Don't know what commonality there may be between the Legacy and ERJ 135 but this bit from post #63 at
http://www.pprune.org/forums/showthr...=281098&page=4 perhaps raises some interesting questions.
I can remember some small glitches that popped up when the airplane was initially introduced in the U.S. but nothing big....well sort of. I can still remember being cautioned about the problem with the transponder, how if you start to change the code and then don't touch the knob for more than so many seconds the transponder would switch off. That's right, no warning or a default to the last code inputted, it would just switch off. Remember the crash in Brazil of the 737 after colliding with a Legacy?
