IR Implementing rule

## AWO.A.EFVS.110 CS AWO.A.EFVS.110 Enhanced flight vision system -landing (EFVS-L) -Landing performance

\- (a) The lateral and longitudinal touchdown performance of an EFVS-L system shall be demonstrated and shall be equivalent to or better than that normally achieved in visual operations. The use of the EFVS-L system must provide acceptable performance in all conditions for which it is intended to be used.

\- (b) If EFVS-L flare cue results in an increase to the landing distance, then the appropriate increment shall be established and scheduled in the AFM.

\- (c) The image/symbology of an EFVS-L system shall provide the visual cues for the pilot to perform the following without requiring exceptional piloting skill, alerting, strength or excessive workload:

\- (1) control of approach speed (manual or automatic) up to the point of landing;

\- (2) transition through flare to landing;

\- (3) approach, flare, and landing at a normal sink rate for the aircraft;

\- (4) prompt and predictable correction of any lateral deviation away from the runway centre line to smoothly intercept the centre line;

\- (5) touchdowns with a bank angle that is not hazardous to the aeroplane;

\- (6) a normal derotation;

\- (7) control of the path of the aeroplane along the runway centre line through roll-out to a safe taxi speed; and

\- (8) a safe go-around any time, including up to touchdown in all configurations to be certified.

AMC Acceptable means of compliance

## AMC1 AWO.A.EFVS.110 EFVS-L landing performance

\- (a) Due to the fact that a flare cue is required for EFVS-L operations, the landing distance to be applied for EFVS-L operations should be the landing distance established for the flare cue (see AMC AWO.A.HUD.112).

\- (b) During all EFVS-L tests, the acceptable landing criteria should be achieved and demonstrated in accordance with the criteria of AMC2 AWO.A.EFVS.110.

AMC Acceptable means of compliance

## AMC2 AWO.A.EFVS.110 Acceptable landing performance criteria for EFVS-Ls

\- (a) The landing performance of an EFVS-L is acceptable if the EFVS-L image/symbology provides the pilot with visual cues to enable to perform the following without requiring exceptional piloting skill or alertness:

\- (1) Speed control within +10/ -5 kt of the approach speed, whether manually controlled or with auto-throttle, as proposed by the applicant, up to the point where the throttles are retarded for landing.

\- (2) A smooth transition through flare to landing.

\- (3) Approach, flare, and landing at a normal sink rate for the aircraft, i.e. the average touchdown rate of descent not exceeding 6 ft per second.

\- (4) All touchdowns in the TDZ. Longitudinal touchdown performance should be demonstrated within the TDZ which is the first one third, or the first 3 000 ft, of the usable runway, whichever is more restrictive, and demonstrated to be equivalent to or better than that achieved in visual operations for the specific aircraft.

\- (5) Prompt and predictable correction of any lateral deviation away from the runway centre line to smoothly intercept the centre line.

\- (6) Touchdowns with a bank angle that is not hazardous to the aeroplane, i.e. no contact of any part of the engine nacelle or the wing with the ground.

\- (7) A normal derotation.

\- (8) Satisfactory and smooth control of the aeroplane from touchdown to a safe taxi speed.

\- (9) Satisfactory and smooth control of the path of the aeroplane along the runway centre line through roll-out to a safe taxi speed.

\- (10) A safe go-around any time, including up to touchdown in all configurations to be certified.

\- (b) The demonstrated performance of the installed EFVS-L at representative visibility levels for EFVS landing system operations will determine whether there is a need for any additional limitations (for example, crosswind and offset). Appropriate limitations should be published in the AFM.
