副翼控制系統(tǒng)提供飛機(jī)縱向轉(zhuǎn)動(dòng)的方式。副翼控制系統(tǒng)通過(guò)轉(zhuǎn)動(dòng)機(jī)長(zhǎng)或副駕位的副翼控制輪作動(dòng)。自動(dòng)駕駛系統(tǒng)也可提供控制輸入。這些輸入控制驅(qū)動(dòng)副翼的液壓動(dòng)力系統(tǒng)。轉(zhuǎn)動(dòng)副翼離開配平位置,致使飛機(jī)轉(zhuǎn)動(dòng)并改變姿態(tài)?刂泼娼嵌鹊囊苿(dòng)形成“變化率”。當(dāng)姿態(tài)變化達(dá)到希望的量值時(shí),控制面再成流線型,作用在飛機(jī)上的合力達(dá)到平衡,同時(shí)飛機(jī)在一個(gè)角度上保持穩(wěn)定。因飛機(jī)有一定的角度,機(jī)翼升力降低,所以駕駛員或自動(dòng)駕駛系統(tǒng)會(huì)給出升降舵上升的命令。 (3) The ailerons are located on the outboard trailing edge of each wing. Other aileron components are located in 3 main areas: . Flight deck The control wheels are located in the forward portion of the flight deck. The aileron trim switch is located on the control stand. . Wheel well area The aileron power control units(PCU, convert a pilot or autopilot mechanical driven input to a hydraulic power driven mechanical output to drive the aileron) are located on the forward wall of the main wheel well. The autopilot aileron actuators are located on the forward wall of the main wheel well. The aileron position sensor provides two feedback postion signal from the aileron system to the A/P system. . Lower nose compartment The control drum and bus drum are connected to the control wheel, located in the lower nose compartment. The roll CWS force transducer is connected between the bus drum and the control drum, the output of the force transducer provides signals to the autopilot. The aileron force limiter limits control wheel movement during A/P operation, the control wheel rotation is limited to 17°with flaps up and 25°with flaps down.

(4) To understand elevator poeration consider the airplane balanced about the center of lift (CL). The center of gravity (CG) is shown forward of the center of lift. The stabilizer provides a counter force to the CG. The stabilizer may be trimmed to changer the force as required to maintain balance. The elevators are used to change the pitch attitude. Moving the elevators out of their faired position causes the airplane to change the pitch attitude about the lateral axis. The amount of elevator movement establishes the airplane pitch rate. When the desired attitude is reached, the elevators are faired and the air-plane maintains the new pitch attitude.
