The PC-12 is supposed to be a very good plane.  He was probably just
being friendly, and decided that it wouldn't hurt to get a
cross-check.  I think that the first officer was the pilot flying; I
should have just handed the GPS to the captain and let him play around
with it for a while.

Even if his GPS wasn't giving him groundspeed information (and I have
no reason to believe that's the case), he could easily get it with his
wristwatch by timing a leg between two waypoints; time, speed and
distance problems are not rocket science (right, Jon?).


All the best,


David
