Narrative:

Just started our descent into ZZZ. Got engine 2 air system fault. Had put the #2 thrust lever to idle; per the ECAM. Ran com. Message persisted so we declared and landed with 2 engine at idle. The engineer that the captain spoke with on the phone after the event; made it sound like we could have used the engine? The operations manual (OM) procedure just sorta left us hanging. Didn't say we could try the engine; use the engine or shut down the engine. Or to land as soon as possible. I think there needs to be another action step maybe? If message persists or not... If the engine was fine; would have been nice to have. They ended up just deferring the issue; but didn't actually do anything physically to the engine to fix. Just a paperwork deferral. So that leads me to believe we just added risk to our approach and landing for no reason? Maybe the OM procedure is fine. But a little more info in the OM; in the moment; would have been helpful to me. Recommend looking at it.
