Unmanned Cargo Aircraft is the Way of The Future for Air Delivery Raymond J. DeMarco Embry Riddle Aeronautical University Worldwide Abstract A good argument can be made that unmanned cargo aircraft save the air cargo industry billions of dollars while filling a gap in the cargo shipping industry. When Federal Aviation Administration (FAA) regulations permit large unmanned aircraft to fly in the national airspace system (NAS), shipping companies will seek a new way of delivering materials through the air. A great advantage for Unmanned Cargo Aircraft (UCA) design is cost efficiency due to reduced fuel consumption and lesser crew cost. Safety of property and people are of greatest concern along with information, command and control security. ADS-B is a major contributor to sense and avoid technology requirements to allow manned and unmanned aircraft to work in unison and maintain separation. Avoidance will play a major role for safety and ul...
