Ozjet plane forced to land after wing failure
Airscrew
The leading-edge devices (flaps and slats) move automatically as certain trailing-edge flap positions are reached. There is normally no facility for moving them independently. However, it is possible to move them out (only) all together using an emergency system if the flaps do not deploy, and in doing this, because of the smaller hydraulic pump involved, the devices may deploy unevenly at first causing a slight lateral instability, easily dealt with.
Handling the aircraft with assymetric l/e devices isn't much of a problem.
