The GCS is only a basic feature of the processor, basically differentiates between the "type" of echo that solid objects reflect from those that water do. I use the GCS a lot. I use it in my first few scans while I figure out the tilt, and while on the ground when taking off with cells around the airport. Also, about the tilt, auto-tilt sucks and about the manual tilt angle varying from aircraft to aircraft is just installation error. When the radar is inspected, manitenance usually checks the mounting of the antenna. It could "de-adjust" with a few hundred hours flying in turbulance. Also, some antennas are leaning to one side, that's the reason you get more ground return from one side. I think it's a pretty good radar, I used to fly lights with the old Bendix R160 black and white, and the radar in the CRJ is awesome compared to that. Also, I wish we had stormscope combined with radar, it's more useful than most people think.

Also, rembember, interview question:

Q-What's the best weather avoidance device on any airplane?

A- TCAS !!!
