This operation allows the operator to correct the erroneous fields upon the reception of an FPL or IFPL message.
The FPL message is the flight plan as filed with an ATS unit by the pilot or a designated representative, without any subsequent changes.
The following FPL fields can be corrected through this operation:
callsign aircraftIdentification (F7a), assignedSSRCode /Mode (F7b/c), flightRules (F8a), flightType (F8b), numberOfAircraft (F9a), aircraftTypeICAOIdentifier (F9b), wakeTurbulenceCategory (F9c), NCAEquipment (F10a), surveillance equipment (F10b), departureAerodromeDesignator (F13a), estimatedOffBlockTime (F13b), enRouteCruiseSpeed (TAS or Mach) (F15a), requestedFlightLevel (F15b), icaoRoute (F15c), destinationAerodromeDesignator (F16a), totalEstimatedElapsedTime (F16b), alternativeDestinationAerodromeDesignator (F16c), otherInformation (F18), supplementaryInformation (F19).
The following IFPL fields can be corrected through this operation via decoded data:
departureAerodromeDesignator (ADEP), destinationAerodromeDesignator (ADES), aircraftIdentification (ARCID), aircraftTypeICAOIdentifier (ARCTYP),
NCAEquipment (CEQPT), estimatedOffBlockDate (EOBD), estimatedOffBlockTime (EOBT), fillingTime (FILTIM), ifplid (IFPLDID), numberOfAircraft (NBARC), surveillance equipment (SEQPT), dataSourceId (SRC), assignedSSRCode/Mode (SSRCODE), wakeTurbulenceCategory (WKTRC), totalEstimatedElapsedTime (TTLEET), flightRules (FLTRUL), flightType (FLTTYP), alternativeDestinationAerodromeDesignator (ALTRN1/2), icaoRoute (ROUTE), requestedFlightLevel (RFL), enRouteCruiseSpeed (SPEED / MACH), rtepts (RTEPTS), sidDesignator (SID), starDesignator (STAR).
Other fields managed by this operation are included in specificADEXPField, otherInformation and supplementaryInformation, and listed in previous section "Operations"..
