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.
Claims20
A method for checking the fuel quantity of a vehicle based on vehicle performance, comprising the steps of:
- a) predicting vehicle performance based from a plurality of vehicle related input parameters including assumed fuel quantity to provide predicted vehicle performance data;
- b) measuring actual vehicle performance from a plurality of vehicle sensor systems to provide measured actual vehicle performance data;
- c) comparing said predicted vehicle performance data with said measured actual vehicle performance data to provide an indication as to whether the vehicle is operating within a selected tolerance of the prediction;
- and,
- d) providing an alert message if the vehicle is determined to be operating outside of said selected tolerance of prediction.
A flight management system for an aircraft vehicle, comprising:
- a) a flight management computer configured to:
- i) predict vehicle performance based from a plurality of vehicle related input parameters including assumed fuel quantity to provide predicted vehicle performance data;
- ii) measure actual vehicle performance from a plurality of vehicle sensor systems to provide measured actual vehicle performance data;
- iii) compare said predicted vehicle performance data with said measured actual vehicle performance data to provide an indication as to whether the vehicle is operating within a selected tolerance of the prediction;
- and,
- iv) provide an alert message if the vehicle is determined to be operating outside of said selected tolerance of prediction;
- and,
- b) an aircraft performance database operatively connected to said flight management computer for providing input to predict said vehicle performance.
A method for checking the fuel quantity of a vehicle based on vehicle performance, comprising the steps of:
- a) comparing a predicted vehicle performance data based on a plurality of vehicle related input parameters including assumed fuel quantity and a measured vehicle performance data based on input from a plurality of vehicle sensor systems;
- and,
- b) providing an alert indicative of an assumed fuel quantity error to a user in response to the predicted vehicle performance data and the measured vehicle performance data differing from one another by a predetermined threshold.
