OK, looks like you'll need a Garmin Flight Stream 110 or 210. What's the difference in the units, other than $550??
on edit: I found a chart:

There will be some RA/TSRA late Thursday, early Friday. If one of you early arrivals could update runway conditions on this thread Friday AM, that would be great!
Darn, I'm only there on 10-9. I'd just like to shake your hand and tell you thanks for so generously sharing your knowledge with us, and helping keep so many pilots in the air.
Automatic, I'd say 60 seconds or less to build the composite. A whole volume scan depends on the "Volume Coverage Pattern" the radar is operating in. Usually, if there's precip around, it's 5-7 minutes. Can be shorter during severe weather operations.
The product is a composite of the single-site Nexrad "composite reflectivity" product. That takes a whole volume scan to render, then national product is generated and transmitted.
Oh, they have, those were the original KC-135 A model. The tanker full of fuel had to heft A LOT more weight than a typical 707. For a lot of take-offs, the KC-135 As would have a very low initial level off, just to build to the book climb speed.
