Bahadir, All that is required by the proposed change is a one-button selection of an emergency transponder code, and that once activated, it cannot be switched off while airborne. It makes it more likely that 7500 can be activated when necessary so that ATC is alerted earlier than otherwise might be the case. I think this makes great sense. It is fairly cheap and only adds to the convenience for the crew. So why not? In fact, modern all-push-button transponders should have dedicated buttons for all special codes (1200, 7500, 7600, 7700 etc) anyway. Makes life much easier.
