What ED2 message appears when one flap motor fails and the other runs at half speed?

Explanation:
The statement tests how ED2 communicates flap-drive health. Flaps are driven by two motors for redundancy, so if one motor fails while the other continues but at reduced speed, the crew needs to know the system isn’t at full capability. The ED2 message that matches this degraded condition is FLAPS HALF SPEED, signaling that flaps are still moving but not at normal speed because only one motor is driving them, and that motor is operating at half speed. The other messages wouldn’t fit this situation: full speed would require both motors functioning normally; a flap drive failure suggests a more complete fault with the drive system; and a speed warning relates to the aircraft’s speed relative to flap extension, not to a motor fault.
