The new battery I ordered arrived this week.

I was in Wichita all week, doing some Global Express flight testing.  It was strange to be in a land without snow.

The weather this weekend was fairly cold, so I didn't go out to the hangar to install the new battery.  I've got two electric radiant heaters that do a pretty good job of keeping me warm while I work, as long as I stand right in front of them.  But, they wouldn't be much use if I was kneeled over in the rear baggage bay, replacing the battery. 

Hopefully next weekend will be warmer.  If not, I'll cobble together some sort of extended air duct off the big electric heater I use to preheat the engine.  Perhaps that could get enough warm air in the baggage area to keep it habitable.
