發動機及液壓參數用發光二極管顯示在兩個發動機指示面板上。
發動機在中央面板上顯示及控制包括以下內容：
·N1 顯示—用轉速百分比指示風扇轉速
·N2 顯示—用轉速百分比指示高壓壓氣機轉速。
·排氣溫度指示
1. 用°C 指示排氣溫度。
2. 如果發動機超出紅線，N1，N2 上方的紅燈及發動機排氣溫度指示燈
亮。
·燃油流量指示
用每臺發動機每小時總的消耗重量指示燃油量。
FUEL FLOW/FUEL USED 開關用于改變FUEL FLOW/FUEL USED 的
顯示模式，10 秒后FUEL USED 顯示恢復到FUEL FLOW。
·FUEL USED RESET—顯示一個順序：上次重置后上電后的燃油使用，
然后是000，最終燃油流量。
·發動機滑油壓力指示—用PSI 指示發動機滑油壓力。
·發動機滑油溫度指示—用°C 指示發動機滑油溫度。
·發動機滑油量指示—用百分比顯示發動機滑油量。

二、TEXT
(1) the auxiliary power unit (APU) is used for providing:
1) compressed air for engine starting.
2) Compressed air to the air conditining system on the ground or in flight.
3) Electrical power to the airplane electrical system on the ground or in
-flight ,(we will discuss APU electrical power in the next lesson).
輔助動力裝置APU 被用于提供以下：
1) 為發動機起動提供壓縮空氣
2) 在地面或飛行中為空調系統提供壓縮空氣
3) 在地面或飛行中為飛機電源系統提供電源
(2) 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. The air inlet door is located on
the right side of the aft fuselage for air entrance. The airflow is split into
two paths, one for the engine and the second for the accessories cooling.
The cooling air exhaust overboard through a hole in lower shroud. The
exhaust ducting is cooled by four air inlets around the jet pipe. Fuel is
supplied through a shrouded line from fuel tank. Bleed air from the APU
is supplied to the pneumatic system through a bleed valve, the bleed air
can be used to perate either of the two air —conditioning packs or for
main engine starting. The APU is readily accessible for inspection,
maintenance or removal through a large door in the fuselage directly
below it . removal is accomplished by lowering the assembly with a
simple hoist and cable system.
The APU is a singe shaft gas turbine engine with a two stage centrifugal
compressor, a single combustion chamber and one radial inflow turbine.
The accessories group, driven by the gear box , is at the front of the unit.
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。空氣進口安裝于機身后部右
側。進入APU 的空氣被分成兩個通路，一個供給發動機，另一個供
給容易接近的冷卻器。冷卻空氣通過保護罩下方的一個孔排放出去。
排氣管道被四個圍繞噴射管道的進口空氣冷卻。燃油從燃油箱通過一
個帶保護的管道提供。從APU 出來的引氣通過一個引氣閥門被提供
到增壓系統，引氣可以被用來控制兩個空調組件中的任一個，也可用
于發動機起動。APU 通過它正下方機身的一個大的口蓋很容易接近，
