The following possible hypotheses were listed in the attempt to explain this fact: · Intentional switch-off of the Transponder by the crew; · Transponder failure (continuous or intermittent) · Inadvertent switch-off, through the handling of the Laptop; · Inadvertent switch-off, through the use of the footrest; and · Inadvertent switch-off, during familiarization/operation of the RMU. Intentional switch-off of the Transponder by the crew Discarded: The CVR did not show any indication that the N600XL crew had that intention. In the interviews, both pilots were definite regarding this aspect. Besides, the N600XL crew would not benefit from setting the transponder to STANDBY, as, for example, to fly at different RVSM flight levels, without clearance for that.
