I've always disagreed with the concept of banning visual circling approaches in the sim. Yeah, they're really hard work coz there is so much happening with config and allowing for wind etc. There in lies the value in the sim - you have to work at it. It improves your management, situational awareness and basic flying skills. Probably a good idea not to plan on doing one unless you're backed into a corner but then you will really need to know how to do it right.
What if one day that's all you've got - think twin ETOPS diversion ports?
