Modes of Operation
Step Procedure
3 With the autopilot engaged, set the speed reference on the
coupled side PFD to the reference IAS/Mach number, using
the SPD knob.
4 Advance throttle position to attain climb power.
Speed Mode Engagement Procedure
Table 8--7
The aircraft climbs toward the preselected altitude, maintaining the
speed reference. The amount of throttle position change varies the
aircraft rate of climb.
In the SPD mode, all armed pitch flight director modes are valid, but
capture of any armed pitch mode overrides the SPD mode.
NOTE: When the SPD mode is selected, the speed command bug
is displayed on the airspeed display.
