Coding Rules for Facility Coverage

IdentifierData Encoding RuleJustificationData Verification Rule (UID)Remarks
NAV-801Afacility coverage should be provided for each NavaidEquipment at least as NavaidEquipment.annotation.PANS-AIMTBD
NAV-802If RadioFrequencyArea.type equal-to 'COV' then CircleSector.outerDistance is mandatory.EADTBD
NAV-803If RadioFrequencyArea.type equal-to 'SCL' then RadioFrequencyArea.angleScallop is mandatory.EADTBD
NAV-804CircleSector.outerDistance must be greater than CircleSector.innerDistanceEADTBD
NAV-805If CircleSector.upperLimit is specified, then CircleSector.upperLimitReference is mandatory.EADTBD
NAV-806

If CircleSector.lowerLimit is specified, then CircleSector.lowerLimitReference is mandatory.

EADTBD
NAV-807If the unit of measurement of CircleSector.upperLimit has the value ''FL'' or ''SM'', then the attribute CircleSector.upperLimitReference must have the value ''STD'' (standard pressure).EADTBD
NAV-808If both CircleSector.lowerLimit and CircleSector.upperLimit are specified, then the value of the lower limit must be smaller than or equal to the value of the upper limit
(when converted to a common unit of measurement and reference system).
EADTBD
NAV-809If the unit of measurement of CircleSector.lowerLimit has the value ''FL'' or ''SM'', then the attribute CircleSector.lowerLimitReference must have the value ''STD'' (standard pressure).EADTBD
NAV-810RadioFrequencyArea.angleScallop may be specified only for VOR or TACAN.EADTBD
NAV-811The RadioFrequencyArea.angleScallop may be specified only if RadioFrequencyArea.type is ''SCL'' or ''COV''.EADTBD
NAV-812If a CircleSector is defined for a RadioFrequencyArea the CircelSector.fromArc is mandatory.Data consistencyTBD

If a CircleSector is defined for a RadioFrequencyArea the CircelSector.toArc is mandatory.Data consistencyTBD
NAV-813If a CircleSector is defined for a RadioFrequencyArea the CircelSector.arcDirection is mandatory.Data consistencyTBDSee Open Question
NAV-814If a CircleSector is defined for a RadioFrequencyArea the angleDirectionReference is mandatory.Data consistencyTBDSee Open Question
NAV-815If a CircleSector is defined for a RadioFrequencyArea the CircelSector.type is mandatory.Data consistencyTBD

titleOpen Question:
Shall there be a rule that for VOR and TACAN it shall be RDL, For NDB magnetic or True bearing, etc.?
