Can someone from European/UK ATC advise us whether or not you want an aircraft in a rapid [unplanned] descent to squawk 7700?
Our training department is saying in Europe, ATC don't want us to change the assigned code in an emergency descent, it would "cause more problems" and you "can see we are in descent"
Thanks
As Arkady has alluded to, by squawking 7700 it tells us that you have a problem. That, coupled with us seeing you in a rapid descent, enables us to get other a/c out of your way PDQ
