Abstract: A vehicle comprising: an user interface (UI); a global positioning system (GPS); an inertial reference system (IRS); and a terrain awareness and warning system (TAWS), the TAWS comprising processing circuitry configured to: receive at least one of: GPS data from the GPS or IRS data from the IRS; determine, based at least in part on the received at least one of the GPS data or the IRS data, whether the vehicle is receiving one or more of a GPS spoofing signal or a GPS jamming signal; and in response to a determination that the vehicle is receiving the GPS spoofing signal or the GPS jamming signal, cause the UI to output a notification indicating that the vehicle is receiving the GPS spoofing signal or the GPS jamming signal.

Abstract: Methods and systems are provided for assisting vehicle operation for collision avoidance. One method involves determining a horizontal adjustment for the vehicle based at least in part on an output from a collision avoidance system and displaying, on a display device, a graphical indication of the horizontal adjustment at a position on the display device with respect to a reference position of a second graphical indication of a current orientation of the vehicle resulting in a distance between the position of the graphical indication and the reference position of the second graphical indication corresponding to the horizontal adjustment. The distance dynamically updates in response to changes to the orientation of the vehicle.

Abstract: A method of predicting performance characteristics of an aircraft including modeling thrust-minus-drag of an aircraft with at least one mathematical model using aircraft specific data and input parameters which define the performance characteristics. Coefficients of the at least one mathematical model are learned over at least one flight. The performance characteristics are predicted as a function of the learned coefficients representative of a combined and non-independent thrust-minus-drag relationship.
