Abstract: Aerial navigation is disclosed. A system can detect a difference between forces applied to a plurality of ground contact points of an aerial vehicle taxiing on a ground surface. The system can determine an adjustment to a vertical component of a thrust. The thrust can be produced by at least one of a rotor or a propeller of the aerial vehicle to reduce the difference between the forces applied to the plurality of ground contact points of the aerial vehicle. The system can generate a control output to cause the at least one of the rotor or the propeller to adjust the vertical component of the thrust to reduce the difference between the forces.

Abstract: Systems and methods for controlling an aircraft to hold altitude using GPS altitude readings. One example system includes a GPS inertial navigation system, an altimeter, a human machine interface, and one or more electronic processors coupled to the GPS inertial navigation system, the altimeter, and the human machine interface. The one or more electronic processors configured to receive, from the human machine interface, a user input selecting a reference altitude. The one or more electronic processors configured to receive, from the altimeter, a current altitude for the aircraft. The one or more electronic processors configured to: when the current altitude does not exceed an altitude threshold, operate the aircraft in an altimeter altitude hold mode based on the reference altitude; and when the current altitude exceeds the altitude threshold, operate the aircraft in a GPS altitude hold mode based on the reference altitude using the GPS inertial navigation system.

Abstract: A computer-implemented method and system for controlling an aircraft based on detecting and mitigating fatiguing conditions and aircraft damage conditions is disclosed. According to one example, a computer-implemented method includes detecting, by a processing system, a health condition of a component of the aircraft. The method further includes determining, by the processing system, whether the health condition is one of a fatigue condition or a damage condition. The method further includes implementing, by the processing system, a first action based at least in part on determining that the health condition is a fatigue condition to mitigate the fatigue condition. The method further includes implementing, by the processing system, a second action based at least in part on determining that the health condition is a damage condition to mitigate the damage condition.
