1976 Standard Atmosphere
(0-86 km)

  This site now uses a Flash emulator called Ruffle. This is all done automatically on our server (no need to configure or install anything on your part). Note: Due to lack of keyboard and mouse pointer, MAY NOT BE USABLE WITH iPad or iPhone. Hasn't been tested on iPads with keyboard and mouse pad.  

Instructions: Select the desired property from the pulldown menu for the desired graph, and select the desired unit. The Z scale units can also be chosen using the small box on the left of the axis. If you wish to compare properties against each other enable Graph 2, and/or Graph 3. When choosing more than one graph the grid is turned off to avoid clutter.

168 graphs!
27 properties can be graphed against Geometric Altitude. Different units can be chosen for the graphs. This is the equivalent of having 168 graphs for standard atmosphere.
