3. Technical Standard Orders (TSO)

You may obtain a copy of the current edition of the following publications from the Federal Aviation Administration; Aircraft Certification Service; Aircraft Engineering Division;

Technical and Administrative Support Staff Branch, AIR-103; 800 Independence Avenue, SW;

Washington, DC 20591 or at the FAA website: www.faa.gov. The following is a partial list of the FAA TSOs that may relate to electronic displays. For a complete list of TSOs, see AC 20-110, “Index of Aviation Technical Standards Orders.” It should be noted applicants might apply for a TSO that does not adequately address all of the functionality in the system.

Applicants may also apply for multiple TSOs, since no single TSO applies to all functions.

Installers of equipment manufactured using the TSO process should ensure that the equipment was tested in an environment similar to the environment where the equipment will be installed.
