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 knob on the right hand side 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. 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. Aircraft installations that include a gear squat switch or configured with an automatic air/ground system will automatically switch the transponder to Ground Mode on landing or whilst taxiing. GND will be indicated on the display. KT86 DRAFT COPY 3 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. VFR Pressing the VFR button sets the transponder to the pre-programmed conspicuity code. Pressing the button again restores the previous squawk code. Pressing the VFR button whilst in Flight ID edit changes the Flight ID to the pre-programmed ID set up during the configuration of the transponder. FUNC Pressing the FUNC button provides access to the flight timer, stopwatch, Flight ID editing, ADS-B monitor (depending on installation) and altitude monitor function. ENT The ENT button confirms selection or presented options. Squawk code entry Press any of the numeric buttons (0 through 7) to change the squawk code. A new squawk code is set when the fourth digit is entered. If the code entry is not completed within 7 seconds, the changes are ignored and the previous code restored. Some standard squawk codes are listed below 1200 VFR code in the USA 7000 VFR code commonly used in Europe 7500 Hijack code 7600 Loss of communications 7700 Emergency code 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. EN 4 DRAFT COPY Flight ID entry Select the Flight ID screen using the FUNC button and then edit the Flight ID using the numeric buttons. The lower portion of the display shows the alpha numeric characters selectable through multiple presses of the numeric buttons. When the correct character is shown in the flight ID section of the screen, press the ENT button to accept and advance to the next digit. The flight ID is terminated with an “space ” character located on the 7 button. When ENT is pressed on the end space, the new Flight ID will replace the previous value. If a button is not pressed for 30 seconds, the changes are ignored and the previous code restored. 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 the “space” character will end it. 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. ADS-B Monitor The ADS-B Monitor is only available on installations that include an ADS-B position source. The ADS-B Monitor provides a display of the position information that is being transmitted in ADS-B position reports. This can provide confirmation that the correct information is being transmitted, particularly where the GPS source is remote from the transponder. In the event that valid position information is NOT available from the GPS, the latitude and longitude display will be replaced by dashes; if no valid latitude and longitude is shown then ADS-B position information is NOT being transmitted. Loss of ADS-B position information will also result in a WARNING message being displayed. DRAFT COPY 5 Warning Messages If the transponder detects a problem, the screen will indicate WARNING and a brief statement of the problem. Depending on the nature of the problem, your transponder may not be replying to interrogations. Note the message on the screen and pass that information to your avionics maintenance organisation. The WARNING message should clear when the event has cleared. Press ENT to clear the message at any time; if the fault is still present the message may reappear. 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. Some FAULT indications can be recovered by switching the transponder off and back on again, although in all cases a FAULT code implies that there is a fault with the transponder or the inst…

July 30, 2021 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Applicant: Trig Avionics Limited Heriot Watt Research Park Riccarton Currie EH14 4AP United Kingdom Re: Confidentiality for submittal information regarding FCC ID: VZI01905 PRODUCT: Aviation Transponder operated under part 87 Dear Sirs: Trig Avionics Limited requests that the material in the Schematics, Operational Description, block diagram, and parts lists be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459, following grant of the application. In support of this request, Trig Avionics Limited submits the following: CONFIDENTIAL FILES Schematic VZI01905 Conf Schem.pdf Block diagram VZI01905 Conf BlkDia.pdf Operational Description VZI01905 Conf OpDes.pdf Parts Lists VZI01905 Conf PartList.pdf 1. 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: VZI01905 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This material includes a detailed theory of operation, circuit diagrams, and schematic. As such, this material is treated as highly confidential business information. ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 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
