12 Days in and still no commitment from any Transport Authority, Airline or Aircraft producer that Transponders be permanently locked in some way???
Will we learn nothing from this and 9/11 ???
OK here we go again on this issue. A transponder is an electronic component that as such can short out, cause phantom 76 (emergency) codes or in my case a phantom echo 100 feet above me. Without an off switch I would have had to land or vacate the control zone. Any electronic component needs a CB and/or off switch.
