AirportHeliport BASELINE as specified in theBasic Data for Airport/Heliport,
Runway BASELINE according to thecoding rules for Basic Data for Runway;
RunwayDirection BASELINE according to the coding rules for Basic Data Runway Direction.
It is assumed that the following principles have been followed for the encoding of BASELINE RunwayDirection.availability data (if available in the BASELINE data):
the operationalStatus has the value "NORMAL" (meaning that the facility operates with nominal parameters) for all RunwayDirection.ManoeuvringAreaAvailability that are part of the BASELINE data;
operations that are explicitly permitted have been encoded as ManoeuvringAreaUsage with type=PERMIT or type=CONDITIONAL (in case a PPR is necessary);
operations that are explicitly forbidden have been encoded as ManoeuvringAreaUsage with type=FORBID;
if the airport is exclusively reserved for certain operations, then the ManoeuvringAreaAvailability that describes this condition contains only ManoeuvringAreaUsage elements with type=RESERV;
in case of conflicts
the usages of type FORBID take precedence over usages of type PERMIT or RESERVE;
the usages of type PERMIT take precedence over the usages of type RESERVE;, including the coding rules for Runway usage.
Data encoding rules
The data encoding rules provided in this section shall be followed in order to ensure the harmonisation of the digital encodings provided by different sources. The compliance with some of these encoding rules can be checked with automatic data validation rules. When this is the case, the number of the encoding rule is mentioned in the data validation rule.
