GROUND
, (go to ground).
•
The pressure in the system changes towards ground. The ground pressure replaces the
static or altitude aim value; zero replaces the airspeed aim.
Note:
If required, new rates of change can be entered while going to ground.
•
Wait for the display to show zero airspeed and atmospheric pressure.
•
The display changes to "safe at ground" for 5 seconds then to "aircraft safe at ground"
with the message "confirming system settings .....".
Note:

operation automatically re-checks the ADTS controller settings,
the pumps start and the display shows:
No pressure is applied to the output ports during this operation.

•
When the airspeed is zero and the Ps channel pressure is close to ground, the
atmospheric pressure is re-measured to update the recorded ground pressure (QFE).
•
Press

to continue with normal operation; the ground and zero valves
automatically close.
