14 AEROSPACE / WHITE PAPER CONNECTING THE FUTURE OF FLIGHT device mass and volume are greatly reduced. This approach helps designers meet design and center-of-gravity (COG) constraints by simplifying how components integrate into the airframe. It also enhances reliability by reducing repair points for connections and cards. ARINC 836A Embedded systems, edge computing, and truly distributed architecture are combining to push IMA to the next level. The ARINC 836A standard supports this effort by establishing a mini modular rack principle (MiniMRP) for avionics packaging. The advantages of MiniMRP for UAM avionics include: • Significantly reduced size with as much as 40% smaller packaging and 60% weight savings • Enhanced flexibility and simpler configuration with a less costly commercial- off-the-shelf (COTS) selection approach • Secure attachment of modules and boards with robust latches and interconnects PERFORMANCE By implementing edge intelligence in miniaturized electronics packaging, the avionics designer can implement navigation, communications, and other intelligent functions locally without being wired back to a central microcomputer. With edge computing, processing occurs at sensor or control nodes to enable nearly instant decision-making in support of autonomous control. Embedded-edge intelligence can act as if it is a Remote Interface Unit on the airframe extremity that converts sensor signals into ARINC 429-compliant digital packets transmitted over fiber optics to mission computers. EWIS engineers benefit from more bandwidth for monitoring and flight-system control— while enjoying size and weight reductions to minimize disk loading and optimize battery life. Finally, edge intelligence can also function as an Internet of Things (IOT) device that connects to the "cloud" for high-order functions, such as predictive analytics.
