AWO.A.HUD.104 CS AWO.A.HUD.104 Control of take-off roll, flight path and ground roll

(a)Head-up display landing system (HUDLS)

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.SACATI.113 or CS AWO.B.CATII.113 or CS AWO.B.CATIII.115(a) and (b) or CS AWO.B.CATIII.117)

(b)The transition from approach/flare guidance to roll-out control guidance shall be smooth and shall not distract the pilot from performing the intended operation.

(c)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). The transition from autopilot to head-up guidance shall not require exceptional piloting skill, alertness, strength or excessive workload.

(d)For take-off roll, the HUD (or equivalent display) shall meet the performance requirements of CS AWO.C.TOO.106.

(e)The HUD characteristics and dynamics shall be suitable for the manual control of the aircraft.
