[QUOTE="Mikecr, post: 74027, member: 1521"] Your program is assuming pressure at altitude of 29.53, instead of 24.923(std conditions at altitude). Nothing wrong with this if you measured and appropriately entered 29.53 at 5000'. Higher pressure, more drop. When you enter 29.53 @ 0', this is your pressure at entered altitude. If thats your measured absolute pressure, then your right, you should leave altitude at zero. Even if your standing 5000' up. [/QUOTE]
