The emerging role of Unmanned Aerial Systems (UAS) for both military and civil
operations depends on the ability to gain unrestricted access to national airspace. One of
the key issues that must be resolved to open up the skies for UAS is to be able to coexist
safely and effectively with current manned operations in the national and international
airspace. This includes several functions all related to avionics. Future UAS systems will
perform autonomous mission management, contingency management, collision avoidance, intelligent system health monitoring based on a reliable flight control system platform.
