GliderCG is a CoG digital balance device for sailplanes of up to 6Kg able to provide the exact
information of where the CoG is located in our glider by through a screen that also provides
information of the sailplane´s total weight.
Unlike the existing CoG scales based on the balancing of the sailplane on a supporting point,
GliderCG uses the barycenter formula to obtain the precise calculation of our CoG without
having to balance our sailplanes with the risks to the Integrity of them.
Introduction
The condition for Static Equilibrium of the model plane, that is, it is not rotating, imposes the
model weight is splitted in two reaction forces p1 and p2 applied in the supports A and B
respectively, such as their resultant force passes thru the Center of Gravity of the model.
The position of the CoG is calculated by solving the equations:

K is known for the manufacture of the scale.
