Description
Establishes an acceptable means, but not the only means, of obtaining FAA airworthiness approval for the installation of a TAWS that has been approved under Technical Standard Order (TSO)-C151A, Terrain Awareness and Warning System, in a Part 23 airplane. The FAA’s TSO process is a means for obtaining FAA design and performance approval for an appliance, system, or product; however, the TSO does not provide installation approval. This AC serves to provide guidance for designing an acceptable installation for a TAWS that complies with TSO-C151a. The guidance provided is specific to installations of these systems on airplanes certificated under Title 14 of the Code of Federal Regulations Part 23. It describes the airworthiness considerations for such installations as they apply to the unique features of the TAWS and the interface of the TAWS with other systems on the airplane.
