ED Decision 2022/007/R

- (a) The mode of operation (display status (e.g. displayed/not displayed)) and any mode that could have an impact on the EFVS performance (e.g. level of contrast or resolution of the image) shall be: - (1) annunciated on the flight deck; - (2) visible to the flight crew; and - (3) recorded by the flight data recorder if required to be installed. - (b) Any detected EFVS malfunction that can adversely affect the normal operation of the EFVS shall be annunciated to the flight crew and shall include as a minimum sensor failures and frozen image failure messages. - (c) No single EFVS malfunction shall lead to the display of misleading information leading to a Hazardous or Catastrophic failure condition. Detected malfunctions shall be annunciated and the malfunctioning display elements removed.

Show the text

The following minimum information should be provided in the AFM:

- (a) the approved limits established as a result of consideration of any other factor that the certification has shown to be appropriate; - (b) the normal and abnormal procedures, including airspeeds; - (c) the minimum required equipment; - (d) any additional aeroplane performance limitations; - (e) if appropriate, the type of approaches and the xLS navigation means (facilities external to the aircraft) and associated limitations (if any) which have been used as the basis for certification; - (f) any related limitations and/or assumptions on the runway or aerodrome conditions that are affected by the use of the EFVS; for EFVS-L, this should also consider: - (1) runway elevation, - (2) approach path slope, - (3) touchdown zone slope, - (4) ground profile under the approach path; - (g) the type and mode of operation/configuration of the approach lights (i.e. LED or incandescent) that have been used or assumed during the certification demonstration of the EFVS; - (h) the demonstrated performance in accordance with CS AWO.A.EFVS.109; - (i) wind speed limitations that are affected by the use of the EFVS; - (j) any applicable assumptions that have been made during the certification demonstration of the EFVS.
