Don't the pilots have the master switch to locking the doors in the cockpit on the plane before takeoff and unlocking them before landing so doors can be opened?

 

If so why haven't I noticed them before?

 

I would imagine for security reasons they wont model any security features. It would be a no no.

A switch like that would cause problems during a possible evacuation. 
I don't know any plane where you can find one.
Additionally: Why would the cabin announcements "all doors in park" and "all doors in flight" still be necessary then?

Locking doors on a modern tubeliner? There are only two kinds of doors with locks in the entire airplane: the cockpit door and the lav/crew rest doors. That's it.

That's why I said security reasons. I didn't understand he meant all doors.

Don't worry Richie, I was responding to the OP, not to you :wink:

Of course, the switch to unlock the cockpit door is located inside the cockpit.

Oh, just to make sure. Was the question about the cockpit door or the passenger doors?

I was agreeing with you.

If we are talking about the passenger doors inflight then there is no need to have a lock on them because the pressure inside the plane will hold them shut. They are designed that way for safety. The door is basically a plug in a hole in the fuselage. As the pressure is increased inside the plane the door is effectively closed tighter and tighter. To open the door inflight you would have to have super human strength. Unless the aircraft depressurised that is.

The only door the pilots have a switch to lock is the cockpit door.

Kind of makes you miss the 727/DC9 days, when rear doors were common, i.e. DB Cooper

I love the 727 and the DC-9. I flew a DC-9 Simulator once (Birthday treat). Was a dream to handle, second time round I greased the landing so well that I hadn't realized we were down (thought we were floating on ground effect or had over flared). Nothing like I expected. I just wish i was old enough to have flown on real ones.
