Your custom display
in half the time, at half the cost
The Flex® Custom Function Display is a blank slate for designers, avionics, and systems engineers. It’s the only controller, data converter and custom display, all-in-one. Flex receives and displays 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 display 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. You’ll easily customize the configuration, user interface and graphics of your Flex display. The applications are virtually limitless with 18 programmable inputs and outputs, 2 pressure ports, and internal inertial sensors. 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 function display at a price you can afford. Flex NRE and certification costs are exceptionally low, starting at only $10K. Now, you can leverage leading-edge technology and a game-changing product development process to save up to $1M, per custom display.
