Changing squawk on transponder...
I've got two questions:
1. Do you switch the transponder mode to SBY, when changing the squawk? Some say you should, some say it does not matter (as for me, I usually do not bother). So should we, or not?
2. One of the arguments for switching to SBY is that when you set 77XX (where XX may be whatever you want), you set off an alarm. Is that true, or only 7700 does make the radar screen red?
