In 2000, ATA Spec 100 and ATA Spec 2100 were incorporated into ATA iSpec 2200. The ATA Technical Information & Communications Committee (TICC), recognising the synergies between ATA Spec 100 and ATA Spec 2100, developed this new consolidated specification for guidance in preparing technical documentation in support of aircraft maintenance. It includes the industry-wide approaches for numbering aircraft systems, as well as content and formatting approaches for the documentation, regardless of delivery medium.
