DEPARTMENT OF TRANSPORTATION

Airborne Area Navigation Equipment Using Multi-Sensor Inputs

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of availability.

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

SUMMARY: This notice announces the availability of and requests 
comments on a proposed technical standard order (TSO) pertaining to 
airborne area navigation equipment using multi-sensor inputs. The 
proposed TSO prescribes the minimum performance standards that airborne 
area navigation equipment using multi-sensor inputs must meet to be 
identified with the marking ``TSO-C115b.''

DATES: Comments must be received on or before April 19, 1994.

ADDRESSES: Send all comments on the proposed technical standard order 
to: Technical Analysis Branch, AIR-120, Aircraft Engineering Division 
Aircraft Certification Service--File No. TSO-C115b, Federal Aviation 
Administration, 800 Independence Avenue, SW., Washington, DC 20591. Or 
deliver comments to: Federal Aviation Administration, room 335, 800 
Independence Avenue, SW., Washington, DC 20591.

FOR FURTHER INFORMATION CONTACT:
Ms. Bobbie J. Smith, Technical Analysis Branch, AIR-120, Aircraft 
Engineering Division, Aircraft Certification Service, Federal Aviation 
Administration, 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 must 
identify the TSO file number. Comments received on the proposed 
technical standard order may be examined, before and after the comment 
closing date, in room 335, FAA Headquarters Building (FOB-10A), 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 Technical Standard Order (TSO) is being revised to incorporate 
standards for Global Positioning System (GPS) technology into the 
standards for multi-sensor navigation systems. In December 1992, TSO-
C129 was issued to provide minimum operational standards for GPS 
navigation equipment. This TSO established requirements on multi-sensor 
equipment that uses GPS as a navigation source. This revision to TSO-
C115a incorporates those criteria in the multi-sensor standard. No new 
criteria have been established by these changes. This revision 
incorporates only previously published standards into this TSO.

How to Obtain Copies

    A copy of the proposed TSO-C115b may be obtained by contacting 
``For Further Information Contact.'' Copies of RTCA Document No. DO-
187, ``Minimum Operational Performance Standards for Airborne Area 
Navigation Equipment Using Multi-Sensor Inputs,'' may be purchased from 
RTCA, Inc., 1140 Connecticut Avenue, NW., suite 1020, Washington, DC 
20036.

    Issued in Washington, DC, on February 22, 1994.

Manager, Aircraft Engineering Division, Aircraft Certification Service.
