The solution addresses Enhanced Flight Vision System (EFVS) to land operations supported by IR and Visual based technology. The solution allows the pilot to descent below DA/DH and perform landing in RVR as low as 300m (without the need for transition to natural vision) taking credit of an EFVS system.

The EFVS system is composed of a Head Up system (or equivalent HWD) and a multispectral camera providing the capability to see in advance compared to naked eye in degraded weather conditions. This capacity of EFVS operation to provide a significant visual advantage in conditions such as fog or snow at DA/DH will enable a successful landing, which would be not possible otherwise. This EFVS advanced operation concept differs from other standard CAT II/III concepts (usually available at main airports and used by airlines) as it allows operating in comparable weather adverse conditions, but at far many small medium airports than just a few numbers of fully CATII/III equipped airports.

The strength of EFVS with operational credit concept proposed is to take benefit of an advanced aircraft capacity based on technology rather than requiring heavy and costly aerodrome infrastructures.

EFVS operation is applicable and adds credit to most of 3D instrument approaches. The solution can be deployed in the near future thanks to the new EU AWO regulation resulting from EASA NPA AWO 2018-06, and some aircraft manufacturers have already been certified by EASA through CRI process.

Note: based on the regulation publication date, the initial operational capability (IOC) is targeted in 2023.
