A kind of warning method of refueling fuel quantity

Abstract

The present application discloses a method for warning the refueling quantity of a refueling machine, which includes: acquiring airport information and current location information, current remaining fuel quantity, information on external storage items, and obtaining the current location information of the refueling machine and the remaining refueling quantity of the refueling machine; Calculate the maximum voyage circle of the oil receiver according to the current position information and the airport position information, and calculate the refueling amount required by the oil receiver from the nearest airport according to the store information, current position information and airport position information; display the airport on the display device Location, the current position of the receiver, the maximum voyage circle of the receiver, the amount of refueling required by the receiver, the current position information of the tanker, and the remaining refueling capacity of the tanker. The application calculates and displays the maximum voyage circle that the aircraft can achieve by using the existing fuel quantity in real time, which helps the pilot to understand the voyage status of the aircraft in real time more intuitively.

Description

technical field [0001] The present application belongs to the technical field of aircraft avionics system design, and in particular relates to a fuel oil quantity warning method. Background technique [0002] At present, the aircraft generally only has the remaining fuel warning, that is, the warning is issued when the remaining fuel of the aircraft is less than the set warning fuel, and once the warning is issued, aerial refueling is often required to reduce the risk of returning to the airport. However, at present, the aircraft can only provide a display of the remaining fuel, and the pilot can only know how much fuel is left, but cannot intuitively know how much fuel needs to be added to the nearest airport. In order to reduce the flight risk, a conservative strategy will be adopted, that is to add a lot more oil than the required amount of oil. On the one hand, the excessive amount of refueling will cause fuel waste and increase the flight cost. On the other hand, when m...

But at present, the aircraft can only provide a display of the remaining fuel, and the pilot can only know how much fuel is left, and cannot intuitively know how much fuel needs to be added to the nearest airport. In order to reduce the flight risk, a conservative strategy is adopted, that is, to refuel much more than the required amount of fuel. On the one hand, too much refueling will cause fuel waste and increase flight costs. On the other hand, when multiple aircraft need refueling at the same time , it is difficult to make full use of limited air refueling resources (usually only one tanker is equipped in the mission area), and it is difficult to configure an optimal refueling plan for each aircraft; secondly, it is also difficult for pilots to know the remaining fuel on board in real time How far can fly, often need to allocate part of energy to pay attention to the remaining fuel value and estimate and judge through experience in real time, but in a tense environment, it is difficult to take all into account while performing high-intensity mission operations, so it is necessary to design a A method that can visually display the maximum voyage circle that the aircraft can achieve with the existing fuel quantity and can give a refueling warning and display the reference refueling amount in time when refueling is required in the air
