Revision 7 1-7 SECTION 1 CESSNA GENERAL MODEL 172R SYMBOLS, ABBREVIATIONS AND TERMINOLOGY GENERAL AIRSPEED TERMINOLOGY AND SYMBOLS KCAS Knots Calibrated Airspeed is indicated airspeed corrected for position and instrument error and expressed in knots. Knots calibrated airspeed is equal to KTAS in standard atmosphere at sea level. KIAS Knots Indicated Airspeed is the speed shown on the airspeed indicator and expressed in knots. KTAS Knots True Airspeed is the airspeed expressed in knots relative to undisturbed air which is KCAS corrected for altitude and temperature. V A Maneuvering Speed is the maximum speed at which full or abrupt control movements may be used without overstressing the airframe. V FE Maximum Flap Extended Speed is the highest speed permissible with wing flaps in a prescribed extended position. V NO Maximum Structural Cruising Speed is the speed that should not be exceeded except in smooth air, then only with caution. V NE Never Exceed Speed is the speed limit that may not be exceeded at any time. V S Stalling Speed or the minimum steady flight speed is the minimum speed at which the airplane is controllable. V SO Stalling Speed or the minimum steady flight speed is the minimum speed at which the airplane is controllable in the landing configuration at the most forward center of gravity. V X Best Angle-of-Climb Speed is the speed which results in the greatest gain of altitude in a given horizontal distance. V Y Best Rate-of-Climb Speed is the speed which results in the greatest gain in altitude in a given time. 1-8 Original Issue CESSNA SECTION 1 MODEL 172R GENERAL METEOROLOGICAL TERMINOLOGY OAT Outside Air Temperature is the free air static temperature. It may be expressed in either degrees Celsius or degrees Fahrenheit. Standard Standard Temperature is 15°C at sea level Temperature pressure altitude and decreases by 2°C for each 1000 feet of altitude. Pressure Pressure Altitude is the altitude read from an Altitude altimeter when the altimeter's barometric scale has been set to 29.92 inches of mercury (1013 mb). ENGINE POWER TERMINOLOGY BHP Brake Horsepower is the power developed by the engine. RPM Revolutions Per Minute is engine speed. Static Static RPM is engine speed attained during a full RPM throttle engine runup when the airplane is on the ground and stationary. MAP Manifold Absolute Pressure is the absolute pressure measured in the engine induction system. MAP is measured in units of inches of mercury (inHG). Lean Decreased proportion of fuel in the fuel-air mixture Mixture supplied to the engine. As air density decreases, the amount of fuel required by the engine decreases for a given throttle setting. Adjusting the fuel-air mixture to provide a smaller portion of fuel is known as "leaning" the mixture. Rich Increased proportion of fuel in the fuel-air mixture Mixture supplied to the engine. As air density increases, the amount of fuel required by the engine increases for a given throttle setting. Adjusting the fuel-air mixture to provide a greater portion of fuel is known as "richening" the mixture. Full Rich Mixture control full forward (pushed in, full control travel, toward the panel). Idle Cutoff Mixture control full aft (pulled out, full control travel, toward the panel). Revision 7 1-9 SECTION 1 CESSNA GENERAL MODEL 172R ENGINE POWER TERMINOLOGY (Continued) Full Throttle full forward (pushed in, full control travel, Throttle toward the panel) Also known as "full open" throttle. Closed Throttle full aft (pulled out, full control travel, away Throttle from the panel). Also known as the throttle "idle" position. AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY Demon- Demonstrated Crosswind Velocity is the velocity strated of the crosswind component for which adequate Crosswind control of the airplane during takeoff and landing Velocity was actually demonstrated during certification tests. The value shown is not considered to be limiting. Usable Fuel Usable Fuel is the fuel available for flight planning. Unusable Unusable Fuel is the quantity of fuel that can not be Fuel safely used in flight. GPH Gallons Per Hour is the amount of fuel consumed per hour. NMPG Nautical Miles Per Gallon is the distance which can be expected per gallon of fuel consumed at a specific engine power setting and/or flight configuration. g g is acceleration due to gravity. Course Course Datum is the compass reference used by Datum the autopilot, along with course deviation, to provide lateral control when tracking a navigation signal. I1-10 Revision 7 CESSNA SECTION 1 MODEL 172R GENERAL WEIGHT AND BALANCE TERMINOLOGY Reference Reference Datum is an imaginary vertical plane from Datum which all horizontal distances are measured for balance purposes. Station Station is a location along the airplane fuselage given in terms of the distance from the reference datum. Arm Arm is the horizontal distance from the reference datum to the center of gravity (C.G.) of an item. Moment Moment is the product of the weight of an item multiplied by its arm. (Moment divided by the constant 1000 is used in this handbook to simplify balance calculations by reducing the number of digits.) Center of Center of Gravity is the point at which an airplane, or Gravity equipment, would balance if suspended. Its distance (C.G.) from the reference datum is found by dividing the total moment by the total weight of the airplane. Revision 7 1-11I SECTION 1 CESSNA GENERAL MODEL 172R WEIGHT AND BALANCE TERMINOLOGY (Continued) C.G. Center of Gravity Arm is the arm obtained by Arm adding the airplane's individual moments and dividing the sum by the total weight. C.G. Center of Gravity Limits are the extreme center of Limits gravity locations within which the airplane must be operated at a given weight. Standard Standard Empty Weight is the weight of a standard Empty airplane, including unusable fuel, full operating fluids Weight and full engine oil. Basic Empty Basic Empty Weight is the standard empty weight Weight plus the weight of optional equipment. Useful Load Useful Load is the difference between ramp weight and the basic empty weight. MAC MAC (Mean Aerodynamic Chord) is the chord of an imaginary rectangular airfoil having the same pitching moments throughout the flight range as that of the actual wing. Maximum Maximum Ramp Weight is the maximum weight Ramp approved for ground maneuver, and includes the Weight weight of fuel used for start, taxi and runup. Maximum Maximum Takeoff Weight is the maximum weight Takeoff approved for the start of the takeoff roll. Weight Maximum Maximum Landing Weight is the maximum weight Landing approved for the landing touchdown. Weight Tare Tare is the weight of chocks, blocks, stands, etc. used when weighing an airplane, and is included in the scale readings. Tare is deducted from the scale reading to obtain the actual (net) airplane weight.

Aerobatics that may impose high loads should not be attempted. The important thing to bear in mind in flight maneuvers is that the airplane is clean in aerodynamic design and will build up speed quickly with the nose down. Proper speed control is an essential re- quirement for execution of any maneuver, and care should always be exercised to avoid excessive speed which in turn can impose ex- cessive loads. In the execution of all maneuvers, avoid abrupt use of controls.
