VNAV SPD

VNAV SPD works similar to FLCH SPD but the speed is managed by the FMS and the speed window is blanked.

To engage VNAV SPD:

Selected a higher altitude in the MCP altitude window. To do this move your mouse cursor over the altitude knob and use your scroll wheel.

If VNAV was already engaged before click the altitude select knob

If not: Press the VNAV button to engage VNAV.

Note - VNAV SPD can also be activated in the descent, when the aircraft is above the programmed vertical profile for example or when the speed is more important than the vertical path, e.g. when slowing down.

VNAV SPD的工作方式與FLCH SPD相似，但是速度由FMS管理，并且速度窗口為空白。

啟用VNAV SPD：

VNAV SPD

在MCP高度窗口中選擇了更高的高度。為此，將鼠標光標移到海拔旋鈕上，然后使用滾輪。

如果在單擊海拔選擇旋鈕之前已經使用了VNAV

如果不是，請執(zhí)行以下操作：按下VNAV按鈕以啟用VNAV。

注意 -例如，當飛機高于設定的垂直計劃時，或者當速度比垂直路徑更重要時(例如，減速時)，也可以在下降中激活VNAV SPD。
