Flight directors are simultaneously turned on by either selecting a vertical mode,
selecting a lateral mode, or by engaging the autopilot. Flight director selection activates
all flight control mode annunciations and presents steering commands for the selected
mode(s). When both flight directors are turned on, by engaging the autopilot, basic
modes (pitch and roll) are automatically selected. When both flight directors are turned
on, by selecting a vertical or lateral mode, basic modes are automatically selected for
the other axis.
Transfer mode controls the routing of flight guidance commands to the autopilot and
flight directors. When transfer mode is selected, the copilot’s flight guidance command
drives both flight directors. When not transferred, the pilot’s flight guidance command
drives both flight directors.

B. Synchronization
Flight director synchronization is used to set the vertical and/or lateral reference to the
current flight value. Selecting synchronization has no effect if the autopilot is engaged.
The vertical reference being synchronized is IAS (if in IAS mode), MACH (if in MACH
mode), VS (if in VS mode), altitude hold memory (if in altitude hold, CLB or DES mode),
or pitch angle memory (if in pitch mode). Overspeed and vertical capture modes are
not affected by synchronization operation. The only lateral references that can be
synchronized are the bank and heading memories of roll mode.
