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.
