Modern airborne radar is better than the "crap" we had 30 years ago? Surely you jest.
I could see the control tower on an airport from 5 miles out with the old radars, I could see individual airplanes parked on the ramp. I could see the weather clearly and make my own decisions as to the amount of water carried by parts of the cloud and thus make my own decision as to the parts to avoid. I flew years and years in the tropics and experienced hundreds of severe encounters at some of the worst levels (around 13,000 to 15,000 feet).
I give you the new radars are easy to use and they do the deciphering for you, but often they are wrong and always exaggerate. They are useless for fine work, cannot do even a small part of what was done by the older radars. They are cheaper to buy and to maintain, and are much lighter, so I see the reason for them, but don't kid yourself that they are better for the purpose they were built.
No Boofhead, I do not jest. They were crap.
I cut my ITCZ teeth on B732's in West Africa in the early 80's. My prevailing memory of those old radars was dodgy unreliable displays, lots of twiddly knobs to play with, and the definite impressioin that half the time they were serving you BS. Maybe because my crusty old Captains weren't 'adept' enough at twiddling the knobs. Or maybe because it was a black art that required a lot of concentration to work right - the kind of time you don't always have when racing around at 500mph in a storm filled sky.
Indeed a pair of my colleagues were almost killed by one of those cranky boxes. They made the mistake of interpreting a gap in the display as a hole. It was in fact a 'Super Cell', blanked out by radar attenuation. The aircraft was almost a write-off. The damage was impressive.
C Band Radar requires larger antennae, and other heavier equipment (so I'm told) so other solutions would be developed by necessity. The new radars do not require anything like the artistry of the old systems to give you useful info. When you say 'pilots don't know how to read/operate their radar' and instead recommend a return to those prehistoric glow tubes of old - you are being a bit of a luddite, nothing more. There is every likelihood such a system would create more problems than solutions. So I'll keep my modern, stabilised, bright, colour contoured, computer enhanced, map overlaid MODERN Wx radar thanks. If you want you can always switch off the automatics and play away to your hearts content with the raw data, ground clutter, noise, and all the other rubbish.
The bottom line is - the new stuff shows the weather very well in my experience. You use it to avoid - not penetrate CB's. Doing otherwise is the only possible explanation I can come up with for your love of those old boxes.
Good luck.
