Most Air Traffic Control datalink functions are accomplished on the MFD. The
multifunction keypad is used as an input device for downlink message forms.
Arriving ATC uplink messages are annunciated to the crew by the appearance of
the communications alert message "dot ATC" on the EICAS display, the ATC
uplink information on the ATC data block, and a Hi-Lo alerting chime. Following
alerting, the crew may view the message on the ATC data block and then select
the COMM display on the MFD. The ATC message displayed on the ATC data
block is repeated on the COMM display. A variety of clearance information may
be uplinked from ATC, including clearances such as headings, altitudes and
speeds, as well as route clearance data.
In the ATC data block message, the words ACCEPT and REJECT are displayed
to indicate that the crew must either accept or reject the clearance. The ACCEPT
or REJECT switches on the glare shield or the soft keys on the COMM display
can be used to complete this action. When a clearance is of a type that can be
loaded into the FMC, LOAD FMC buttons appear on both the COMM display and
the CDU help window. The crew may accomplish the FMC loading or
accept/reject actions in either order. However, loading the FMC first provides the
opportunity to view the clearance on the ND map display as a flight plan
modification prior to acceptance. Selection of either LOAD FMC prompt causes
the clearance to be loaded into the FMC and displayed on the CDU as a flight plan
modification. The message ROUTE X UPLINK LOADING is displayed in the
CDU help window and on the COMM display during loading.
