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. -----Original Message----- From: Zorbec Legras [mailto:legras@MAD.SCIENTIST.COM] Sent: Thursday, May 01, 2003 23:01 To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: Re: Table A4 + elevation? ----- Original Message ----- From: "Royer, Doug"Date: Thu, 1 May 2003 12:59:18 -0700 To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: Table A4 + elevation?
