But only sights 2 and 11 were an equal pair, there were no other pairs except for the four sights right around LAN. The reason that you use the pair that has the greatest separation in time is due to the rate of change in altitude near LAN. it changes very slowly at LAN and then more and more rapidly the farther away from LAN. This allows a more accurate determination of LAN by averaging those two times. When the change is slow, the accuracy is lost in the noise of the observation. gl --- On Wed, 11/30/11, Mike Burkes <m_burkes@msn.com> wrote:
