co Pilots are not able to take control of the aircraft. A solution would be to be able to switch controls form the pilot / co-pilot via action menu. otherwise there is no sense in having a co-pilot.

get into a chopper as pilot and a second guy as copilot try switching controls ..
Your friend dslyecxi even made a mod for Arma 2 solving this.
Switching controls worked for my friends and me so far. The pilot has to unlock the controls, and the copilot has to accept it. Then he gains control over the helicopter. Worked pretty well for me.
