The diagram below shows the AIXM classes, including the relevant data types, needed to encode that information The main classes are Azimuth and Elevation which is a specialisation of the NavaidEquipment.

| Identifier | Data Encoding Rule | Justification | Data Verification Rule (UID) | Remarks |
|---|---|---|---|---|
| MLS-101 | The Azimuth.designator attribute is mandatory. | Minimum AIP data set | TBD | |
| MLS-102 | The Azimuth.channel attribute is mandatory. | Minimum AIP data set | TBD | |
| MLS-103 | The Azimuth.location property is mandatory. | Minimum AIP data set | TBD | |
| MLS-104 | The Elevation.location property is mandatory. | Minimum AIP data set | TBD | |
| MLS-105 | The Elevation.angleNominal atribute is mandatory. | PANS-AIM | TBD | |
| MLS-106 | The Elevation.angleAccuracy attribute should be provided. | PANS-AIM | TBD | |
| MLS-107 | The Elevation.angleMinimum attribute should be provided. | PANS-AIM | TBD | |
| MLS-108 | Either the Azimuth.magneticBearing or the Azimuth.trueBearing attribute shall be provided. | Minimum AIP data set | TBD | |
| MLS-109 | If the Azimuth.magneticBearing is provided than the Azimuth.magneticBearingAccuray should be provided. | PANS-AIM | TBD | |
| MLS-110 | If the Azimuth.trueBearing is provided than also the Azimuth.trueBearingAccuray should be provided. | PANS-AIM | TBD | |
| MLS-111 | If Navaid.type equal-to 'MLS or 'MLS_DME' the Navaid.signalPerformance shall be provided. | PANS-AIM | TBD | |
| MLS-112 | The Navaid.signalPerformance and the related RunwayDirection.precisionAppraochGuidance shall be consistent. | Data consistancy | TBD | For example if signalPerformance is CAT IIIA also the precisionAppraochGuidance shall be CAT IIIA. |
| MLS-113 | If Navaid.type equal-to 'MLS' or 'MLS_DME' it must have exactly one NavaidEquipment which is a Azimuth. | Data consistancy | TBD | |
| MLS-114 | If Navaid.type equal-to 'MLS' or 'MLS_DME' it must have exactly one NavaidEquipment which is a Azimuth. | Data consistancy | TBD | |
| MLS-115 | The value of the DME.channel of the related DME must be paired with the Azimuth.Channel as described by Table A, ICAO Annex 10, Vol.1. | EAD | ||
| MLS-116 | The Azimuth.location must be plausibly close (less than 1 KM) to that of the end of the related (through Navaid.runwayDirection) RunwayDirection. | EAD / Data consistancy | TBD | |
| MLS-117 | The difference between Azimuth.magneticBearing and the related RunwayDirection.magneticBearing (through Navaid.runwayDirection) cannot exceed 10 degrees. | EAD / ICAO Doc 8168, PANS OPS | TBD | |
| MLS-118 | The difference between Azimuth.trueBearing and Azimuth.magneticBearing has to be consistent with the value of the AirportHeliport.magneticVariation of the related AirportHeliport ( trough Navaid.servedAirport), taking in consideration the current date and the annual rate of change (AirportHeliport.magneticVariationChange). | EAD | TBD | |
| MLS-119 | The Elevation.location must be plausibly close (less than 1 KM) to that of the threshold of the related (through Navaid.runwayDirection) RunwayDirection. | EAD | TBD | |
| MLS-120 | Elevation.angleNominal must be greater than Elevation.angleMinimum. | EAD/ ICAO Annex 10, Vol. 1 | TBD |

As there is hardly any MLS installation in the world remaining, it is not considered necessary to provide an example of a MLS in the scope of the DONLON AIXM AIP data set.
