  • DO-390 - Test Procedures for Quantified Visual Advantage
  • This document provides a consensus standard for a method to measure and quantify the visual advantage performance of an installed Enhanced Flight Vision System (EFVS). In 2016 the FAA published revised EFVS-related regulations that expanded the types of approved EFVS operations and the number of operators that could use the new EFVS regulations. While, demonstrating a quantified visual advantage is not required for an installed EFVS to be certified, any operator that uses the installed EFVS to dispatch the aircraft in accordance with 14 CFR §121.613, §125.361, or §135.219 or commence an instrument approach under §121.561, §125,325, §125.381, or §135.225 requires an operational approval from FAA flight standards. In the European Union (EU), the requirement to demonstrate a visual advantage using an EFVS is introduced through the NPA 2018-06 subpart B which includes the proposed amendments to CS-AWO (airworthiness requirements). For the EFVS operator to be granted certain operational approvals, the applicant must demonstrate and document a quantifiable measure of the EFVS visual advantage performance. This document provides a consensus standard for a method via flight test to measure and quantify the visual advantage performance of an installed Enhanced Flight Vision System (EFVS). This document has been developed with EUROCAE Working Group 79 (WG-79) and is technically equivalent to ED-291.
