Introduction

This business DEX specifies in ISO 10303-239 (PLCS) terms, a set of in-service feedback messages that are exchanged between the MoD Engineering and Asset Management systems and industry partners to provide feedback on the usage and maintenance of aircraft and their components.

The specification of the content of each message is based on the OASIS Aviation Maintenance DEX (aviation_maintenance). MoD specific constraints are added by this Business DEX.

In addition, this DEX specifies the MoD specific extensions to the PLCS reference data that are to be used during each information exchange.
