Modes of Operation
VERTICAL SPEED HOLD MODE
The vertical speed hold mode automatically maintains the aircraft at a
pilot--selected vertical speed. To engage vertical speed hold, the pilot
maneuvers the aircraft to the desired climb or descent attitude,
establishes the vertical reference, and pushes the VS button on the
flight guidance controller. The reference vertical speed can be changed
by pushing the TCS button on the control wheel, maneuvering the
aircraft to a new vertical speed reference and releasing the TCS button.
The vertical speed reference can also be changed with the pitch wheel
on the pitch turn controller.
When the vertical speed mode is engaged, the following is displayed,
