My understanding is that it's OK for thrust reversers to be inoperative so long as you know it before landing, but if you've set landing speed and touchdown point based on them working, and they don't, that's a problem (although it should be recoverable), but worst of all, if *one* of them fails (i.e., asymmetric reverse thrust on a 2-engine aircraft) that's a very, very bad problem. -- Michael C.
