at a selected value and, in the maximum decrease rpm position, feathers the propellers. This lever, in the idle cut-off position, stops the flow of fuel at the injectors and in the intermediate thru the full rich positions, regulates the fuel air mixture. The governors maintain the selected rpm requested by the propeller control levers. An instrument that measures the ab- solute pressure in the intake manifold of an engine, expressed in inches of mercury (in. Hg). Tachometer An instrument that indicates the ro- tational speed of the propeller (and en- gine) in revolutions per minute (rpm). 1-17 Economy Cruise 1-16 The lowest power setting for which cruise power settings are presented. March 1979 March 1979 Section I General BEECHCRAFT Baron E5 TE-938, TE-943 thru TE-108 AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY Climb Gradient Demonstrated Crosswind Velocity Accelerate- Stop Distance Accelerate- Go Distance The 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 com- ponent for which adequate control of the airplane during take-off and land- ing was actually demonstrated during certification tests. The distance required to accelerate 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 distance required to accelerate to a specified speed and, assuming failure of an engine at the instant that speed is attained, feather inoperative propeller and continue takeoff on the remaining engine to a height of 50 feet Minimum enroute IFR altitude. MEA Route Segment A part of a route. Each end of that part is identified by: (1) a geograph- ical location; or (2) a point at which a definite radio fix can be established. U.S. Gallons per hour.

Limits Section I General An imaginary vertical plane from which all horizontal distances are measured for balance purposes. A location along the airplane fuselage usually given in terms of distance from the reference datum. The horizontal distance from the ref- erence datum to the center of gravity (C.G.) of an item. The product of the weight of an item multiplied by its arm. (Moment divided by a constant is used to simplify bal- ance calculations by reducing the number of digits.) 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 total weight of the airplane. The arm obtained by adding the air- plane's individual moments and dividing the sum by the total weight. The extreme center of gravity loca- tions within which the airplane must be operated at a given weight. Usable Fuel Fuel available for flight planning.

VFR day and night 2. IFR day and night 3. FAR 91 operations when all pertinent limitations and performance considerations are complied with. 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. 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 2-10 March 1979 BEECHCRAFT Baron E55 TE-938, TE-943 thru TE-1083 Section II Limitations 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 galley equipment, entertainment systems, passenger convenience items, etc. However, it is important to note that ALL ITEMS WHICH ARE RELATED TO THE AIRWORTHINESS OF THE AIRPLANE AND NOT INCLUDED ON THE LIST ARE AUTOMATICALLY REQUIRED TO BE OPERATIVE. To enable 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. WARNING FLIGHT IN KNOWN ICING CONDITIONS PROHIBITED. LEGEND (-) Indicates that the item may be inoperative for the specified condition.
