increases applicability to include GTX 33 and GTX 33D transponders and requires transponders to have software version 3.06 installed (transponders with version 3.03 are not affected). The Amendment resulted from advice to the FAA from Garmin that software versions 3-04 and 3.05 inadvertently removed the correction to not suppress the S1 below the MTL and is issued to prevent interrogating aircraft from possibly receiving inaccurate replies due to suppression from aircraft equipped with the GTX 33/33D330/330D Mode S Transponders when the pulses are below the MTL. The inaccurate replies could result in reduced vertical separation or unsafe TCAS resolution advisories. |\n| --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n|     | The original issue of this Directive became effective on 5 August 2004.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |\n\n![](image.001.png)  \nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n2 March 2005","sortOrder":0},{"sectionNumber":"AD/RAD/81 Amdt 1","sectionType":"part","heading":"AD/RAD/81 Amdt 1","content":"## AD/RAD/81 Amdt 1","sortOrder":1},{"sectionNumber":"Garmin Mode S Transponders","sectionType":"part","heading":"Garmin Mode S Transponders","content":"## Garmin Mode S Transponders","sortOrder":2},{"sectionNumber":"4/2005","sectionType":"part","heading":"4/2005","content":"## 4/2005","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":true,"description":"Yes.
