Whenever possible, they have been categorized for ready reference. GENERAL AIRSPEED TERMINOLOGY AND SYMBOLS CAS Calibrated Airspeed is the indicated speed of an airplane, corrected for position and instrument error. Calibrated airspeed is equal to true airspeed in standard atmosphere at sea level. GS Ground Speed is the speed of an airplane relative to the ground. lAS Indicated Airspeed is the speed of an airplane as shown on the airspeed indicator when corrected for instrument error. lAS values published in this handbook assume zero instrument error. KCAS Calibrated Airspeed expressed in "knots", KIAS Indicated Airspeed expressed in "knots". TAS True Airspeed is the airspeed of an airplane relative to undisturbed air which is the CAS corrected for altitude, temperature, and compressibility. 1-1 2 February 1979 BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Section I General VA Maneuvering Speed is the maximum speed at which application of full available aero- dynamic control will not overstress the airplane. VFE Maximum Flap Extended Speed is the highest speed permissible with wing flaps in a pre- scribed extended position. VNE Never Exceed Speed is the speed limit that may not be exceeded at any time. VNO Maximum Structural Cruising Speed is the or Vc speed that should not be exceeded except in smooth air and then only with caution. Vs Stalling Speed or the minimum steady flight speed at which the airplane is controllable. VSO Stalling Speed or the minimum steady flight speed at which the airplane is controllable in the landing configuration. Vx Best Angle-of-Climb Speed is the airspeed which delivers the greatest gain of altitude in the shortest possible horizontal distance. Vy Best Rate-of-Climb Speed is the airspeed which delivers the greatest gain in altitude in the shortest possible time. Cruise Recommended Climb Speed for enroute climb. Climb February 1979 1-13 Section I General BEECHCRAFT Sundowner 180 C23 (M-1285 and After) METEOROLOGICAL TERMINOLOGY ISA OAT Indicated Pressure Altitude Pressure Altitude 1-14 I nternational 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 indica- tions 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 Graph. February 1979 BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Section I General Station Pressure Wind 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. POWER TERMINOLOGY Take off and Maximum Continuous Highest power rating not limited by time. ENGINE CONTROLS AND INSTRUMENTS Throttle Control Mixture Control EGT (Exhaust Gas Temperature) Indicator Tachometer August, 1980 Used to control power by i ntro- ducing fuel-air mixture into the intake passages of the engine. This control is used to set fuel flow in all modes of operation and cuts off fuel completely for engine shut down. This indicator is used to identify the lean and best power fuel flow for various power settings during cruise. Indicates the rpm of the engine/ propeller. 1·15 Section I General BEECHCRAFT Sundowner 180 C23 (M-1285 and After) AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY Climb Gradient Demonstrated Crosswind Velocity MEA Route Segment GPH PPH 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 value shown is considered to be limiting. Minimum enroute IFR altitude. 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. Pounds per hour. WEIGHT AND BALANCE TERMINOLOGY Reference Datum Station 1-16 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. February 1979 BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Section I General Arm Moment Airplane Center of Gravity (C.G.) C.G. Arm C.G. Limits Usable Fuel Unusable Fuel Standard Empty Weight Basic Empty Weight February 1979 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. Fuel available for flight planning. Fuel remaining after a runout test has been completed in accordance with governmental regulations. Weight of a standard airplane including unusable fuel, full operating fluids and full oil. Standard empty weight plus optional equipment. 1-17 Section I General Payload Useful Load Maximum Ramp Weight Maximum Take-off Weight Maximum Landing Weight Zero Fuel Weight Tare Leveling Points Jack Points 1-18 BEECHCRAFT Sundowner 180 C23 (M-1285 and After) Weight of occupants, cargo and baggage. Difference between take-off weight, or ramp weight if applicable, and basic empty weight. Maximum weight approved for ground maneuvering. (It includes weight of start, taxi, and run-up fuel). Maximum weight approved for the start of the take-off run. Maximum weight approved for the landing touchdown. Weight exclusive of usable fuel. The weight of chocks, blocks, stands, etc., used on the scales when weighing an airplane. Those points which are used during the weighing process to level the airplane.
