Abstract

A calibration system for aircraft control surface actuation includes an inclinometer coupleable to an aircraft control surface. The inclinometer is configured to provide measurement data of an inclination value corresponding to an angle at which the surface is deflected. The system includes an adapter with a wireless transmitter module and an interface connector connected to the inclinometer. The adapter is configured to receive and wirelessly transmit the measurement data. The system includes a wireless receiver device and a computing device connected thereto to receive the measurement data. The computing device is configured to determine if the inclination value differs by more than a predetermined amount from a directed deflection angle for the surface. The computing device is also configured to communicate an adjustment amount to a controller configured to direct deflection of the surface, based on the difference between the measured inclination value and the directed deflection angle.
