GM2 AIS.OR.350 Terrain and obstacle data - General requirements

• ED Decision 2020/008/R found in: ATM/ANS Provision of Services (2017/373) (Mar 2025)

GM2 AIS.OR.350 Terrain and obstacle data – General requirements ED Decision 2020/008/R NAVIGATION APPLICATIONS (a) Terrain and obstacle data are intended to be used in air navigation applications such as: (1) ground proximity warning system with forward-looking terrain avoidance function and minimum safe altitude warning (MSAW) system; (2) determination of contingency procedures for use in the event of an emergency during a missed approach or take-off; (3) aircraft operating limitations analysis; (4) instrument procedure design (including circling procedure); (5) determination of en-route ‘drift-down’ procedure and en-route emergency landing location; (6) advanced surface movement guidance and control system (A-SMGCS); and (7) aeronautical chart production and on-board databases. Additional information on the use of terrain and obstacle data can be found in Appendix C to EUROCAE ED-98C. (b) The data may also be used in other applications such as flight simulator and synthetic vision systems, and may assist in determining the height restriction or removal of obstacles that pose a hazard to air navigation.
