AMC11 CAT.OP.MPA.110 Aerodrome operating minima ED Decision 2023/007/R EFFECT ON LANDING MINIMA OF TEMPORARILY FAILED OR DOWNGRADED GROUND EQUIPMENT (a) General These instructions are intended for use both before and during flight. Only those facilities mentioned in Table 17 should be acceptable to be used to determine the effect of temporarily failed of downgraded equipment. It is, however, not expected that the commander would consult such instructions after passing 1 000 ft above the aerodrome. If failures of ground aids are announced at such a late stage, the approach could be continued at the commander’s discretion. If failures are announced before such a late stage in the approach, their effect on the approach should be considered as described in Table 17, and the approach may have to be abandoned. (b) Conditions applicable to Table 17: (1) multiple failures of runway/FATO lights other than those indicated in Table 17 should not be acceptable; (2) failures of approach and runway/FATO lights are acceptable at the same time, and the most demanding consequence should be applied; and (3) failures other than ILS, GLS, MLS affect the RVR only and not DH.
