Android Phone Center of Gravity Calculator for planes

Here is a free Android Phone CGC (Center of Gravity Calculator) for planes (It can prevent a crash!).

You enter your required CG percentage, measure and enter the tip chord, the root chord and the sweep and it will calculate the position of the center of gravity of an airplane measured back from the leading edge at wing root.

It's free, released as donationware, and is now available on 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)

Now available on the Android Market:

Thanks

I think you must post this in "The Builders Workshop" or "Modeling Science" forums or even in "Electric Plane Talk", there you will get more reaction.

Graham,

Have you tried this application out yet? How accurate is it? Will it save your data?

Thanks!

Before publishing I tested this application extensively, it is accurate to more than 3 decimal places however it won't save your data as it's intended for 'live' once off use.

All it does it calculate the postion of the CG based on the percentage you enter. If the CG is too far back on a plane you WILL crash! Use this the to prevent destroying your plane.
