Denti – 737 CatIIIb?
How is this achieved with two fail passive autopilots, or is the aircraft fitted with HUD enabling a ‘hybrid’ operation?
Is it possible that the aircraft certification (CS AWO) is for CatIIIa using a 50 ft DH, but the operational approval (EASA Ops 1 – JAR OPS 1) enables a non standard – extended operation in RVRs less than normally accepted for CatIIIa?
