RTCA DO-374

This document is the minimum operational, safety, and performance requirements (SPR) and interoperability requirements (INTEROP) for Enhanced Flight Vision System (EFVS) associated with recommended takeoff minima.

Takeoff minima are established for the use of vision systems technologies, treated as subsystems, which together with other subsystems including navigational aids and airport lighting and markings, are used to accomplish the operational goal, achieve levels of reliability, availability, and integrity appropriate to the intended function and phase of flight. These levels are consistent with other systems and subsystems used for the same intended function and phase of flight.
