Outside here. We use the same Cat 2 procedure at Xjet and have been for years. It's really not hard. Me and my sim partner did one during CTP, I was in the left seat, sim partner with no jet experience was in the right. We saw the runway and landed. It's really not a hard procedure at all. Relax.
We have an entire briefing and systems check that's performed before the approach, along with modified checklists and callouts. We also do the approach flaps 22 to facilitate an easier go around from 100 feet.
We're also supposed to use this procedure any time the RVR is less than 4000 or 3/4 mile.
