Oil filling quantity warning method

Abstract

The invention discloses an oil filling quantity alarming method of an oil receiver, which comprises the following steps of: acquiring airport information and current position information, current residual oil quantity and external store information, and acquiring current position information of an oil dispenser and residual oil filling quantity of the oil dispenser; calculating the maximum range circle of the oil receiver according to the current position information and the airport position information, and calculating the oil filling quantity required by the oil receiver from the nearest airport according to the external store information, the current position information and the airport position information; displaying the position of the airport, the current position of the oil receiver, the maximum range circle of the oil receiver, the required oil filling quantity of the oil receiver, the current position information of the oil dispenser and the residual oil filling quantity of the oil dispenser on a display device. According to the method, the maximum range circle which can be reached by the airplane by using the existing oil quantity is calculated and displayed in real time, so that a pilot can more intuitively know the range state of the airplane in real time.

Description

technical field [0001] The application belongs to the technical field of aircraft avionics system design, and in particular relates to a method for warning the quantity of refueling fuel. 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, it is often necessary to refuel in the air to reduce the risk of returning to the landing. 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 air...

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
