USA FAA Mandated Security Screen Doors

[MEL_Traveller]

I wonder if there may also be a mandate in the future to have 2 people in coughpits at all time coming. In which case the FA up front would enter the coughpit while the pilot is relieving themselves thus a barrier adds extra layer with people shuffling about and such.

As for 2 people in the coughpit at all times, I'm surprised this isn't a mandate these days still given the various incidents we've had over the years with a pilot going rogue.

Many airlines did, after Germanwings. I read the FAA still mandates it in the US, and some other countries do to.

Other countries and airlines have not mandated it.

Would it prevent a committed pilot attempting to crash the plane? Dunno.
