Your custom design
in half the time, at half the cost
Flex® is a blank slate for designers, avionics, and systems engineers. It’s the only certified all-in-one controller and data converter with glass display functionality. Flex offers a custom behind-the-panel interface or a fast and easy replacement for legacy displays beyond economical repair. Flex receives ARINC 429, analog, discrete, frequency, temperature, absolute and differential pressure data to meet the specific needs of any pilot and any mission.
Expect Fast
Go from concept to cockpit in 30 days. Flex is ready and waiting for your custom design. Its base hardware and software are already TSO certified and RTCA qualified to Design Assurance Level A. Building your custom unit on this certified foundation speeds up your product development process and reduces your certification timeline by up to two years.
Expect Easy
Eliminate the complex product development process. With 18 programmable inputs and outputs, 2 pressure ports, and internal inertial sensors, the applications for Flex are virtually limitless, whether in or behind the panel. When using the unit's glass display functionality, you can easily customize the configuration, user interface and graphics. You’ll streamline integration with the standard, 2-inch size and keep life simple with a single, push-and-turn control knob, and field-upgradeable software.
Expect Affordable
Cut cost, not corners. Design a fully certified, custom data solution at a price you can afford. Flex NRE and certification costs are exceptionally low, starting at only $15K. Now, you can leverage leading-edge technology and a game-changing product development process to save up to $1M, per custom unit.
