Operators without a “radio altimeter tolerant airplane” are prohibited from conducting EFVS operations to touchdown and rollout under § 91.176(a) at airports in the 48 contiguous U.S. Operators should consult their aircraft OEM for information regarding their aircraft’s “radio altimeter tolerant” status. More information can be found in Airworthiness Directive 2023-10-02.
