I've jumpseated on plenty of mainline aircraft (particularly the -88) there the pilots have done the same thing. I kept my laughter to myself.
Were the -88s you mention Delta ? If so, I'm a bit surprised you saw people who didn't know how to operate radar (if that's what you meant). They aren't exactly inexperienced people and the DL POM has a pretty good radar section with adequate theory.
But, Dumb Pilot is correct in that little time is spent "teaching" people how to operate wx radar these days. Many years ago,
as an example, UAL had a dedicated radar course complete with their own manual and sufficient time addressing the subject in class as best they could. However, that's history.
Like FMS, learning how to operate radar is very much hands-on and experience based. However, there is now ample material available for people to bolster their knowledge base: books and some pretty good articles, much available online. I think I remember Robert Sumwalt wrote a series of good radar articles.
I can recommend a good text written by a DL guy:
http://www.amazon.com/Airborne-Weather-Radar-Users-Guide/dp/0813813638
I don't know where Amazon comes up with those prices but it's a very good radar textbook. (I have no financial interest in this book)
I suppose the first step in correcting a lack of knowledge would be recognizing that lack. For new people, recognizing their employer's CBT didn't amount to much would be a hint. The less experience that new person has, the more obvious that training deficit should be. Asking questions of the captains they fly with would be a good start; most captains will have a good knowledge/experience base.
I had the privilege of flying with some old captains whose experience involved flying before airborne wx radar. The stories would make the hair stand up on the back of your neck.
Flying today with an inadequate knowledge of radar use/operation would be better than having no radar but it's pretty easy to get educated on proper operation. It just requires recognizing the need and having to motivation to fix that.
Ya'll be careful out there.
