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..
