I had a flight right before I got my CFI that thought me a lot about actual flying with regards to weather, flight planning, fuel conservation, ect. I had about 350 hours when it happened and thank God I wasn't alone to deal with it. From that point on I made a point of it to teach every student how to handle these things. Sure it ate up a few more hours but in the end not one of them complained. CFI's should be teaching this stuff to private pilots, Instrument guys, and commercial students should be able to do it on their own without help before ever getting to take that ride.
ATP should be required to do this job given the current set up of training here in the US. The commercial ride is based too much on maneuvers and less on decision making. I could care less that my pilot can do an effective lazy 8 if he can't get around a a build-up without having a meltdown. Real world rides would be great, but that takes time.
