Becker 4404-1 Transponder Behaviour
Hi
A question for those who fly with Becker 4401-1 transponders. Normally the "Reply Indicator" triangle on the display of our transponder flashes briefly when the unit is interrogated, but otherwise it remains off. Today I noticed today that it was displayed continuously. This was when I was at low altitude and the transponder was shielded from ATC radar by a mountain. When I climbed higher it seemed to behave more normally, but still displayed for several seconds on some occasions. Is this normal behavior for this unit that I have just not noticed before, or has ours developed some kind of fault? I can't help thinking that a continuously "Reply Indicator" implies continues transmission, which can't be healthy. Thanks Ian |
