GPS pos. is 32*49.40'N 116*49.80'W 3 LOP paper fix = 32*49.3'N
116*50.7'W
Software check fix = 32*49.25'N 116*49.7'W
I don't have a barometer where I'm at.I used Table A4's 970mb and 40-50*F
column because it was the lowest in the table and Mr. Hebard's
recommendation of 28 in. of merc. approximating 2100 ft.
I use HO-229 or 249 vol.I occasionaly to keep in practice.The N.A. for
corrections.I do pick the Hc slope out of HO-229 for the averageing.I use a
scientific calculater programmed for intercepts.I do have a software program
I use only for checks.
So,I'm still wondering about the effects of the elevation and temp.04-26
same elevation differant temps. and the results were more consistant with
the norm.
