Transponder on A320
Just a quick question
In flight if I should change the squawk code on the transponder, do I need to put it to STBY or not.
I know in the old cessna's I used to fly we had to do this, but I have been told 2 different things by 2 different captains.
1 said "YES" always, another said "No need"
Thanks a lot, for any ideas
