What would happen to a passenger plane if one elevator is lifted up and one elevator lifted down?

Do the two actions cancel each other out? Or would the plane go into some undesirable position?





Also, there are two controls in the cockpit, one for each elevator right? Why not just one control for both?|||This cannot happen. If it did, you would probably have something like porpoising or dutch roll happen.



The elevators, like the ailerons, are controlled via the control column or control stick. Pulling the column back raises the elevators and raises the nose of the aircraft. Pushing it forward causes the opposite effect. The elevators are not controlled independently, they are linked together.



In cockpits with two sets of controls, the controls are linked mechanically. You cannot pull back on one control and push forward on the other.



As an afterthought, you really should change your screen name. Yours are just stupid as hell.|||This can happen in the ATR (apparently military pilots aren't gods that know everything).


Yes, there are two control columns that connect to each other under the floor of the pilots. In the case of the ATR there is a mechanism that allows for the two columns to "slip" out of sync if you apply enough pressure (not going to happen unless you force it to happen).


The aircraft is still able to fly, but it is an emergency situation and there is a checklist


Bank is limited to 30 degrees. Max speed is 180 kts. Angles steeper than 4.5 degrees is prohibited. Load is limited to 2 g's. Landing speed is increased 10 kts. and landing distance is increases 1.13.|||It would create an awkward rolling movement. Similar to ailerons.



In most airplanes the elevators are linked, and it would be impossible. In some fly-by-wire aircraft it is possible. In the F-18 for example, the elevators assist in rolling the aircraft.



Also some aircraft have the two elevators linked, but can be disconnected in an emergency, if one becomes jammed for example. An example of this would be the Dash 7 or Dash 8 aircraft.|||No, the two controls in the cockpit are for two pilots, but they're linked together to both elevators. Except in some modern fly by wire fighter aircraft, they can't move separately.





If they could, however, it would cause the airplane to roll just like using the ailerons, but much more slowly because they're smaller and so close together.|||Honestly, I don't know what would happen but I wanted to respond to some of the incorrect answers. While the elevators are linked, so that each yoke moves the entire elevator, there are lots of planes that have a disconnect lever. You could pull that and do exactly what the asker is talking about. This type of linkage is there so that the pilots can still control the plane if the elevator gets jammed.|||Nothing happens if the elevators move in opposite directions.





There's one control for the elevators, namely, the yoke. There are two yokes in many airplanes, but they are connected together and move as one, except for certain very exceptional circumstances on certain airplanes (in emergencies).|||IF , I said "IF" it could....





Ever seen what Fletching on an arrow does to the arrow ?





Anywho... The only plane your gonna see any kind of that action





would be "Fly by Wire"....





I could see it using that sometimes...
