Excellent, George. I make no apologies about the one example not working. It was meant in the spirit of degraded accuracy vs stated criteria. In the sense of fairness, George, would you mind posting the spreadsheet? It shouldn't contain the final set of values that will be applied to the challenge set, but it will permit others to review the calculation. I believe at this point that we just need Frank's buy-in. Mr. Reed? Jim - do you accept the conditions that are posted by George. They are 1) 10% (1 knot in 10) velocity scatter 2) 1 arc minute in true altitude scatter 3) Centered around Noon (but not precisely so. We don't want the apex of the parabola to contain an altitude) 4) 13 values scattered in time. About 1/2 before and about 1/2 after LAN, with no periodicity (not every 5 minutes, some variation can be expected. In review of other posts by Henry and Geoffrey, it seems that there are published sets of limitations. Would one of you gentlemen post either the reference or scan in the appropriate section, since it seems to be at your fingertips? Thanks!
