Information cross mapping (ICM)

The term 'cross mapping' describes the process of moving data from existing 8-part AIP locations to fit the new 3-part structure and organisation as set out in ICAO Annex 15.

Specialist Knowledge

The requirement is that the text and data is cross mapped to the correct location for delivery of the first new AIP proof. To ensure that all data is moved to the correct location, a sound knowledge of aviation and of the content and structure of the old and new AIP formats is required. This specialist general aviation knowledge, combined with previous experience in AIP production is essential to successful ICM.

Sections of note that require such knowledge include the organisation of text and data present in AGA and RAC sections into the 3-part AD 2 sections and the movement of data from the 8-part COM section into 3-part ENR 4.1 and AD 2.18, 2.19 sections.

Tracking

All data extracted and moved to the new format AIP requires careful tracking. When moved, it is necessary to mark all data in the 8-part hard copy as extracted. Unresolved or changed data is marked differently. The system of tracking in hard-copy ensures that the changing status of AIP content during the conversion process is accurately recorded. The process requires a level of detail and accuracy often down to that of a single word or number to ensure that all moved data is accounted for.

It is the nature of conversion from 8 to 3-part, that requires such accurate tracking and in many examples, data from one 8-part section is required to complete more than one 3-part section, or from many 8-part sections to one 3-part.

The mapping process continuously changes as data queries are resolved and text moved or re-edited and as such, the status of AIP content requires accurate tracking to avoid error.
