There are many aspects to the operation and design of airplanes that are
"traditional" simply because the results of something going wrong is so much
more
severe. If your car's engine quits you coast over to the side of the road and
call a towtruck. It the engine in your plane quits you might be able to
dictate a brief will to your lawyer over the cell phone but that's about it.
And
the FAA has no sense of humor.
When I was in college I remember being told that when starting a plane in
cold weather it is required to pull the plane in the hanger and warm up the oil
since they use single grade oils. I suspected that this was still the case.
