I've been watching 1090ES traffic on a FlightAware (Piaware) receiver
for several years. 60 Miles N of Denver International, so see lots of
jets headed up to Seattle area. I don't ever remember seeing a jet
misidentify as a piston plane on my system.

There used to be some occasional errors, like a heading always showing N
regardless of actual track over the ground, and position reports wildly
bouncing all over the place, but those seem to be cleaned up now.
