Studying the gouge and I feel pretty good for the interview next week. One thing I've been seeing lately is a question about the significance of 500rvr for takeoff and the considerations it should yield.

I'm new to the 121 world, and we hardly ever used RVR in my mil aircraft. Obviously 500 is super poor visibility. Aside from simply needing a takeoff alternate, are there other considerations you account for with that type of vis?

Thanks in advance!
