AIXM supports the encoding of schedules that contain both repetitive time periods and occasional occurrences. The coding guidelines for schedules/timetables can be found in: AIXM Coding Overview - Common Coding Rules - Schedule [TSH]Common coding patterns. These general coding guidelines for schedules are also applicable to Digital NOTAM Events. However, based on the limitations specified in the OPADD document, only a subset of schedules is allowed for temporary events published by NOTAM. The limitations are described further down in this section.

The information items that may occur in the definition of schedules are identified in the diagrams described in the Common Coding Rules - Schedule [TSH]Common coding patterns, section Common coding patterns. For use of "daily", "on date" and "date ranges" templates please refer to Common coding patterns - "Daily" schedules diagram. For use of "on weekday" and "from weekday...to weekday" please refer to Common coding patterns - "Weekday" schedules diagram. Each diagram is accompanied by the corresponding graphical elements explanation.

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. These rules shall be used as complementing the General coding rules for Schedules defined in AIXM Coding Overview - Common Coding Rules - Schedule [TSH]Common coding patterns. In case of contradiction, the rules described below are superseding the general ones.
