[QUOTE="lever-hed, post: 786114, member: 11667"] [FONT=Arial][SIZE=3]OK so ‘density altitude’ is simply the standard barometric pressure at the given altitude(s), I understand this part (shown in the chart in my previous post). Then the ‘real pressure’ or actual pressure is going to be plus/or minus that number depending on the particular weather system in the area. So if you are entering DA that simply gives you a standard pressure (and corresponding air density) irrespective of the weather system at your position, and, contrarily, if you are entering [I]actual[/I] altitude, pressure, temp + humidity(from a kestrel for ex.) that is obviously better than just entering DA. So, essentially, your cards are only going to reference the standard pressure/air density for each elevation, which is simply your baseline, as I understand. Temperature and humidity will also have an affect on air density. Thanks for the good explanation/rendition.. Lever [/SIZE][/FONT] [COLOR=#1F497D][FONT="] [/FONT][/COLOR] [/QUOTE]
