基本模式 Basic Mode

When the first flight director is set to ON or the autopilot is engaged with the flight directors in the OFF position, the basic lateral and vertical mode are selected automatically.

On the ground the lateral and vertical modes TO/GA are selected. These guide the aircraft wings level and to the MCP speed + 10kts for takeoff.

The basic lateral mode is wings level (LVL) or bank hold (ATT) depending if the current bank angle is above 6° to either side. Wings level (LVL) is followed by heading hold (HDG HOLD) as soon as the bank angle is reduced to zero and the present heading at that time is maintained.

Vertically the basic mode is Vertical Speed hold (VS)

當(dāng)?shù)谝粋€(gè)飛行指引儀設(shè)置為ON 或 自動(dòng)駕駛儀已經(jīng)啟用同時(shí)飛行指引儀處于OFF位置時(shí)，基本的橫向和垂直模式會(huì)被自動(dòng)選擇。

在地面上，橫向和縱向模式都被選到了TO/GA。這些將引導(dǎo)飛機(jī)機(jī)翼水平并以MCP速度+ 10kts起飛。

基本的橫向模式是機(jī)翼水平(LVL)或傾斜保持(ATT)，這取決于當(dāng)前傾斜角度是否大于任一側(cè)的6°。一旦傾斜角減小到零并保持當(dāng)時(shí)的航向，則在機(jī)翼水平(LVL)之后跟隨航向保持(HDG HOLD)。

垂直方向上的基本模式是垂直速度保持(VS)
