-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of and requests

and guidance concerning an acceptable means, but not the only means, of

part 23, applicable to the installation of electronic displays in part 
23 airplanes. This AC contains over twenty updates since the last 
issuance. Two of the major revisions are new sections: field-of-view

    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 Sec.  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 Sec.  23.1311 
removed redundant requirements and clarified what secondary instruments 
are required.

    Issued in Kansas City, Missouri on June 16, 2004.
William J. Timberlake,
Acting Manager, Small Airplane Directorate, Aircraft Certification 
Service.
