Date Issued: December 06, 2016
Responsible Office: AIR-130, Aviation Safety - Aircraft Certification Service, Aircraft Engineering Division
Description: This advisory circular (AC) provides guidance for gaining airworthiness approval for enhanced and synthetic vision systems in aircraft. Specifically, it provides one acceptable means for complying with Title 14 of the Code of Federal Regulations (14 CFR) part 23, 25, 27, or 29 airworthiness regulations when installing a synthetic vision system (SVS), enhanced vision system (EVS), combined vision system (CVS), or enhanced flight vision system (EFVS) in an airplane or rotorcraft. Since the release of Draft AC 20-167A for public comment, the FAA revised the standard format for Advisory Circulars. AC 20-167A is formatted in compliance with the new standard format, meaning the numbering of paragraphs changed from the draft that was presented for public comment. The preamble accompanying the 2016 EFVS rule specifically references paragraphs 4-5, 4-5.c.4, 4-5.c.4.(h).(iv), and 6-2.f.4. These referenced paragraphs equate to paragraphs 4.5, 4.5.3.4, 4.5.3.4.8.4, 6.2.6.4, respectively.
