Talking about electrical power surges being bad. So, we started using CPDLC to talk to enroute ATC and get clearances. I'm sure you've heard of it. Some glitch in the system caused some bad clearances to be followed from a previous flight. How to fix that? Making sure the ATC log is erased wasn't good enough. After each flight our shutdown checklist has us kill power to the entire airplane for 10 seconds to make sure everything is erased from the memory. I've never seen so many status message pop up once the power comes back on. Big relays going click and clunk. Just can't be good for the airplane...
