If required data are missing, the requestCreateSFPL input is rejected.
A dedicated manual input shall be used to create an abbreviated SFPL (cf. requestCreateAbbreviatedSFPL).
However a requestCreateSFPL input may degenerates into the creation of an abbreviated SFPL in the following 2 cases:
1) failure of any route semantic check
2) presence of all the mandatory data but impossibility to determine Initial Conditions, due to the flight never intersecting the TP Area.
Moreover CCS creates abbreviated flight plans for SFPL related erroneous messages (received on external OLDI or AFTN lines or created manually by controllers), instead of referring erroneous messages to FDO, if at least the callsign is available (configurable option). The APL is created including the valid ICAO data given in the input.
