6.4.1. Vertical Speed Mode
The vertical speed mode or SVS mode is the default vertical
mode that is activated when the autopilot is engaged (as long as an
altitude pre-select has not been entered).
When the autopilot is engaged it will synchronize to the vertical
speed being flown at that time. If the aircraft vertical speed is less
than 400 fpm in either direction, the autopilot will go to zero vertical
speed.
The SVS mode allows the user to select a desired vertical speed
for the autopilot to fly. The selected vertical speed can be adjusted
by toggling the joystick up for climb and down for descent. The
selected vertical speed moves in 100 fpm increments and is always in
feet per minute, irrespective of airspeed units set in the display.
Once the SVS is set the autopilot will continue climbing or
descending at the selected vertical speed until the user stops the
climb or descent. Figure 6.4.1a shows the SVS change from 0 to 600
fpm negative.
