If all the passengers ran to the back of a 'plane...

What would happen?
Nothing?
Bad things?
Sake of argument an a320 type.
200 people?
Well IIRC an A320 weighs in at 50 tons - and if that many pax did rush to the back it would mean a shift of about 15 tons to the rear which is a big shift of total weight to say the least. Im going with b) bad things.....Nothing?

That would be bad for two reasons. Not only would putting the centre of gravity outside limits could possibly cause a loss of control or at best limit the pilot's options. But putting the c of g so far back would reduce the leverage of the tail, making control even harder. So at best safety margins would be reduced.

Would the resultant shift in weight be beyond what the plane could cope with, or would it just be a case of re-trimming?
Also, if it happened on the ground, could the passengers tail-tip the plane?
That's what I was meaning, along with would auto pilot be able to cope?Also, if it happened on the ground, could the passengers tail-tip the plane?

Okie doke, thanks.Thanks for the notice about the 747 accident video r8steve. Like you, if it's got fatalities then I'll skip it.

There's a video on youtube of cargo shifting to the back of a cargo plane when it is taking off.
It doesn't end well. I would search for it and post it but as it involves people dying i'd rather not.
The 747 at Bagram? Horrific.It doesn't end well. I would search for it and post it but as it involves people dying i'd rather not.
Depends on the size of the plane. A large passenger aircraft, 747, A380 etc. All the passenger running towards the back will affect trim etc. but not control threatening. A small aircraft will probably result in loss of control.
In this case they all ran to the front, and it ended badly.

Therefore, not only was the aircaft balance aft biased, but the elevators were jammed at the point of rotation. There was nothing the crew could do from that point on.
