I would like to help.

This website gives you hour by hour weather history:

This site gives your Density Altitude according to the weather conditions:

This site gives you a estimate E.T. if you were running at sea level with ideal weather conditions:

http://www.supermotors.org/vehicles/...ed_on_altitude

This one gives you the track altitude:

Edit:
Thanks, its correct now.

 

your estimate e.t. link is for finding density altitude. i found it though and those 4 links could definately be a sticky. i especially like the my et link. i just learned alot about density altitude and how it can help/hurt your slips. the the rest of the links help you get the info to punch into your my et data. cool beans
