1. A control surface controller force measurement system for an aircraft, comprising:
a control surface interface having a range of motion for providing pilot input mechanical force for positioning at least one
aerodynamic control surface on an aircraft;
a first mechanical link being pivotable about a first pivot and interconnected to the control surface interface for transferring
mechanical force applied to the control surface interface;
a second mechanical link interconnecting the control surface interface to the first mechanical link, the second mechanical
link being pivotable with respect to the control surface interface at a second pivot; and
a force transducer for transducing the mechanical force applied to the control surface interface to a representative electrical
signal, the force transducer having first and second portions and being operably interconnected at the first portion to the
first mechanical link and operably interconnected at the second portion to the second mechanical link and the interconnections
to the first and second portions being independent of the second pivot.
