Abstract: A system and method for checking the fuel quantity of a vehicle based on vehicle performance includes predicting vehicle performance based from a number of vehicle related input parameters including assumed fuel quantity to provide predicted vehicle performance data. Actual vehicle performance is measured from a number of vehicle sensor systems to provide measured actual vehicle performance data. The predicted vehicle performance data is compared with the measured actual vehicle performance data to provide an indication as to whether the vehicle is operating within a selected tolerance of the prediction. An alert message is provided if the vehicle is determined to be operating outside of the selected tolerance of prediction.

Abstract: Present novel and non-trivial system, device, and method for generating a temporary, pop-up, location-dependent clock to the pilot of an aircraft. A clock generator may be configured to retrieve approach procedure data representative of waypoint location such as the location of a final approach fix; receive navigation data representative aircraft location information; determine the passing of the waypoint inbound to the applicable airport; and perform one repetitive clock operation of a plurality of repetitive clock operations upon the passing of the waypoint, wherein an image data set is generated and provided to one or more display units. The image data set could be representative of (1) a pop-up timer displaying a counting down of time from the manually-initialized, estimated time, or (2) a pop-up stopwatch displaying a counting up of time when the estimated time is not manually initialized.
