**Technical Standard Order (TSO)-C68a, Airborne Automatic Dead Reckoning**  **Computer Equipment Utilizing Aircraft Heading and Doppler Ground Speed**  **and Drift Angle Data (for Air Carrier Aircraft)** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of intent to cancel Technical Standard Order (TSO)-C68a, Airborne automatic dead reckoning computer equipment utilizing aircraft heading and Doppler ground speed and drift angle data (for air carrier aircraft).

**SUMMARY :**  This notice announces the FAA’s intent to cancel TSO-C68a, Airborne automatic dead reckoning computer equipment utilizing aircraft heading and Doppler ground speed and drift angle data. The effect of the cancelled TSO–68a will result in no new TSO-C68a design or production approvals.

**DATES :**  Comments must be received on or before July 23, 2012.

**FOR FURTHER INFORMATION CONTACT :**  Mr. Albert Sayadian, AIR–130, Federal Aviation Administration, 470 L’Enfant Plaza, Suite 4102, Washington, DC 20024. Telephone (202) 385–4652, fax (202) 385–4651, email to: albert.sayadian@faa.gov.

Comments Invited

You are invited to comment on the cancellation of the TSO-C68a by submitting written data, views, or arguments to the above address. Comments received may be examined, both before and after the closing date at the above address, weekdays except Federal holidays, between 8:30 a.m. and 4:30 p.m. The Director, Aircraft Certification Service, will consider all comments received on or before the closing date. Background

Doppler radar is a semiautomatic selfcontained dead reckoning navigation system (radar sensor plus computer) which is not continuously dependent on information derived from ground based or external aids. The system employs radar signals to detect and measure ground speed and drift angle, using the aircraft compass system as its directional reference. Doppler is less accurate than Inertial Navigation System (INS), however, and the use of an external reference is required for periodic updates if acceptable position

accuracy is to be achieved on long range flights. Use of INS and Global Positioning System (GPS) has rendered TSO-C68a systems obsolete. The FAA has no record of any applications for TSO-C68a since it was published in 1983. Given the obsolescence of the equipment and the lack of industry interest in TSO-C68a product designs, we propose cancelling TSO-C68a.

**Technical Standard Order (TSO) C-122a, Equipment That Prevent**  **Blocked Channels Used in Two-Way Radio Communications Due to**  **Simultaneous Transmissions**

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice.

**SUMMARY :**  This notice announces the FAA’s intent to cancel TSO-C122a, Equipment That Prevent Blocked Channels Used in Two-Way Radio Communications Due to Simultaneous Transmissions. The effect of the cancelled TSO will not affect design or production according to an existing TSO authorization (TSOA). Articles produced under an existing TSOA can still be installed according to existing airworthiness approvals and applications for new airworthiness installation approvals will still be processed.

**DATES :**  Comments must be received on or before July 23, 2012.

**SUPPLEMENTARY INFORMATION :** 
Comments Invited

You are invited to comment on the proposed cancellation of the TSO by submitting written data, views, or arguments to the above address. Comments received may be examined, both before and after the closing date at the above address, weekdays except federal holidays, between 8:30 a.m. and 4:30 p.m. The Director, Aircraft Certification Service, will consider all comments received on or before the closing date. Background

In 1984, the FAA was petitioned to enact rulemaking requiring two-way radio communication systems employing anti-blocking and stuck microphone protection circuitry. Our response to this rulemaking petition was the issuance of TSO-C128, Devices thatPrevent Blocked Channels Used in TwoWay Radio Communications Due to Unintentional Transmissions, for preventing blocked channels used in two-way radio communication due to unintentional transmissions. TSO-C128, and the subsequent revision, has proven effective and popular with VHF radio manufacturers. Since 1994, there has been only one application for TSOA for TSO-C122a. Therefore, we believe it is appropriate to cancel TSO-C122a, given the eventual obsolescence of TSO-C122a equipment and the lack of industry interest in new TSO-C122a product designs. We continue to coordinate with industry’s federal advisory committee through RTCA Special Committee (SC) 226, Audio Systems and Equipment, for any new developments on other means being used to address blocked channels caused by simultaneous transmissions.
