Default RE: 150 meter rule.

Hi,
Just a cautionary note;
G-Earth views can be quite oblique depending on patch location relative to the pass over track.

Brian,

You can see the obliqueness from some of the photos themselves, but I would add that the distance shown on the FARM photo agrees precisely with the 150M pole they have, and even a 5% error which to me seems improbable is only 7M. Certainly I wouldn't go setting any Pattern poles based on these pictures, but simply to say the tree line is roughly 150 and the field beyond is 250, for that I think we are well with in the tolerances of an oblique view. Not that I don't fully agree with being cautious

Planning my first trip to the practice field today to get a better understanding of what I'm talking about and to see just how much of a difference it makes for my style of flying.
