There are more factors than just Altitude and Temperature

<p>Most people commonly believe there are only two factors related to determining density altitude: field elevation and temperature.&nbsp; The belief that these are the only factors stems from the age-old use of the &ldquo;density altitude chart&rdquo; that every pilot encounters in textbooks, on tests, and in aircraft performance manuals.&nbsp; </p><i><p>This chart doesn&rsquo;t tell the whole story, a pilot also needs to determine the effect on density altitude of humidity and atmospheric pressure.</p></i><p>In reality, humidity and air pressure also impact density altitude, however not to the extent of temperature and field elevation.&nbsp; Combined however the impact of these two factors can be significant.</p><p>Today, many of the electronic flight calculators include functions for calculating the actual density altitude.&nbsp; Additionally, there are several web sites with complete density altitude calculators such as the one created by Richard Shelquist that can be found at:&nbsp; </p><p><a href="http://wahiduddin.net/calc/calc_da.htm">http://wahiduddin.net/calc/calc_da.htm</a></p> 9 application/xml false density altitude humidity leadville airport mountain flying temperature Density Altitude http://wahiduddin.net/calc/calc_da.htm Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.18) Gecko/20110614 Firefox/3.6.18 127.0.0.1 127.0.0.1 itechnologydesign 74.112.18.33 false true false false true 81303 blog blogsite/MountainCFI/web
