Logon page
To initiate a LOGON, an ATN connection must first be established by entering
ATN airspace. When ATN is connected, push the LONGON/STATUS LSK on the
CPDLC MENU page. This causes the LOGON/STATUS page to show on the
display. A LOGON request initiated by the pilot followed by a ground LOGON
response is required to enable the system to accept activation of a CPDLC
connection from the ground. Once the CPDLC connection has been established,
all other CPDLC pages in the application become enabled.
Flight ID, Origination Station, and Destination fields will be prefilled with system
data, if available. When system data is available, manual entry of data into these
fields is not allowed. Once the Flight ID, ORIG STA, DEST STA and facility have
been verified, push the SEND LOGON* LSK to initiate the LOGON. The
LOGON IN PROGRESS message is displayed on the LOGON/STATUS page
while the system sends the LOGON request to the ground and waits for the ground
response. After receiving the appropriate response from the ground network, the
message LOGGED ON is displayed and the LOGOFF* selection becomes
available.
Once the LOGON is complete, any change to the pre-filled data by the controlling
function (FMS or radio tuner) generates a message stating values have changed,
and an UPDATE LOGON* selection is displayed. To update the LOGON
information, push the UPDATE LOGON* LSK to transmit the new information
to the ground station.
Note: FLT ID cannot be changed after a LOGON without first selecting
*LOGOFF.
