Wx Radar Factor
Thanks for all the good comments.
It is not my opinion that the last generation of radars are unsafe, rather that the airlines give only lip service to radar training. UAL used to have an excellent radar training program in Denver, but it is long gone. I have heard of no other airline that does an adequate job. That's the main basis for my believing the new multi-scan radar provides a better margin of safety.
At this point, is it more economical to upgrade the radar and provide a basic understanding of it, or to provide extensive training to all pilots in optimum use of the old prior generation radar?
