Engine Power Terminology 發(fā)動(dòng)機(jī)功率術(shù)語
HP Horsepower is the power developed by the engine.
MCP Maximum Continuous Power is the maximum power that can be used continuously.
MAP Manifold Pressure is the pressure measured in the engine’s induction system expressed as in. Hg. RPM Revolutions Per Minute is engine rotational speed.
• Static RPM is RPM attained during a full-throttle engine runup when the airplane is on the ground and stationary.

Performance and Flight Planning Terminology 性能和飛行計(jì)劃術(shù)語
g One “g” is a quantity of acceleration equal to that of earth’s gravity.
• Demonstrated Crosswind Velocity is the velocity of the crosswind component for which adequate control of the airplane during taxi, takeoff, and landing was actually demonstrated during certification testing. Demonstrated crosswind is not considered to be limiting.
• Service Ceiling is the maximum altitude at which the aircraft at maximum weight has the capability of climbing at a rate of 100 feet per minute.
GPH Gallons Per Hour is the amount of fuel (in gallons) consumed by the aircraft per hour.

NMPG Nautical Miles Per Gallon is the distance (in nautical miles) which can be expected per gallon of fuel consumed at a specific engine power setting and/or flight configuration.
• Unusable Fuel is the quantity of fuel that cannot be safely used in flight.
• Usable Fuel is the fuel available for flight planning.

Weight and Balance Terminology 載重平衡術(shù)語
c.g. Center of Gravity is 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.
• Arm is the horizontal distance from the reference datum to the center of gravity (c.g.) of an item. The airplane’s arm is obtained by adding the airplane’s individual moments and dividing the sum by the total weight.
