135.  The aircraft engines, the APU or a ground air source can supply compressed air to the pneumatic system. The distribution system supplies the compressed air from the different sources to the user systems.飛機發動機、APU、地面氣源能夠向氣動系統提供增壓空氣。分配系統將不同來源的增壓空氣提供到用戶系統

136.  The aircraft pressure sensor delivers an electric analog signal representative of

aircraft pressure. This analog signal is converted to digital information to be processed by the digital section.飛機壓力傳感器發送一個代表飛機外壓力的模擬電子信號。這個模擬信號轉換為數字信息,并由數字部分進行處理。

137.  The aircraft wing is a continuous structure which goes through the fuselage between Frames 36 and 42. The center wing is part of the fuselage and gives attachment points for the outer wings.飛機機翼是一個連續的結構體，通過機身隔框 36和42之間。中央翼是機身的一部分，為外側機翼提供安裝點。

138.  The APU engine is located in the aft end of the fuselage, behind the pressure bulkhead and below the horizontal stabilizer. The APU engine is completely enclosed in a titanium shroud.APU發動機安裝于機身尾部、壓力隔板后面及水平安定面下方。APU發動機被完全地封進一個鈦防護罩中。

139.  The APU usually takes its fuel supply from the LH engine-feed line, but when the cross-feed valve is open, the RH engine-feed line can also supply the APU with fuel.APU通常從左發動機供油管路獲得燃油，如果交輸活門打開，右發動機供油管路也可以供應 APU燃油。

140.  The basic yaw control is hydro-mechanical as well as the alternate horizontal stabilizer

control, thus providing the ability to keep the aircraft in flight during a temporary complete loss of electrical power.基本的偏航操縱是液壓機械式，如同備用水平安定面操縱。因此，當飛機電力突然完全消失，飛機仍然具有保持飛行的能力。

141.  The Bulk cargo compartment has tie down/ attachment points for the door nets and for the nets and straps which keep the bulk cargo in place.散裝貨艙安裝有連接門網和散貨固定網及束帶的系留點。
