This document addresses Enhanced Vision Systems (EVS), Synthetic Vision Systems (SVS) and Combined Vision Systems (CVS) technologies. DO-315B adds system design criteria for use of SVS for lower-than-standard Category I ILS minima. Specific features include SVS with system performance, database, alerts, pilot controls, display and symbology requirements. Respective flight test and rationale appendices were added.
For the FAA, EVS for operational credit is called an Enhanced Flight Vision System (EFVS), and the term "EFVS" is used in this document. The EFVS subsections of this MASPS provide the high-level system requirements for Enhanced Flight Vision Systems when installed in aircraft with the express purpose of gaining additional operational credit under FAA Order 8400.13. EFVS performance requirements were not changed but updates are planned for in future revisions.
The European Aviation Safety Agency (EASA) uses the term "EVS" as equivalent to the FAA description of EFVS.View Less
