自動推力(A / THR)主控

The Auto-Thrust (A/THR) (a.k.a. auto-throttle in other aircraft) controls the thrust to the engines. Depending on what the flight director vertical mode is the engine thrust is either constantly adjusted to maintain a target airspeed or the thrust is advanced to full climb thrust for a climb or retarded to idle thrust for a descent.

?Push the A/THR button to arm the auto thrust system

?Move the thrust levers to the climb detent to activate it.

The state of the auto thrust system is displayed in the top right corner of the primary flight display (PFD). When the text A/THR is in white color then the auto thrust is active. When the text is in cyan/blue the auto thrust has been armed but is currently not operating, e.g. because the pilot still has the thrust levers at idle or above the CLB detent (MCT with one engine failed). Setting the thrust levers into the climb detent changed the auto thrust state from armed to engaged.

The active thrust mode is shown in the top left corner of the PFD, in the first column. When it shows SPEED then the auto thrust system is controlling the airspeed and varies the thrust command to the engines accordingly. THR CLB or THR IDLE are shown when climb or idle thrust is commanded to the engines. When the mode shows MAN TOGA or MAN MCT or MAN FLX then the auto thrust is not active, you are manually overriding it with the thrust lever.

自動推力(A / THR)(在其他飛機上也稱為自動油門)控制發(fā)動機的推力。根據(jù)飛行指導(dǎo)者垂直模式的不同，可以不斷調(diào)整發(fā)動機推力以維持目標空速，或者將推力推進至全爬升推力以進行爬升，或者推遲至空轉(zhuǎn)推力以進行下降。

?按下A / THR按鈕武裝自動推力系統(tǒng)

?將推力桿移動到爬升制動器上以將其啟動。

自動推力系統(tǒng)的狀態(tài)顯示在主飛行顯示器(PFD)的右上角。當文本A / THR為白色時，自動推力處于激活狀態(tài)。當文本為青色/藍色時，自動推力已Arm，但當前未運行，例如，因為飛行員仍將推力桿置于空轉(zhuǎn)或高于CLB定位器(一臺發(fā)動機的MCT發(fā)生故障)。將推力桿設(shè)置到爬升制動器中會將自動推力狀態(tài)從裝備狀態(tài)更改為接合狀態(tài)。

主動推力模式顯示在PFD的左上角第一欄中。當顯示SPEED時，自動推力系統(tǒng)將控制空速并相應(yīng)地改變對發(fā)動機的推力指令。當向發(fā)動機發(fā)出爬升或怠速推力指令時，將顯示THR CLB或THR IDLE。當模式顯示MAN TOGA或MAN MCT或MAN FLX時，自動推力未激活，您正在用推力桿手動覆蓋它。
