AMC1 ACNS.E.TAWS.030 Terrain information display ED Decision 2022/008/R (a) Terrain data should be displayed in the maximum field of view. Terrain that is more than 600 m (2000 ft) below the aeroplane’s elevation need not be depicted. (b) If terrain alerting information is displayed on a weather radar, an Electronic Flight Instrument System display, or other compatible display system available on the flight deck, then the TAWS information should be displayed in a manner consistent with other information (e.g. range, colour coding, symbology). (c) When Auto-range switching is provided, an auto-ranging display should be designed so that it is evident to the flight crew that the range has been automatically selected. The range selected for auto-ranging should clearly depict the threat on the display. Manual reversion to a selected range should be simple. [Issue: CS-ACNS/4]
