But what about when you can't support the Size, Weight, and Power (SWAP) requirements of the flight IDM? Host the IDM capability on any available hardware with the IDM/App.

Aligned with the FACE Technical Standard 2.0

Built with Quoit, the IDM/App brings the data-link capabilities of VMF over BFT to any FACE Environment.
