MST 67A Pilot’s Guide Introduction INTRODUCTION Your Honeywell transponder is a radio transmitter and receiver which operates on radar frequencies. It receives interrogations from ground radar, airborne radar or TCAS, then returns a coded response of pulses to the interrogating system. The reply can be any one of 4,096 codes, which differ in the position and number of pulses transmitted.
Controls and Displays SECTION I: CONTROLS AND DISPLAYS SECTION I DESCRIBES CONTROLS AND DISPLAYS OF THE MST 67A. Note: If power is removed from the MST 67A, it will reset in the last used condition.

Controls and Displays ACT 12 R The Display Window displays the 4096 ATC code selection and whether transponder No. 1 or No. 2 is active. The letter R blinks on the CTA 81B when indicating the interrogation reply of ATCRBS transponder only. 1 ATC 1-2 selects the active transponder. The other unit is placed in standby. ATC 2 NO ALT OFF ALT ON/OFF turns altitude source ON or OFF. Concentric knobs select the 4096 ATC code in the display window.
MST 67A Pilot’s Guide Controls and Displays FUNCTION SELECTOR CTA 81A/C/D CONTROL UNIT ONLY (SELECTS OPERATING MODE) ALT OFF ALT ON TA STBY TA/RA TEST Moving the spring loaded knob to TEST position for one second initiates a comprehensive self test lasting approximately eight seconds. Refer to the Test section in the Appendix for a detailed description of test functions. STBY places Mode S transponder and TCAS system in standby. Use this position during ground operations.
Controls and Displays FUNCTION SELECTOR CTA 81 B CONTROL UNIT ONLY (SELECTS OPERATING MODE) TA TA/RA ATC 1 ON ON ATC 2 STBY STBY TEST TEST The left ATC 1 TEST position (CCW) tests the Mode S Transponder. The right ATC 2 TEST position (CW) tests the ATCRBS transponder only. Moving the spring loaded knob to either TEST position initiates a self test in the respective unit. Refer to the Test section in the Appendix for a detailed description of test function.

Controls and Displays KFS 578A FUNCTION SELECTOR & ATC CODE SELECT R ALT VFR ON PUSH SBY FL TST The outer concentric knob on the right selects the transponder mode of operation. Rotating the function knob (CCW) to the TST position initiates a comprehensive self test lasting approximately eight seconds. All segments of the display are illuminated for 2 seconds, then the code window will display the encoded altitude for four seconds, then the control unit will return to the previously selected mode.
MST 67A Pilot’s Guide Controls and Displays PS 578A TRANSPONDER CONTROL UNIT PS 578A Single or Dual Mode S Control Unit (Dual Unit shown). PS 578A CONTROLS AND DISPLAYS The PS 578A Control Unit is the master control for the transponder. The PS 578A will also display the selected 4096 ATC code and current mode of operation in the display window. Versions are available to control one or two transponder. A “Fail” annunciation indicates failure of the selected transponder, antenna or control data.
Controls and Displays FID allows entry of an alphanumeric flight identification. Selecting the right inner pushbutton will cycle through the eight characters to be changed. Rotating the right (Pushbutton) inner knob will change the contents of the selected (flashing) character. The inner concentric knob on the left includes an on/off switch. Note: All knobs are continuous rotary and do not roll over or stop.
MST 67A Pilot’s Guide Controls and Displays The VFR code can be programmed to be any code by the following technique: a. Place the function selector to VFR. b. Select the VFR code as required. c. Push the Ident (IDT) button, or wait 3 seconds, or rotate the Function switch to the desired mode.
Controls and Displays The Display Window displays the ATC code selection, whether transponder #1 or #2 is active, transponder mode, transponder ident and own aircraft flight level (in TEST) 1 IDT All display annunciations are seen during the control unit self-test. The "R" annunciation is only seen during self-test. "FL" on the control unit is only displayed during self-test and indicates the transponder's encoded altitude. Continuous FL mode is selected by activating Ext.
MST 67A Pilot’s Guide Controls and Displays SBY places the Mode S Transponder in standby. SBY is annunciated in the display window. Use standby during ground operations. ON activates the selected transponder without altitude reporting. ON is annunciated in the display window. ALT Activates Mode S transponder with altitude reporting. VFR Selecting VFR for more than 3 seconds changes the ATC code to the pre-programmed VFR code (typically 1200).
Controls and Displays PS 550 TRANSPONDER CONTROL UNIT PS 550 Single or Dual Mode S Control Unit (Dual Unit shown). PS 550 CONTROLS AND DISPLAYS The PS 550 Control Unit is the master control for the transponder. The PS 550 will also display the selected 4096 ATC code and current mode of operation in the display window. Versions are available to control one or two transponder. A “Fail” annunciation indicates failure of the selected transponder, antenna or control data.
MST 67A Pilot’s Guide Controls and Displays The TST push button initiates a comprehensive self-test lasting approximately eight seconds. All segments of the display are illuminated for 2 seconds, then the code window will display the encoded altitude for four seconds. The MODE push button sequentially selects the ATC, FL mode, FID and ADC. ATC Mode - Allows entry of the four digit ATC code.
Controls and Displays ALT OFF activates the selected transponder without altitude reporting. ON is annunciated in the display window. XPDR Activates Mode S transponder with altitude reporting.
MST 67A Pilot’s Guide System Considerations SECTION II: SYSTEM CONSIDERATIONS SECTION II EXPLAINS CONSIDERATIONS OF THE SYSTEM; WARNINGS AND LIMITATION, CAUTIONS AND NOTES. WARNINGS AND LIMITATIONS Refer to the Aircraft Flight Manual for the specific operational features of the transponder installation. CAUTIONS None NOTES The MST 67A requires the availability of a suitable encoding altimeter providing altitude input in order to report altitude.
Appendix SECTION III: APPENDIX THE APPENDIX INCLUDES THE TEST FUNCTION, A GLOSSARY OF TERMS AND RECOMMENDATIONS FOR POST FLIGHT REPORTS. FUNCTIONAL AND AUTOMATIC SELF TEST The Mode S transponder Functional Test determines the operational status of the entire system. The test is initiated by rotating the function selector knob on the Transponder Control Panel to the TEST position. Thereafter, the test continues automatically for a period of approximately eight seconds.
