re from captain87
If the RAT stalls or if aircraft is on the ground with speed below 100 Kts, the emergency generator has nothing to drive it.
The RAT stalling speeds for the different types are:
A319: less than 125 kts
A320: less than 140 kts / less than 125 for modified A320
A321: less than 125 kts
Note: This speed limit is for electrical power and the RAT will continue to supply hydraulic power to much slower speeds.
Regards
