Aircraft Earth Station Equipment

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability and requests for public comment.

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

SUMMARY: This announces the availability of and request comments on a 
proposed Technical Standard Order (TSO) C-132, Geosynchronous Orbit 
Aeronautical Mobile Satellite Services Aircraft Earth Station 
Equipment. The proposed TSO tells manufacturers seeking TSO 
authorization or letter of design approval what minimum performance 
standard (MPS) their equipment must first meet to obtain approval and 
identification with the applicable TSO markings.

DATES: Comments must identify the TSO and arrive by January 30, 2004.

ADDRESSES: Send all comments on the proposed TSO to: Federal Aviation 
Administration, Aircraft Certification Service, Aircraft Engineering 
Division, Avionic Systems Branch, Room 815, 800 Independence Avenue, 
SW., Washington, DC 20591. Attn. Mr. Albert Sayadian, AIR-130. Or, 
deliver comments to: Federal Aviation Administration, Room 815, 800 
Independence Avenue, SW., Washington, DC 20591.

SUPPLEMENTARY INFORMATION:

Comments Invited

    You may comment on the proposed TSO listed in this notice by 
sending such written data, views, or arguments to the above listed 
address. You may also examine comments received on the proposed TSO, 
before and after the comment closing date, in Room 815, FAA

all communications received by the closing date before issuing the 
final TSO.

Background

    This proposed TSO applies to Aeronautical Mobile Satellite Services 
(AMSS) Aircraft Earth Station (AES) equipment that provides direct 
worldwide communications between aircraft subnetworks and ground sub 
networks via aeronautical mobile satellites and their ground earth 
stations. Note that the capability of the AMSS includes the support of 
both data and voice communications between aircraft and ground-based 
users. To accomplish this task, the MPS contained in the proposed TSO-
C132 will assist manufacturers of geosynchronous orbit AMSS AES 
articles in their compliance with the applicable requirements of RTCA 
Document Number (RTCA/DO) 210D, Minimum Operational Performance 
Standards (MOPS) for Geosynchronous Orbit Aeronautical Mobile Satellite 
Services Avionics, dated April 19, 2000.

How To Get Copies

    You may get a copy of the proposed TSO via the Internet at, http://www.faa.gov/certification/aircraft/TSOA.htm, or by contacting the 
person listed in the section titled FOR FURTHER INFORMATION CONTACT.

    Issued in Washington, DC, on December 19, 2003.
