It appears that a lot of pilots are violating airspace even with GPS on
board.

I would like to hear some feedback as to how pilots are violating airspace
with GPS. I address this in my online book, www.cockpitgps.com. I have
my
hypothesis, but I would like to hear your experience or scenarios that you
have heard involving this issue.

Also of interest is how you might be using GPS to successfully avoid
airspace violations.

Other hypothesis are also welcome.

Thanks,

I've had a couple of *near misses* with airspace. The first time, my GPS
database was outdated, and I realized fairly late that the paper map didn't
show the same thing the GPS map showed. The controlled airspace had
expanded from a 5(?) radius around Montgomery, Ala to 10 (?) miles, and my
GPS had the old data. I looked and looked at the map thinking "that's a
bigger circle than what shows on the magic box"... Then I put a scale on the
map and realized that my eyeball was correct. I was close enough that
evasive action was necessary.

Another time, I was climbing around a series of clouds in a scattered/broken
layer, reached "on-top" and realized that I was surprisingly near Atlanta's
Class "C". Again, I had to make a course correction to avoid the airspace.
Obviously, I focused too hard to pick the best route around the clouds, and
didn't focus enough on my actual position relative to the airspace...
