Abstract: A system and method for UAV power management includes a processor for monitoring power loads in the UAV and switching power sources based on a load profile in real time. The system may monitor flight phases or issued commands to proactively switch power sources in anticipation of an eminent change in the load profile.

Abstract: A fixed-wing UAV includes an automatically loitering routine to allow a single user to launch the vehicle. In a takeoff mode, the UAV follows a predefined routine to climb to a predetermined altitude and maintain a substantially constant distance from a controller. Once control inputs are received from the controller, the automatically loitering routine disengages. During a landing sequence, the UAV is placed into an autonomous landing mode. The UAV initiates a glide path to a desired landing position; at a predetermined altitude, the UAV executes a reverse thrust operation to quickly decelerate at a touch down point. The UAV then executes landing maneuvers to safely touch down.
