ACNS.E.TAWS.070 Failure mode
ED Decision 2013/031/R
(a) A failure of the TAWS does not disable other protection functions (e.g. windshear or weather radar).
(b) The failure of the GPWS functions, except for power supply failure, input sensor failure, or other failures external to the TAWS functions, does not negatively alter the FLTA function, PDA function, or Terrain Display and vice versa.
(c) Where the terrain information is displayed on a multi-function display, failure of the TAWS does not prevent the normal functioning of other systems using that display.
