Comments Invited: We invite interested parties to submit comments on the proposed AC. Commenters must identify AC 23.1311-1B and submit comments to the address specified above. The FAA will consider all communications received on or before the closing date for comments before issuing the final AC.

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.

Issued in Kansas City, Missouri on June 16, 2004.

Acting Manager, Small Airplane Directorate, Aircraft Certification Service.
