Android Phone Center of Gravity Calculator.
Here is a free Android Phone CGC (Center of Gravity Calculator) for planes.
It will calculate the position of the center of gravity of an airplane
using the tip chord, root chord, sweep and required CG in percent,
measured back from the leading edge at wing root.
It's free, released as donationware, just download the .apk file below
and use Astro File Explorer or Estrongs File Explorer (or equiv.) to
install it. (I'm busy working on getting it onto the Android Market.)
It's pretty intuitive but instructions are behind the 'Instructions' button
Comments and suggestions welcome!
Please try it out and send it to anyone who might be able to use it! (or point them to this post)
