Custom Indicators & Instruments

The design and production of precision avionics instruments has become a highly specialized capability at Jewell Instruments. Our engineering team routinely employs new materials, configurations, and concepts to achieve customer-specified combinations of weights, size, readability, and ruggedness.

In any aircraft instrument system, reliable performance depends on avionics-instruments. Our avionics-instruments present information accurately, simply, and intelligently. Jewell Instruments engineers know that their designs must accomplish system objectives regardless of environment — vibration, rapid attitude change, or other influences. Our expertise in custom-built next-level assemblies spans across years of experience and hundreds of aircraft.

JEWELL Flight Directors (described below) is an example of our capabilities. They illustrate the advanced design concepts employed by our engineers. Whatever your needs may be, our engineering know-how is ready to serve your needs. (View our Partnership Manufacturing Brochure)
