Draft Technical Standard Orders Open for Comment

REFERENCE: Draft Technical Standard Orders (TSOs) C 129b Open for Comment

SUMMARY: “Minimum Operational Performance Standards for Un-Augmented GPS Used for Supplemental Navigation:” DO-316 is available for final comment and review at RTCA. This standard is based on DO-229D, minus the SBAS requirements for new GPS equipment not augmented by ground or space-based systems. This standard and future TSO will replace DO-208/TSO-C129a.

MAJOR HIGHLIGHTS: The Avionics Systems Branch of the Aircraft Engineering Division, Aircraft Certification Service, Federal Aviation Administration, is in the process of developing a new technical standard order (TSO) for L1 C/A code un-augmented GPS.

RTCA Inc., Special Committee (SC)-159, is developing RTCA Document DO-316, “Minimum Operational Performance Standards for Un-Augmented GPS Used for Supplemental Navigation,” which will become the minimum performance standard (MPS) for the proposed new TSO.

The purpose of this notice is to make the public aware the document developed by SC-159 is now available for final review and comment, prior to presentation to the full SC-159 plenary for review and approval.

The RTCA comment period closes Feb. 6, 2009. To comment on this proposed RTCA document or for a copy of the final review and comment document and appropriate comment forms and instructions, contact Hal Moses of RTCA at 202-833-9339 or by e-mail at: hmoses@rtca.org.

Note: Do not submit comments to the FAA. All comments must be submitted to RTCA for appropriate disposition by the special committee.

The proposed revised TSO-C129b will be available for public review once RTCA Document DO-316 is approved by the RTCA Program Management Committee. If you have questions regarding this notice-of-intent, contact Kevin Bridges at 202-385-4627 or by e-mail at kevin.bridges@faa.gov
