as a Means for Air Traffic Services Communications

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability and requests for public comment.

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

SUMMARY: This notice announces the availability of and requests 
comments on a proposed Advisory Circular (AC) 20-SV, Satellite Voice 
Equipment as a Means for Air Traffic Services Communications. This 
proposed AC provides guidance for designers, manufacturers, and 
installers of satellite voice equipment used for Air Traffic Services. 
In it, we recommend how you get design and airworthiness approval for 
your equipment.

DATES: Comments must be received on or before August 2, 2004.

ADDRESSES: Send all comments on the proposed AC to: Federal Aviation 
Administration (FAA), Aircraft Certification Service, Aircraft 
Engineering Division, Avionic Systems Branch, AIR-130, 800 Independence

Background

    Aircraft operators have traditionally used High Frequency (HF)/Very 
High Frequency (VHF) communications systems for Aeronautical 
Operational Control and Air Traffic Services operations. Due to 
frequency congestion in oceanic and remote flight operations, aircraft 
operators have requested the use of satellite voice communication 
systems as a supplement to existing HF and VHF voice systems. Therefore 
the objective of this proposed AC is to provide guidance to allow for 
the airworthiness certification and evolutionary development of 
satellite voice during flight operations without compromising safety.

How To Obtain Copies

    You may get a copy of the proposed AC from the Internet at http://www.airweb.faa.gov/rgl. Once on the RGL Web site, select ``Advisory 
Circular'', then select the document by number. See section entitled 
For Further Information Contact for the complete address if requesting 
a copy by mail.

Assistant Manager, Aircraft Engineering Division, Aircraft 
Certification Service.
