ATC data isn't critical in a long-term sense, but it's time
critical. By the time someone loads the back-up data, the
whole real-time picture has changed and we'll be having close
encounters of the aluminum kind.

Nobody has to load anything. A few times a year the commercial power
hiccups. When that happens you hear those ugly powering down sounds.
Then the backup power comes online, then everything resets and you are
back to where you were. Whole deal might last 10-15 seconds but it
seems like forever if you have a lot of traffic. No data is lost in
this process.

Damn, we run our 24/7 order entry system from conditioned power/battery
packs which means if the power burps, or even goes down for several minutes,
no one in the computer room would even know. I'd say ordering products is
less critical than ATC's services.
