Per,
I've let a handheld unit aquire in a plane and measured speed in MPH and
Knots. We were cruising about 458 mph! (Boeing 737 I think) From what I
understand as long as satellite aquisition isn't a problem they are accurate
up to the limit. Which, on the Magellan 315 is 1,240 mph (not that I ever go
Mach 1.65 or so! I try to keep Vinnie below the speed of sound)
Maybe they had power problems or line of sight problems with the satellites?
