This document provides the high level system requirements for EFVS when installed in aircraft with the express purpose of enabling specified straight-in instrument approaches with published vertical guidance to touchdown, landing, and roll-out to a safe taxi speed in visibility as low as 300 ft RVR (100 m) by use of an approved EFVS without need or reliance on natural vision. This MASPS follows from and expands upon the concepts and requirements established under DO-315A and the precedents established under 14 CFR §91.175 (l) and (m), which identified performance standards for an enhanced flight vision systems (EFVS) to enable approach, landing, roll-out and taxi, down to 1000 ft (300 m) runway visual range (RVR).

The operational concept follows a fail-operational design. The operational scenarios used for design context and concepts discussed in this document are written to describe the intended use of the proposed systems and from this context, associated minimum performance standards are derived. They do not define current or future operational regulations or limitations of these technologies.
