DEPARTMENT OF TRANSPORTATION
Airborne Weather Radar With Forward-Looking Windshear Capability
AGENCY: Federal Aviation Administration.
ACTION: Notice of availability for public comment.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of and request comments
on a proposed technical standard order (TSO) pertaining to airborne
weather radar with forward-looking windshear capability. The proposed
TSO prescribes the minimum performance standards that airborne weather
radar with forward-looking windshear capability must meet to be
identified with the marking ``TSO-C134.''
DATES: Comments must identify the TSO file number and be received on or
before July 20, 1995.
ADDRESSES: Send all comments on the proposed technical standard order
to: Technical Program and Continued Airworthiness Branch, AIR-120,
Aircraft Engineering Division, Aircraft Certification Service--File No.
TSO-C134, Federal Aviation Administration, 800 Independence Avenue,
SW., Washington, DC 20591. Or deliver comments to: Federal Aviation
Administration, Room 804, 800 Independence Avenue, SW., Washington, DC
20591.
FOR FURTHER INFORMATION CONTACT:
Ms. Bobbie J. Smith, Technical Program and Continued Airworthiness
Branch, AIR-120, Aircraft Engineering Division, Aircraft Certification
Service, Federal Aviation Administration, 800 Independence Avenue, SW.,
Washington, DC 20591, Telephone (202) 267-9546.
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 technical standard order may be examined,
before and after the comment closing date, in Room 804, 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 is a new TSO that sets forth minimum operational performance
standards for airborne weather radar with forward-looking windshear
detection capability.
For windshear detection, the airborne radar equipment must detect
areas containing windshear activity. It must be capable of correlating
and generating appropriate alerts based on F factor. This output must
be clear, automatic, concise and distinct to allow for rapid pilot
interpretation. The selection of the windshear detection mode must be
done automatically during takeoff and landing phases of flight.
This TSO contains standards for weather detection and ground
mapping. In the case of weather detection, the airborne radar equipment
must detect and display echoes from precipitation in a way that will
allow flight crew analysis of probable turbulent areas ahead. In the
case of ground mapping, the airborne radar equipment must be able to
detect and display echoes from the surface of the earth to allow in-
flight analysis.
How to Obtain Copies
A copy of the proposed TSO-C134 may be obtained by contacting For
Further Information Contact. Copies of RTCA Document No. DO-220,
``Minimum Operational Performance Standards for Airborne Weather Radar
with Forward-Looking Windshear Capability,'' may be purchased from the
RTCA Inc., 1140 Connecticut Avenue, NW., Suite 1020, Washington, DC
20036.
Issued in Washington, DC, on April 12, 1995.
