Hello guys, i was look at this picture today

Notice something is open to the left of the engine, on the fuselage. Is it in any danger? Did somebody forget to close something??

That is the cabin pressurization outflow valve and, on the ground (or very near to it) it SHOULD be open.

It's the pressurisation Outflow Valve. It closes when the #2 Eng Throttle is advanced for TO.

It is for cabin air pressurization.

The people inside would be very unhappy if it weren't open.
PIA777, it is venting the excess cabin pressure, If it were closed the passengers would be subject to a pressure about the same as in 40 feet of water. A very annoying feeling to most of us.

This is another one of those topics that comes along every week or so. The funny thing is that the topic is always headed "Is this DC10 in danger?"

You are right MD11LuxuryLinr. I wonder why it's always a DC-10? Perhaps because the outflow valves on the -10 are so obvious?

Chris,
Because it uses the curvature of the earth to take off... it can just fly straight and level with it´s 5 APU´s and does it while the ground drops away from it...
