Yes...
Yes, the old RAT needs at least 140 KIAS AND gear up to work. There is electrical logic with the LGCIU 1 also...but not to confuse the topic. (I have to look it up, to be honest.)
But, say you are on ELEC EMER CONFIG (on the RAT) AND you've also lost Green System (for whatever unrelated reason)....so, you have to crank the gear down. No problem, except in the event of a go-around....that's when you have a problem.
That's why you, in this double-failure-unrelated-event, you have to get some speed (at least 180 KIAS) AND undo the logic by pulling the LCGIU circuit breaker. By doing these two things, you'll be able to re-gain the RAT function. (Also, you'll have to reset the RAT button, as well.) But, you can actually have the RAT work with the gear down.
Again, this applies to the old, smaller-design RAT. The new, big RATs will work down to 125 KIAS and will work with the gear down, as well. Thus, the only restriction of the new RAT is to maintain at least 125 KIAS.
