Abstract: Various embodiments of the teachings herein include methods for operating a vehicle. The methods may include: accessing a travel plan identifying an intended destination and a predicted state of the energy store including a predicted value for a parameter of the energy store upon arrival; determining an instantaneous location; determining a predicted value for the first operating parameter based on the location and the travel plan; measuring an instantaneous value for the parameter; calculating a first deviation between the predicted value and the instantaneous value; calculating an expected final value for the parameter upon reaching the intended destination based on the instantaneous value; calculating a second deviation between the predicted final value and the expected final value; indicating to an operator both of the deviations; and executing one or more changes to controls of the drive system in response to at least one of the two deviations.

Abstract: The present invention relates to a method for monitoring the integrity of an inertial measurement assembly (10) of an aircraft, the measurement assembly comprising at least one high-grade measurement unit (20); and at least two low-grade measurement units (30, 40); wherein each of the measurement units (20, 30, 40) comprises a sensor unit (22, 32, 42) and a processing unit (24, 34, 44) operatively coupled to the respective sensor unit (22, 32, 42), wherein the respective sensor units (22, 32, 42) measure accelerations and angular rates of the aircraft and provide raw data based on said measurements; wherein the respective processing units (24, 34, 44) process the raw data provided by the sensor units (22, 32, 42) and provide processed data reflecting the velocity and/or attitude of the aircraft; the method comprising: at a sensor monitoring unit (50), receiving the raw data output by each of the sensor units (22, 32, 42) and evaluating according to at least one predetermined criterion whether the raw data of

Abstract: System 10 for navigating an aircraft 12, comprising a flight planning system 14 configured to prepare a set of at least three different trajectories for a flight from a departure point to a destination point, a flight verification system 16 configured to verify each trajectory of the set of trajectories, an onboard flight management system 26 to be installed at an aircraft 12 and having a storage unit 28 for storing the set of trajectories, wherein the flight management system is configured to select one of the trajectories from the set of trajectories as an active trajectory for a current flight of the aircraft, wherein the flight management system 26 includes a replanning unit 30 configured to change, during the current flight, the active trajectory by selecting a second trajectory from the set of trajectories as the active trajectory for the current flight, such as to continue the current flight based on the second trajectory t.
