if I found the right index that one says 11.30 something fro about 7.28 . Thats about what I got off another web site a while back but I questioned it's accuracy. I hope that is true..
Thanks Lance, and again sorry for getting off topic it just made me wonder about the conversions. Lance what is the alt at CV ??? close to 0 ? PM me no need to clutter this thread any more. Thanks

I posted a bunch of info I had on density altitude calculations here: http://www.arkansaspontiacs.org/apaf...opic.php?t=414

Included are links for weather info such as temp, baro, and dew point. One site keeps a history of weather on the site. Another can be used to determine your tracks elevation, then a link for a DA calculator and finally a chart for time adjustment.

Hope this helps.
