Methods and devices to measure an angular deflection of an aircraft member. The devices are configured to be attached to the aircraft member. The devices are configured to obtain an orientation of the device about three separate axes. The methods use initial orientation values and dynamic orientation values to calculate an axis of rotation. Using the axis of rotation, the deflection angle can be calculated for the aircraft member.

Method and apparatus for remote angle calibration and measurement

Methods and systems for monitoring an integrity of electrical connectivity between a repair patch and a parent structure include providing the repair patch with an embedded sensor configured to detect electrical conductivity. The repair patch includes a ply of conductive material that overlaps a portion of a conductive layer of the parent structure. A baseline set of sensor data is acquired from the sensor indicative of an electrical connectivity between the ply of conductive material of the repair patch and the conductive layer of the parent structure. One or more additional sets of data may be obtained from the sensor and compared to the baseline set of data to determine an integrity of the electrical connectivity between the ply of conductive material of the repair patch and the conductive layer of the parent structure.
