Aerodrome Mapping Databases supporting taxi routing functions

The joint RTCA SC-217/EUROCAE WG-44 committee completed the latest revisions of the AMDB user requirements and interchange specifications DO-272C and DO-291B in 2011. One of the major novelties is the introduction of the ASRN. The ASRN supports manual editing of taxi routes, data link transmissions of taxi routes, and highly detailed display of taxi routes in the cockpit.
