Accept/Reject Uplinks
ATC messages requiring an accept or reject response display those options on the
EICAS display. The MFD message page displays ACCEPT, STANDBY, REJECT
REASONS, and REJECT keys at the bottom. Select ACCEPT or REJECT to
respond to the uplink message. The REJECT REASONS key can be selected to
inform ATC why the message is being rejected.
Company messages can also be accepted or rejected on the message page.
After making a selection, the status changes to ACCEPTING/REJECTING while
the response is transmitting. When the communications network sends a response
indicating that the message was received, the message status changes to
ACCEPTED/REJECTED. After a message has been accepted or rejected, a
CANCEL key is displayed at the bottom of the page. Selecting CANCEL clears
the message from the display. Rejected messages are automatically removed 5
seconds after the message status changes to REJECTED.
The ACCEPT, CANCEL, and REJECT buttons on the glareshield perform the
same function as the same keys on the MFD.
ATC Datalink
ATC datalink communicates with participating air traffic control centers, reducing
the need for VHF voice communications. Airplane situation reports, route
changes, speed and vertical clearances, and voice contact requests can be sent or
received as appropriate. The COMM display ATC menu selection allows display
of downlink message pages.
Uplink and downlink messages are stored. All messages are assigned the time of
receipt/transmission and are printable.
ATC datalink requires manual logon to a participating ATC facility. Once logged
on, transfer to adjacent ATC facilities is normally automatic.
Crew Feedback
ATC uplinks containing clearance data that the crew can set on the MCP or EFIS
control panel have a crew feedback display function. When the message is
displayed on EICAS or the message page, the data values change from white to
green when properly set by the crew. Data which provides feedback is:
• MCP speed
• MCP heading
• MCP altitude
• barometer setting
• transponder code
• VHF frequency
• HF frequency
