PURPOSE OF THIS DOCUMENT

This document defines and allocates the set of minimum requirements for the end-toend operational, safety, performance, and interoperability aspects for implementations of EFVS takeoff with recommended minima.

Allocation of these requirements is done by this SPR/INTEROP to the necessary domains of the aircraft with dependencies and assumptions, if necessary, to the airport operations, air navigation services providers (ANSP), and infrastructure level.

These requirements are intended to be used for approval processes including aircraft type design approval, aircraft operator operational approval, and (should they be necessary) Air Traffic Services (ATS) provider operational approval. Chapter 1.1.3 below provides more information on the use of this document for approvals.

In addition, this document provides guidance to determine the levels of design assurance and performance that are needed for each element (aircraft, operator, and, if applicable, ANSP—Air Navigation Service Provider and airport infra-structure level) to support the application.
