Background: AC 23.1311-1B, “Installation of Electronic Displays in Part 23 Airplanes,” will replace AC 23.1311-1A, “Installation of Electronic Display Instrument Systems in Part 23 Airplanes,” dated March 12, 1999.

Amendment 23-41, effective November 26, 1990, established airworthiness standards under § 23.1311 for installing electronic display instrument systems in normal, utility, acrobatic, and commuter category airplanes. When the first electronic displays were developed, they replaced conventional electromechanical components. Later designs provided more extensive information integration. Amendment 23-49, effective March 11, 1996, harmonized 14 CFR, part 23, with the Joint Aviation Requirements. The most recent revision to § 23.1311 removed redundant requirements and clarified what secondary instruments are required.
