AWO.B.CATIII.105 CS AWO.B.CATIII.105 Control of flight path and ground roll

- (a) Landing systems, other than HUDLS, shall control the aeroplane within the prescribed limits along the flight path to touchdown (see CS AWO.B.CATIII.115(a) and (b)) and along the runway (see CS AWO.B.CATIII.117) when appropriate, and specifically: - (1) For fail-passive automatic landings, the primary mode of controlling the aeroplane shall be automatic until the main wheels touch the ground (except as in CS AWO.B.CATIII.113(b)(1)), and for operation with no DH, the control shall be automatic until the nose wheels touch down. - (2) For DHs below 15 m (50 ft), a fail-operational landing system (automatic or hybrid) shall be provided which, when appropriate, includes provision for the control of the aeroplane along the runway during the ground roll down to a safe speed for taxiing. - (3) If the landing roll-out is to be accomplished automatically using rudder control, the rudder axis shall be engaged during the approach phase.

Easy Access Rules for All-Weather Operations (CS-AWO)

- (b) For HUDLs, the following applies: - (1) The system shall provide sufficient guidance information to enable a pilot that is competent to conduct the intended operation to intercept the xLS approach path, if that capability is provided, to track it, to land the aeroplane within the prescribed limits or to perform a go-around without reference to other cockpit displays. It shall not require exceptional piloting skill to achieve the required performance. (See CS AWO.B.CATIII.115(a) and (b)) - (2) If the autopilot is used to control the flight path of the aeroplane to intercept and establish the xLS approach path, the point during the approach at which the transition from automatic to manual flight takes place shall be identified and taken into account in the performance demonstration (see CS AWO.B.CATIII.115).
