Notice of availability and requests for public comment.

SUMMARY:

This notice announces the availability of and requests comments on a proposed Technical Standard Order (TSO)-C166, Extended Squitter Automatic Dependent Surveillance—Broadcast (ADS-B) and Traffic Information Service—Broadcast (TIS-B) Equipment Operating on the Radio Frequency of 1090 Megahertz (MHz). This proposed TSO tells persons seeking a TSO authorization or letter of design approval what minimum performance standards (MPS) their Extended Squitter ADS-B and TIS-B equipment must meet to be identified with the applicable TSO marking.

DATES:

Comments must identify the TSO file number and be received on or before September 15, 2003.

ADDRESSES:

Send all comments on the proposed technical standard order to: Federal Aviation Administration (FAA), Aircraft Certification Service, Aircraft Engineering Division, Avionic Systems Branch, AIR-130, File No. TSO-C166, 800 Independence Avenue, SW., Washington, DC 20591.

SUPPLEMENTARY INFORMATION:

Comments Invited

Interested persons are invited to comment on the proposed TSO listed in this notice by submitting such written data, views, or arguments as they desire to the above specified address. Comments received on the proposed TSO may be examined, before and after the comment closing date, in Room 815, FAA Headquarters Building, 800 Independence Avenue, SW., Washington, DC 20591, weekdays except Federal holidays, between 8:30 a.m. and 4:30 p.m. All communications received on or before the closing date for comments specified above will be considered by the Director of the Aircraft Certification Service before issuing the final TSO.

Background

This proposed TSO prescribes the MPS for airborne equipment to support Automatic Dependent Surveillance—Broadcast (ADS-B) using Extended Squitter equipment operating on the frequency of 1090 MHz. ADS-B is a system by which aircraft and certain equipped surface vehicles can share position, velocity, and other information with one another, and with ground-based facilities such as air traffic services via radio broadcast techniques. Extended Squitter ADS-B will also support the reception of Traffic Information Service—Broadcast (TIS-B) messages. Two major classes of 1090 MHz Extended Squitter ADS-B equipment are supported by this proposed TSO; Class A() equipment which incorporates both a broadcast and received subsystem, and Class B() equipment which supports broadcast only.
