• ED Decision 2012/019/R found in: Air Operations (965/2012) Part-ARO Part-ORO Part-CAT Part-SPA Part-NCC Part-NCO Part-SPO (Sep 2023)

AMC1 SPA.NVIS.110(b) Equipment requirements for NVIS operations ED Decision 2012/019/R RADIO ALTIMETER (a) The radio altimeter should: (1) be of an analogue type display presentation that requires minimal interpretation for both an instantaneous impression of absolute height and rate of change of height; (2) be positioned to be instantly visible and discernable from each cockpit crew station; (3) have an integral audio and visual low height warning that operates at a height selectable by the pilot; and (4) provide unambiguous warning to the crew of radio altimeter failure. (b) The visual warning should provide: (1) clear visual warning at each cockpit crew station of height below the pilot-selectable height; and (2) adequate attention-getting-capability for typical NVIS operations. (c) The audio warning should: (1) be unambiguous and readily cancellable; (2) not extinguish any visual low height warnings when cancelled; and (3) operate at the same pilot-selectable height as the visual warning.
