Alternate Flap Extension - B767
Can anyone explain why during Alternate Flap Extension on the 767 the following point is stated as part of the QRH drill?
If flap lever is UP:
Flap lever . . . . . . . . . . . . . . . . . . . . . . . . . 1
This prevents uncommanded autothrottle
disengagement.
Cannot understand why the lever at Posn 1 stops uncommanded A/T disengagement.
Thx BarrowBoy
