将下列段落翻译成汉语：There are some problems caused by overloading an aircraft. The aircraft will need a higher takeoff speed, which results in a longer takeoff run. Both the rate and angle of climb will be reduced, the service ceiling will be lowered. The cruising speed will be reduced, the cruising range shortened and maneuverability decreased. A longer landing roll will be required because the landing speed will be higher. Excessive loads will be imposed on the structure, especially the landing gear.
将下列段落翻译成汉语：The lift produced by a wing is determined by its airfoil shape, angle of attack, speed through the air, and the air density. When an aircraft takes off from an airport with a high density altitude, it must accelerate to a speed faster than would be required at sea level to produce enough lift to allow takeoff; therefore, a longer takeoff run is necessary. The distance needed may be longer than the available runway. When operating from a high-density altitude airport, the Pilot Operating Handbook (POH) or Airplane Flight Manual (AFM) must be consulted to determine the maximum weight allowed for the aircraft under the conditions of altitude, temperature, wind, and runway conditions.
将下列段落翻译成汉语：There are many factors that lead to efficient and safe operation of aircraft. Among these vital factors is proper weight and balance control. The weight and balance system commonly employed among aircraft consists of three equally important elements: the weighing of the aircraft, the maintaining of the weight and balance records, and the proper loading of the aircraft. An inaccuracy in any one of these elements affects the purpose of the whole system. The final loading calculations will be meaningless if either the aircraft has been improperly weighed or the records contain an error.
