In response to post #2 above. Just some more thoughts


Actually FH, if you go to the AMA Competition directory and do the math then the numbers are surprising. (Yes I do fly pattern, and yes I have been a Pattern contest judge.

The book says that max altitude from the pilot's point of view is 60 degrees up. The max depth of the box is 175 METERS from the JUDGES who are 10 Meters behind the pilot then the trig works out that the theoretical top of the aero box is 937 FEET above the pilot's eyeballs, or 942 feet above ground!

And since the trend in pattern flying has been toward the BIG slow flight patterns I'll bet we're definitely exceeding 800 feet AGL at most pattern meets.
