花了點時間翻閱手冊，但是已經是好幾年前的舊資料
打著這些時心裡是越來越心虛，一直思考著究竟在駕駛艙裡發生了什麼事
依照飛安會初期報告的FDR指出:
收到2號發動機警告，卻是收1號發動機油門進行ENG RESTART
在收到組員報告確認2號發動機熄火後還是將1號發動機Condiation Lever 推到FUEL SO
所有名詞我就不一一解釋了，因為資料有點舊，非常可能有更動，僅供參考
SINGLE ENG OPERATION
LAND ASAP
PWR MGT(both).....................................TO if necessary then MCT
FUEL PUMP AFFECTED.....................................................OFF
DC GEN affected........................................................OFF
ACW GEN affected.......................................................OFF
PACK affected..........................................................OFF
BLEED affected.........................................................OFF
OIL PRESSURE ON FAILED ENGINE......................................MONITOR
----------------------------------我是分隔線----------------------------------
ENG RESTART IN FLT
PROCEDURE
ENG RESTART IN FLT
FUEL SUPPLY..........................................................CHECK
CL.................................................................FUEL SO
PL......................................................................FI
CAUTION: After ATPCS sequence PWR MGT rotary selector must be set to MCT
position before engine restart in order to cancel propeller feathering.
ENG START rotary selector......................................START A & B
EEC ......................RESET if necessary or DESELECT if FAULT persists
START pb................................................................ON
At 10 % NH:
CL.....................................................................FTR
RELIGHT............................................................MONITOR
CL....................................................................AUTO
PL..................................................ADJUST TO OTHER ENGINE
ENG START rotary selector..................................OFF/START ABORT
SYSTEMS affected...................................................RESTORE
-------------------------------------我是分隔線------------------------------
ENGINE FLAME OUT
An engine flame out may be recognized by:
-Sudden dissymmetry
-TQ decrease
-Rapid ITT decrease
PROCEDURE
ENGINE FLAME OUT
PL......................................................................FI
█ If NH drops below 30% (no immediate relight)
CL....................................................FTR THEN FUEL SO
█ If damage suspected
FIRE HANDLE ...................................................PULL
SINGLE ENG OPERATION PROCEDURE................................APPLY
█ If no damages are suspected
ENG RESTART IN FLT PROC.......................................APPLY
█ If unsuccessful
SINGLE ENG OPERATION PROCEDURE.............................APPLY
註:CL=Condition Lever PL=Power Lever FI=Flight idle

推 welkin7: 02/07 11:18
推 followwind: 請問ㄧ下，CL那邊那個FTR是Fail To Run的縮寫嗎？ 02/07 12:30
→ chewie: 下一階段可能真的要從飛機殘骸研究證據了... 02/07 12:58
→ fbice: CL的FTR是指feather 也就是把槳葉擺在順槳位置 02/07 13:11
推 followwind: 所以在Engine Flameout時的SOP是把可能受損的引擎降到 02/07 13:17
→ followwind: Idle, 然後CL先Feather再Shut out. 如果懷疑引擎受損 02/07 13:18
→ followwind: 就拉Fire Handle然後照單引擎運行的步驟. 如果引擎沒 02/07 13:21
→ followwind: 受損的話就先照飛行時重啟引擎步驟來嘗試重啟引擎, 如 02/07 13:22
→ followwind: 過不成功就照單引擎運行的步驟. 02/07 13:23
→ followwind: 可是這樣還是無法解釋為什麼會先去把正常運行的發動機 02/07 13:24
→ followwind: CL去Fuel SO啊... 02/07 13:25
推 oneyear: 所以真的是因為不明原因拉到錯的?還有這SOP是不是該改成 02/07 13:29
→ oneyear: 到安全高度時再處理到idle?! 02/07 13:30
推 tlm: 我還是滿想知道Objective TQ是什麼 因為從時間軸來看 第一個 02/07 13:59
→ tlm: 跳開正常值的參數 是一號引擎的Objective TQ 如果它是某種 02/07 14:00
→ tlm: 扭力值 那應該也是代表引擎有問題吧 一號引擎 真的是完全正常 02/07 14:01
→ tlm: 嗎? 會不會機師重啟一號引擎 是別的因素 而在這個想法的過程 02/07 14:02
→ tlm: 中 才又發生了二號引擎的故障 02/07 14:02
推 chewie: 還是要等其他調查結果再判斷比較好 02/07 14:05
→ aklim: 我也想知道Objective TQ到底是代表什麼 02/07 16:26
推 atguc: 一般情況下 起飛時objective TQ為90% ENG 1 Objective TQ 02/08 21:29
→ atguc: 增加為100%應該是因為ATPCS系統偵測到ENG 2 fail所做的動作 02/08 21:30
