This function enables lateral and vertical flight plan data as well as performance data to be
exchanged between the aircraft and a ground station. The aircraft may send flight plan
requests for active and secondary flight plan. (downlink messages). The ground station
may send flight plan and performance data (uplink messages) either under aircraft request
or automatically without any request.
Each uplink message concerns either the active or secondary flight plan but never both
flight plans at the same time. The data sent to the aircraft are checked for flight plan
consistency.
A MCDU message comes up when an uplink message is received. "ACT (or SEC) RTE
UPLINK".
If an error prevents the decodind process of the message, "INVALID RTE UPLINK" is
displayed on MCDUs.
Au uplink message can be routed to the active flight plan if no engine is started and no
active flight plan exists. Otherwise, it is routed to the secondary. The crew will insert it into
the secondary flight plan or will reject it using the CLR key.
Note : The flight plan may also be initialized using the ACARS function page selected from
