What will happen if one of the two motors that drives the flap panel fails?

Explanation:
Two motors provide redundancy for the flap drive, so if one fails the system can still move the flaps using the remaining motor. Because only one motor is now doing the work, the flap movement is slower—about half the normal speed. The ED2 display communicates this degraded condition to the crew by showing FLAPS HALF SPEED, so pilots know the flap rate is reduced and plan accordingly. This preserves control and requires no automatic retraction or complete stoppage, which is why the other scenarios—full failure, automatic safe-position retract, or staying motionless—don’t apply in this situation.
