Background

On November 29, 1999, the FAA issued TSO-C151a. TSO-C151a prescribes the minimum design standards that a TAWS must meet to be identified with the TSO-C151a marking. For further in-depth information concerning the TAWS' capabilities, refer to TSO-C151a.

The FAA's TSO process is a means of obtaining FAA design and performance approval for an appliance, system, or product. However, the TSO does not provide procedures for installation approval or procedures for design or implementation of an installation. With future rulemaking and heightened interest by manufacturers and operators to equip Part 23 airplanes with TAWS systems that are compliant with TSO-C151a, the FAA has recognized the need to establish guidance material for the design and test requirements for the installation of such systems. This AC has been developed as the means for providing such guidance for Part 23 airplanes.

Issued in Kansas City, Missouri, on January 19, 2000.

Manager, Small Airplane Directorate.
