REPORT Page (Prompt for Downlink of Position Report)
 Figure 012

 Manual sending of a flight plan report can be inhibited via the AOC policy file of the AMI (Ref. Para. D-(1)).
 (d) Performance data report The performance data report allows the transmission of performance data (weight, fuel, CG, etc.) from the active route to the ground. This message is sent automatically in response to a ground request for the performance data report.

 Response downlink messages

 (a)
 Rejection message When an error has been detected in an uplink message, the rejection message transmits an error code identifying the reason for rejecting the message.

 (b)
 Response message When an uplink message has not been rejected by the system, a response message is downlinked indicating whether it is accepted and inserted in the system by the pilot or cancelled by the pilot.

 (7)
 Broadcast data This is a set of data which is automatically broadcast by the FM on the output ACARS bus to the ATSU. Use of these data (selection of data, time of transmission to ground, etc.) is entirely defined by the ATSU. Activation or de-activation of downlink transmission is made by the OPC mini ACARS option or the OPC AOC option. This set of data is not printed by any FM function. Nevertheless, some data may be part of printed reports or uplink printouts. Transmitted data are:

 -Flight Number
 -City Pair
 -Active Data Base
 -Company Route
 -Active Waypoint
 -
Wind Velocity

 -
Wind Direction

 -Zero Fuel Weight
 -Block Fuel
 -Fuel On Board
 -Aircraft Gross Weight
 -Destination Runway (Ref. NOTE)
 -Alternate Destination
 -Estimated Time of Arrival
 -
Discrete AP Modes

 -
Discrete Flight Phase

 -
Aircraft Latitude

 -
Aircraft Longitude

 -
Aircraft Altitude

 -Roll Angle
 NOTE : Destination Runway is Destination Airport Ident (4 characters)
____ if no runway is defined; else it is Runway Ident (7 characters).
 B. ATC Functions
 CPDLC Applications
 (1)
 ATC Flight Plan Initialization/Modification The ATC flight plan initialization/modification function allows the crew to request an ATC clearance for a new route or a modified route, and to receive from the ATC center the route that the crew is allowed to fly. This function may be invoked on the ground as well as in flight. When the crew wants to initiate an ATC flight plan request, the requested route is first prepared in the secondary flight plan and then manually sent by the crew to the ATC center. When the ATC flight plan is received, it is stored automatically in the secondary flight plan after the crew has reviewed it and activated the LOAD function on the DCDU. An ATC flight plan uplink is composed of multiple elements which are processed as MCDU inputs. Two different types of ATC flight plan messages can be received:

 -flight plan uplink messages as follows: . Uplink message 80: cleared (route clearance) . Uplink message 83: At (position) cleared (route clearance) . Uplink message 79: cleared to (position) via (route clearance).
 -time constraints messages as follows: . Uplink message 51: Cross (position) at (time) . Uplink message 52: Cross (position) at or before (time) . Uplink message 53: Cross (position) at or after (time).

 ATC reports
 AN ATC report request is an ATC request to the crew to send a
 specific report downlink when a specific condition is met.
 ATC Reports function provides help to the crew by:

 -monitoring (upon ATSU request) the establishment of the condition to send the requested report,
 -informing the ATSU when the condition is actually met by providing it with the requested report downlink plus various reports depending on aircraft context.
 An ATC report request uplink message consists of one of the following referenced messages:
 -
report back on route (message 127)

 -
report leaving altitude (message 128)

 -
report level (altitude) (message 129)

 -
report passing (position) (message 130)

 -
report reaching (altitude) (message 175)

 -
report reaching block (altitude) to (altitude) (message 180). If the condition to send a report message to the ATSU is satisfied, the FM sends to the ATSU a message consisting of one of the following referenced messages:

 -back on route (message 41)
 -leaving (altitude) (message 28)
