## AWO.B.CATIII.116 CS AWO.B.CATIII.116 Head-up display fail-operational hybrid landing system

Where a HUDLS is fitted as part of a hybrid system, its performance need not meet the same criteria as the primary system provided that it:

(a) meets the overall performance requirements, taking into account the probability that it will be used; and

(b) is sufficiently compatible with the primary system so as to retain pilot confidence.
