The AFTNCorrectionManagementProvider Service Interface manages the operations performed by the FDO to correct erroneous AFTN messages concerning in-coming flight plan that cannot be processed automatically by the system.
It covers the following cases:
- AFTN Modification messages: CHG, CNL, DLA, ARR, DEP (ICAO format), ICHG, ICNL, IDLA, IARR, IDEP, IACH (ADEXP format). In this case, it may be necessary to associate a FP to these messages to be able to correct them successfully.
- AFTN Creation messages: FPL (ICAO format), IFPL, IAPL (ADEXP format).

Operations

This operation allows the operator to correct the erroneous fields upon the reception of a CHG or ICHG message.
Whenever a change is made to the data contained in a Flight Plan message already sent to the ATSUs concerned with the flight, they must all be notified. It is particularly important to notify changes of Flight Level or Flight Rules, whether the change is made before departure or en-route. Such notification may be done by phone or ATS/DS when possible; otherwise it must be done by means of a modification message sent to AFTN.

The following CHG fields can be corrected through this operation:
CHG content: callsign aircraftIdentification (F7a), assignedSSRCode /Mode (F7b/c), departureAerodromeDesignator (F13a), estimatedOffBlockTime (F13b), destinationAerodromeDesignator (F16a), totalEstimatedElapsedTime (F16b), otherInformation (F18), amendments of other ICAO fields (F22), alternativeDestinationAerodromeDesignator (F16c).
In CHG, F22 should only amend F7b/c, F8, F9, F10, F13b, F14, F15, F16, F18, F19.

The following ICHG fields can be corrected through this operation via decoded data:
departureAerodromeDesignator (ADEP), destinationAerodromeDesignator (ADES), aircraftIdentification (ARCID), aircraftTypeICAOIdentifier (ARCTYP), NCAEquipment (CEQPT), estimatedOffBlockDate (EOBD),

Operations

This operation sends the erroneous AFTN messages information for FDO correction.

Upon reception of an AFTN erroneous message associated to a given SFPL, this message is referred to FDO.

Only the following AFTN messages are referred to FDO by CCS (the other are not yet within the scope of PJ16): ACH, APL, ARR, CHG, CNL, DEP, DLA, FPL, IACH, IAPL, IARR, ICHG, ICNL, IDEP, IDLA, IFPL.
The consumer can receive two other kinds of referred message: blocked and not checked.
The information referralType is used to differentiate an erroneous message referred for correction from a message "blocked" by FDM since an erroneous message for the same SFPL was already referred to FDO.

Operations

Operation to transmit the intention of releasing the flight according to the agreed transfer conditions.
Depending on the LoAs: e.g. expecting a further AssumeFlight operation or just waiting for a radio contact to release the flight.
This is an OLDI COF (Change Of Frequency) message equivalent.

This operation also offers the possibility to hand over the flight to another crossed responsibility than the expected one (eq. shortcut forceHandOver input). In that case, it is expected to provide explicitly the new responsibility traversal to which the transfer is performed, as well as the identifier of this responsibility (available in the SFPL ControlSector list).
This operation also offers the possibility to hand over the flight to a responsibility not in the list of crossed (eq. delegate input)..

Operation to input a dialogue with a new coordination proposal.
This service is to be used by either the upstream or the downstream controller.
When the proposal is initiated by the downstream, this is an OLDI CDN message equivalent. When the proposal is initiated by the upstream, this is mainly an OLDI RRV equivalent.
When the proposal is initiated by the upstream, it may be a RAP message equivalent if the downstream is not yet NEAR_PLANNING and if RAP transmission is off-line authorised. Else it may be an RRV message equivalent if the downstream is at least NEAR_PLANNING.
The input shall contain the identification of the SFPL, the receiving responsibility, the coordinationReference value (downstream or upstream proposal) and at least one of the following proposed coordination data:
- in case of downstream proposal: Transfer Flight Level, Route (including direct to a new point), Next SSR code, COP, Time on transition point.
- in case of upstream proposal: the Transfer Flight Level or the Route (including direct to a new point).

In both cases, the proposal input can also contain a Supplementary Flight Level, the boundary point type and, only when sent to another sector of the same ATSU, the following tactical instructions: Heading, Speed, ROCD and CFL (the application point of tactical instructions in coordinationProposal is considered IMMEDIATE).

The controller of the consulted responsibility receives a whatIF flight with the proposed coordination data and the coordination status of the transition is set to PROPOSED..

The request shall contain the responsibility to skip in the ControlSector list (respTraversalId).
The skipped LogicalCWP traversal is no more taken into account (from a frequency point of view); the upstream LogicalCWP transfers the flight directly to the downstream LogicalCWP.

closePointOut is used in response to a pointOut notification for formally notifying the system that the notification has been processed by the receiver.
This remains a local action between the receiver and his/her system without any OLDI equivalent message.
The originator controller is capable of ending the point session, while the designated controller is capable only to remove his OEs from the recipient list (and if there is no more recipient, the point session is ended).

The input of the point function shall contain the identification of the SFPL and the identification of one or several point target sector(s).
The use of a reason parameter written by the originator is only allowed for Point message sent to controller(s) of the same ATSU.
The main uses of the point function are:
- highlight: to support vocal exchanges during the co-ordination process. In such cases, the flight is designated by the giving position, and it is highlighted on the positions managing the pointed sector(s).
- manual distribution: to support the delivery of flight data to a chosen recipient:
- for information, if the recipient is not within the computed informed responsibility list (e.g. to check with an adjacent position the possibility to transfer the flight to it)
