VZI00220AVIATION SERVICES TRANSPONDER TRANSMITTER

TT31 Mode S Transponder Operating Manual 00454-00-AA 1 September 2006 Trig Avionics Limited Heriot Watt Research Park Riccarton, Currie EH14 4AP Scotland, UK © Copyright 2006 Front Panel Display The display shows the operating mode of the transponder, the reported pressure altitude, and the current squawk code and Flight ID. The reply indicator is active when the transponder replies to interrogations. The pressure altitude is displayed as a Flight Level, which is the pressure altitude in hundreds of feet. When non-standard atmospheric conditions apply, this may not match the altimeter indicated altitude, but will be correctly displayed by the ATC radar. Mode Selector Knob The left hand knob controls the power to the transponder and the operating mode. OFF Power is removed from the transponder. SBY The transponder is on, but will not reply to any interrogations. GND The transponder will respond to Mode S ground interrogations from surface movement radar. ON The transponder will respond to all interrogations, but altitude reporting is suppressed. ALT The transponder will respond to all interrogations. When airborne, the transponder should always be set to ALT unless otherwise directed by Air Traffic Control. When you are taxiing on the ground, the transponder should be set to GND unless your installation includes a gear squat switch. Aircraft installations that include a gear squat switch will automatically select GND on landing. Push Buttons IDENT Press the IDENT button when ATC instructs you to “Ident” or “Squawk Ident”. This activates the SPI pulse in the transponder replies for 18 seconds. IDENT will appear in the display. FUNC Pressing the FUNC button provides access to the flight timer, stopwatch and altitude monitor function. VFR Pressing the VFR button sets the transponder to the pre- programmed conspicuity code. Pressing the button again restores the previous squawk code. FLT/SQ Pressing FLT/SQ alternates the primary display between squawk code and Flight ID. ENT The ENT button enters a digit in the code selector. BACK The BACK button goes back to the previous digit in the code selector. Code Selector Knob The right hand knob is used to set squawk codes and the Flight ID. The FLT/SQ button selects which will be updated. Turning the knob will highlight the first digit on the display, and the digit can be changed as required. Press the ENT button to advance to the next digit. When ENT is pressed on the last digit, the new squawk code or Flight ID will replace the previous value. If the code entry is not completed within 7 seconds, the changes are ignored and the previous code restored. 1200 VFR code in the USA 7000 VFR code commonly used in Europe. 7500 Hijack code 7600 Loss of communications 7700 Emergency code The Flight ID should correspond to the aircraft call sign entered on your flight plan. If no flight plan is active, the aircraft registration should be used as your Flight ID. Use only letters and digits. If the Flight ID is less than 8 characters long, entering a blank character will end it. Flight Timer The Flight Timer records the time for which the transponder has been powered on and operating in flight mode – either ON or ALT. Press the FUNC button to display the Flight Timer. Stopwatch The stopwatch can be used as a convenient timer. Press the FUNC button to display the stopwatch. Pressing ENT will reset and start the timer. Pressing ENT again will stop the timer. Altitude Monitor The Altitude Monitor activates an audio annunciator or annunciator light (depending on installation) when the aircraft pressure altitude differs from the selected altitude by more than 200 feet. Press the FUNC button to display the altitude monitor enable screen. Pressing ENT toggles the altitude monitor at the current altitude. When altitude monitoring is in use, a small deviation pointer appears adjacent to the altitude display on the transponder. Fault Annunciation If the transponder detects an internal failure, the screen will indicate FAULT and a brief statement of the problem. No replies will be made to interrogations when a fault is detected. Configuration Mode The system is configured when it is first installed by your avionics supplier. Configuration items include the Mode S aircraft address, the aircraft category, and the pre-programmed values for VFR squawk code. To view or change these settings you must use Configuration Mode. Do not use Configuration Mode in flight. Check with your avionics installer before changing the configuration. To enter configuration mode, hold down the FUNC button whilst switching on the transponder. Configuration items can be changed using the Code Knob and the ENT and BACK buttons. Pressing FUNC advances to the next configuration item. When configuration is complete, switch the transponder off. When it is switched back on the transponder will use the new configuration. Low Temperature Operation The TT31 is certified to operate correctly down to -20C, but at low temperatures the display may be impaired. On a cold day you may need to wait for the cockpit to warm up to ensure normal operation.

Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, block diagram, parts list, and Schematics, which are segregated, from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) under FCC ID No: VZI00220 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 This material includes a detailed theory of operation, circuit diagrams, and schematic. As such, this material is treated as highly confidential business information. 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of Trig Avionics Limited’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to Trig Avionics Limited 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by Trig Avionics Limited and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. This equipment is designed for commercial, industrial, and governmental applications. As such, unlike most consumer equipment, this equipment could be used for more than a decade in some cases. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers

The receiver is a completely "no-tune" design - there are no adjustment points. For the transmitter there are no tuning procedures after manufacturing. The transmitter is tuned for spectrum and power by a combination of component location select-on-test and track/pad adjustments in the factory - actual adjustments vary by component batch and individual unit. There are no "tuning components" as such – and all tuning is completed at the factory during production. Units meeting the criteria continue through production and others are returned for diagnostics.
