Zellmld,
I have had a response from someone at Boeing and they do not have an issue with the revised arc height conversion rule and implied that the results will not differ from the adjustments of the past.
I gave this more thought. I still don't have the new spec, but if the only change is the addition of "for all arc heights greater than 0.005", then there isn't much change from the old spec. Magnetic arc heights greater than 0.0050" are treated the same. The oddity the added text creates is values between 0.0050 and 0.0065 resulting in an adjusted value below 0.005" Example:
(MAH = Magnetic Arc Height & AAH = Adjusted Arc Height)
MAH = AAH
0.0040 = 0.0040 <- new method, new result
0.0045 = 0.0045 <- new method, new result
0.0050 = 0.0050 <- new method, new result
0.0051 = 0.0039 <- new method, same result
0.0055 = 0.0042 <- new method, same result
0.0060 = 0.0046 <- new method, same result
0.0065 = 0.0050 <- new method, same result
0.0070 = 0.0054 <- new method, same result
The method for using an existing curve solver is the avoidance/rejection of any non-adjusted arc heights 0.0050" or less.
I will post again if I receive any new information.
