ATS 3.39 TERRAIN AND OBSTACLE CHARTING

Work on SID and STAR phraseology changes and cancellation of level restrictions identified fundamental issues regarding ICAO procedures for terrain and obstacle clearance, primarily whether a restriction is ATC or terrain based. This WP proposed policies to clarify charting.


IFATCA Policy is:

All published altitude restrictions should indicate whether they apply for reasons of terrain avoidance.


See: Resolution B3 – WP 86 – Gran Canaria 2014

IFATCA Policy is:

ICAO documentation should provide clear and unambiguous language with regard to responsibility for terrain avoidance, including amendment to the Objectives of air traffic services to include the prevention of collisions between aircraft and terrain.


See: Resolution B2 – WP 85 – Gran Canaria 2014

IFATCA Policy is:

ATCOs should be provided with ATS surveillance tools and/or procedures to efficiently separate aircraft from terrain and obstacles.


See: Resolution B9 – WP 92 – Sofia 2015
