As the Unmanned Aerial System (UAS) Level Of Automation increases, Mission Planning relevance raises. A mission plan can be defined as all the information needed to reach the assigned goals, and it is composed by several sub-plans. In particular, the mission plan core is represented by the routes. Since the route creation process is very complex, the introduction of route creation and verification algorithms is required. These algorithms enhance also the crew replan performances during the mission execution, and permit to implement autonomous onboard replanning. Furthermore, Planning/replanning processes could also have a key role in the integration of UAS in the civil airspace. According to these considerations, a Mission Planner embedded in the Alenia Aermacchi UAS Ground Control Station has been developed, comprised of advanced planning algorithms. kts Knots LAT Latitude LOA Level Of Automation LON Longitude LOS Line Of Sight MALE Medium Altitude Long Endurance NAS National Airspace System NAVAID Navigational Aids RF Radial to Fix RTI Run Time Input SAR Synthetic Aperture Radar SATCOM Satellite Communications SESAR Single European Sky ATM Research

To integrate UASs in the NAS, an improvement in navigation, planning, communication and 4D trajectory control capabilities is mandatory. A way to obtain this enhance is to adopt a Flight Management System. A FMS for an UAS has some differences with respect to one for a manned aircraft, in terms of architecture and performed functions. In particular, from HMI point of view, the specific UAS human factor issues shall be added to the current manned FMS interface lacks. Starting from these considerations, a new FMS HMI for the Alenia Aeronautica TCS has been developed, using as data entry devices two touch screens.
