AWO.A.EFVS.102 CS AWO.A.EFVS.102 Enhanced flight vision system designation

- (a) An enhanced flight vision system -approach (EFVS-Approach (EFVS-A)) is a system that has been demonstrated to meet the criteria to be used for approach operations from a DA/H or an MDA to 30 m (100 ft) touchdown zone elevation (TDZE) whilst all system components function as intended, but may have failure modes that could result in the loss of the EFVS capability. It shall be assumed for an EFVS-A that: - (1) the pilot will conduct a go-around above 30 m (100 ft) TDZE, in the event of an EFVS failure; and - (2) descent below 30 m (100 ft) above the TDZE through to touchdown and roll-out shall be conducted using natural vision in order that any failure of the EFVS shall not prevent the pilot from completing the approach and landing. - (b) An enhanced flight vision system -landing (EFVS-Landing (EFVS-L)) is a system that has been demonstrated to meet the criteria to be used for approach and landing operations that rely on sufficient visibility conditions to enable unaided roll-out and to mitigate for the loss of the EFVS function.

Note: When a HUD (or equivalent display) is used for an EFVS-L, it does not necessarily have to comply with the HUDLS requirements.

- (c) An EFVS that meets the certification criteria for an EFVS-L shall be considered to have met the certification criteria for an EFVS-A.
