After spending the last hour and a half shoveling heavy packed snow and ice that the snowplow driver dumped all over my sidewalk and driveway (which I had already cleared the last time it snowed a few days ago), I am tempted to go on a rant and vent about how I think winter in Wisconsin sucks and share my theory that snowplow drivers are evil, sadistic people who relish making winters even more miserable for everybody.

The normal engine startup sequence for Citation 560XL aircraft removes power from the avionics system, causing it to drop offline. The reason for this is the avionics are isolated from the start system. SB560XL-24-14R2 allows the avionics to stay online by using the APU generator during engine start.
