Aircraft flight testing is a part of the design evaluation and validation process for new and modified airframes. Many kinds of data, from the attitude of the aircraft to measurements of structural torsion and flight control flutter are necessary for an accurate and complete evaluation of an aircraft design.

There is a trend in experimental aircraft instrumentation towards electronic flight information displays due to their versatility and ability to clearly provide more information in a small space. An attitude indicator of this type needs an electronic signal from a solid-state attitude and heading gyro.

Gyros in aerobatic aircraft experience one of the most mechanically demanding environments. A gyro used for this application must be capable of maintaining accuracy through high G maneuvers and sustained motions.

Piloting an aerial vehicle remotely is a challenging task. There is no pilot in the craft to monitor its position with respect to the ground. Controlling the cost of the vehicle is important, but the cost of a losing an UAV due to inadequate sensors is much higher.

Target drones require a navigation system that will provide accurate heading information to the remote pilot. A low cost, accurate and reusable magnetometer solution is needed to supply data to the digital compass system that supplements the other attitude sensors in the aircraft.
