Tempera-ture Pressure Pressure Altitude is the altitude read from an altimeter Altitude 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-throttle RPM engine runup when the airplane is on the ground and stationary. AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY Never Exceed Speed is the speed limit that may not be exceeded at any time. Stalling Speed or the minimum steady flight speed at which the airplane is controllable. Stalling Speed or the minimum steady flight speed at which the airplane is controllable in the landing configu¬ration at the most forward center of gravity. Demon¬strated Crosswind Velocity Usable Fuel Unusable Fuel Demonstrated Crosswind Velocity is the velocity of the crosswind component for which adequate control of the airplane during takeoff and landing was actually demon¬strated during certification tests. The value shown is not considered to be limiting. Usable Fuel is the fuel available for flight planning. Unusable Fuel is the quantity of fuel that can not be safely used in flight.
