旅客氧氣系統(tǒng)為旅客及乘務員提供應急氧氣，系統(tǒng)包括旅客服務設備，控制及指示器。這個服務設備包括氧氣面罩盒、門鎖釋放作動筒，鎖定機械裝置、氧氣發(fā)生器及氧氣面罩。

(5) The passenger oxygen system can be activated automatically by high cabin altitude (low cabin pressure) or manually from the flight compartment.

旅客氧氣系統(tǒng)能夠被較高的客艙高度自動啟動，也能在駕駛艙人工啟動。

(1) the ice and rain protection system protects the airplane and aids the flight crew when operating under ice and rain conditions. Ice and rain protection is provided for: 1) wing leading edge slats outboard of each engine. 2) Flight compartment windows (heat, wiper, rain repellent). 3) Pitot static and temperature probes. 4) Alpha vanes. 5) Toilet drains.
防冰、防雨系統(tǒng)用于保護飛機及幫助機組在雨雪天氣下操作飛機。此系統(tǒng)為下列部件提供保護：
1
）發(fā)動機外前緣縫翼；

2
）駕駛艙玻璃窗（加熱、雨刷、防雨劑）；

3
）皮托靜壓管及總溫探頭；

4
）迎角葉片；

5
）廁所排水。

(2) Wing leading slats use hot air from the pneumatic system. Flight compartment windows are electrically heated. The wipers and rain repellent are used for providing clear vision. The pitot static probes, alpha vanes, drain masts, and toilet drains use electric heaters.

前緣縫翼用增壓系統(tǒng)的熱引氣加溫。駕駛艙窗口用電加溫。雨刷和防雨劑用來提供清晰視野。皮托靜壓探頭、迎角葉片、排水管及廁所排水都是用電加溫。

(3) The wing anti-ice system prevents ice buildup on the wing leading edge

slats, this system consists of air supply ducts, valves, terminal switches, controls and indications.
防冰系統(tǒng)可防止冰在縫翼前緣堆積，此系統(tǒng)包括供氣管道、活門、終端開關(guān)、控制及指示器。
(4) The window heat system improves the impact strength of the flight compartment windows and prevents fog and ice-buildup, this system consists of conductive coating in the window structure, heat control units, controls and indications.

窗口加熱系統(tǒng)提高了駕駛艙窗口的撞擊強度并防止霧和冰的堆積，此系統(tǒng)包括窗口結(jié)構(gòu)上的導電涂層、加熱控制組件、控制及指示器。

(5) The pitot static probes, temperature probe and alpha vanes provide air data information to the various using system, they are located on the left and right sides of the forward fuselage. Since all the probes and vanes are exposed to the airstream, internal heating is provided to prevent ice formation. Freezing could cause faulty inputs or possible loss of all data.
