[QUOTE="canderson, post: 865917, member: 10891"] I have found with the knight armament program. Temperature, humidity, and barometric pressure is enough. Input absolute pressure and the other two. It will give an accurate firing solution. You may have to play with muzzle velocity to get it dead on. Density altitude seems to be a quick reference to the above three factors. I use another app to compute the DA. Then I use the DA in my log book to compare drops with the conditions. My contribution for what it's worth. [/QUOTE]
