Imagine you could replace your obsolete flight data system with a low size, weight and power (SWaP), rugged FDAU, and that it could acquire data from a myriad of modern (and not so modern) analog and digital interfaces with minimal development effort.

Avionics integrators with this ability, dramatically mitigate obsolescence and maintenance risks for their platforms. The resulting reduction of recurring and non-recurring costs help aircraft assets to remain economically viable into the future.

These capabilities and benefits are made possible with Curtiss-Wright rugged mount FDAU solutions. Each LRU is built using a standard catalog of 100+ modular interfaces and pre-configured by our applications integration team. Since all components are off-the-shelf, the non-recurring effort is just related to configuration capture, resulting in a very affordable solution for small fleet operators.

Rapid Development Flow for FDAU

Flight Data Acquisition Unit Flow

Note that Curtiss-Wright only support this approach for DAL-D or DAL-E products and, for large scale projects, the final design and form factor can be modified to optimize weight and cost.
