The Source FMS is indicated by an asterisk next to it. Any available
FMS can be manually selected by pressing the adjacent LSK. If
automatic (AUTO) selection is desired, the SELECTION METHOD
LSK will toggle between MANUAL and AUTO.
NOTE: It is important for the crew to ensure that the Source FMS is
not changed prior to an expected flight plan modification uplink.
If the Source FMS is changed prior to the uplink, the flight plan
information will need to be transferred to the new Source FMS
from the previously designated FMS.
Communications
Prior to entering Oceanic Airspace (and loss of VHF communications)
the crew should suspend VHF and transition to satellite
communication (See STATE under VHF DATA in the COMM
CONTROL section). The crew must enable VHF communications
once again when reentering a VHF-available region.
Current Time
On every UniLink screen above the RETURN option at LSK [5R], the
current UTC time is displayed.
SEND
When the SEND LSK is pressed, the request is placed into queue for
transmission. The delivery status of the message appears above the
SEND option. If data required for the message has not been entered
completely, the SEND option will display as inactive and if selected, a
pop-up window DATA REQUIRED will display (indicating the data is
insufficient).The SEND prompt will not display an arrow (indicating
active) until all required data is entered. Clear the pop-up window by
pressing any key or LSK.
