Detailed Description
The invention is described in further detail below with reference to the drawings and the specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the description of the embodiments of the present invention, an airport is understood to be any location and place where an aircraft may take off or land, including, but not limited to, civil aircraft, military aircraft, and other manned aircraft.
Fig. 1 is a schematic diagram of an aircraft flight scene provided in an embodiment of the present application. Referring to fig. 1, an aircraft has a predetermined flight plan one: the aircraft lands from a take-off airport to a direct-flight target airport; flight plan two: the aircraft takes off from the take-off airport, lands through the transfer airport, and takes off from the transfer airport to the target airport for landing; flight plan three: the aircraft takes off from the take-off airport, flies to the upper part of the target airport to hover or to hover in the flight path, and lands after hovering for a period of time (not shown in the figure); flight plan four: the aircraft takes off from the airport and goes to the target airport without landing or to the point A between the two airports, and changes to the flying preparation and landing airport.
First, in an ideal case, the aircraft performs a flight plan-the landing of a target airport from a take-off airport is desired by passengers and airlines. However, when the aircraft flies from the take-off airport to the target airport for a certain time, the target airport does not meet the landing condition due to weather reasons after a certain time, and the transfer airport meets the landing condition from the take-off airport to the transfer airport, the second flight plan can be executed at this time, the aircraft flies from the take-off airport, lands through the transfer airport, stays for a certain time, and lands from the transfer airport to the target airport. And because of the variability and uncertainty of weather conditions, the airplane needs a certain time to fly from a take-off airport to a target airport, and the situation that the target airport does not meet the landing condition due to the weather conditions after a certain time exists, at the moment, the airplane can execute a third flight plan or a fourth flight plan.
The invention relates to a method for determining a flight plan, which is used for improving the seating satisfaction of passengers and is described below.
Fig. 2 is a flowchart of a flight plan determining method according to an embodiment of the present invention. Referring to fig. 2, a flight plan determining method provided by an embodiment of the present invention includes:
calculating the route flight time T1 from a take-off airport to a target airport when the aircraft takes off, acquiring the weather condition of the target airport after the T1 time, and executing a flight plan I by the aircraft if the weather condition of the target airport after the T1 time meets the landing condition of the aircraft; if the weather condition of the target airport after the time T1 does not meet the aircraft landing condition, predicting the weather condition in a time period T2 after the time T1, and if the weather condition in the time period T2 after the time T1 meets the aircraft landing condition, executing a flight plan III by the aircraft; if the weather condition in the time period T2 after the time T1 does not meet the aircraft landing condition, acquiring the predicted time T3 of the weather condition of the target airport meeting the aircraft landing condition, and if the predicted time T3 is greater than the preset flight time, delaying the aircraft take-off; if the predicted time T3 is not greater than the preset flight time, judging whether the second flight plan is selected to be executed.
In one embodiment, the time period T2 is determined based on the ride satisfaction of aircraft passengers under flight plan three, including but not limited to, based on user surveys and/or big data fits. The passenger of the aircraft continuously descends along with the increase of the waiting time, and under the condition that the weather condition of the target airport does not meet the landing condition of the aircraft after the time T1, the aircraft is still taking off at the take-off airport, and the fuel oil is consumed by the aircraft spiral, so that the fuel oil economy of the aircraft is reduced, but the emotion of the passenger is different in waiting and flying in the airport, and the passenger taking satisfaction can be improved. The seating satisfaction degree of the aircraft passengers under the third flight plan comprises the waiting satisfaction degree of the passengers at the take-off airport and the flying seating satisfaction degree of the aircraft. The long-time waiting passengers can influence the riding experience of passengers, the same long-time airplane flying riding can influence the riding experience of the passengers, and the subjective experience of the two is different, so that the riding satisfaction of the passengers at a take-off airport and the airplane flying riding satisfaction can be more accurately represented.
In another embodiment, the time period T2 is determined according to the riding satisfaction degree of the passengers of the airplane under the third flight plan and the fuel consumption L3 of the airplane spiral, and the fuel consumption L3 of the airplane spiral is the fuel consumption of the airplane spiral above the target airport or in the flight route in the third flight plan; the passenger satisfaction degree of the airplane under the flight plan III comprises the waiting satisfaction degree of the passenger at a take-off airport and the airplane flight riding satisfaction degree; the ride satisfaction function of the aircraft passengers includes, but is not limited to, a determination based on user surveys and/or big data fits. The passenger takes the satisfaction degree to drop along with the increase of the waiting time, under the condition that the weather condition of the target airport does not meet the landing condition of the airplane after the time T1, the airplane still takes off at the take-off airport, such as the long airplane winding time, the fuel cost is inevitably increased greatly, and the passenger takes the satisfaction degree to drop in the airplane winding waiting, therefore, in the embodiment, the time period T2 is preferably determined according to the passenger taking satisfaction degree of the airplane and the airplane winding fuel consumption L3, the passenger taking satisfaction degree of the airplane is considered, the airplane flying economy is considered, and the passenger taking satisfaction degree and the flying economy are comprehensively determined to the time period T2.
In one embodiment, the calculation of the aircraft hover fuel consumption includes the steps of:
firstly, determining that the aircraft fuel filling amount when the flight plan is executed is L1, and then determining that the aircraft fuel filling amount when the flight plan is executed is L2; let the aircraft hover fuel consumption be L3, l3=l2-L1.
The calculation of the fuel filling amounts L1 and L2 of the aircraft is in the prior art, which is calculated according to mileage, load, aircraft parameters and the like, and is not described herein.
Although the aircraft take-off time can be set according to the moment that the target airport meets the landing condition, the weather conditions of some airports are changeable, and the situation that the forecast is inaccurate exists, so that the aircraft can not normally land in the target airport in the time period T2, and if the situation is met, the aircraft goes to the standby airport. That is, the aircraft selectively lands in the time period T2, flies to the target airport to the sky without landing or flies to the point a between the two airports to land, and flies to the standby airport, thereby increasing operability.
Further, whether the second flight plan is selected to be executed or not is judged according to the riding satisfaction degree and the fuel consumption increment of the second aircraft passenger under the second flight plan, and judgment is carried out by adopting a judgment function formula J=A1×P-A2×L, wherein P is the riding satisfaction degree of the second aircraft passenger under the second flight plan, L is the fuel consumption increment of the second flight plan compared with the first flight plan, and A1 and A2 are corresponding weight coefficients.
In one embodiment, for the aircraft passenger riding satisfaction P under flight plan two, consider take-off airport waiting satisfaction, transfer airport waiting satisfaction, take-off airport flight to transfer airport satisfaction, transfer airport flight to target airport satisfaction, p=b1×p1+b2×p2+b3×p3+b4×p4, where P1 is take-off airport waiting satisfaction, P2 is transfer airport waiting satisfaction, P3 is take-off airport flight to transfer airport satisfaction, P4 is transfer airport flight to target airport satisfaction, B1, B2, B3, B4 are corresponding weighting coefficients.
And if the judgment value J calculated by the judgment function is greater than or equal to the set value, executing a second flight plan, namely taking off the aircraft from the take-off airport, landing the aircraft through the transfer airport, and taking off the aircraft from the transfer airport to land on the target airport. If the judgment value J calculated by the judgment function is smaller than the set value, the aircraft takes off and delays.
In one embodiment, when selecting to execute the second flight plan, an aircraft fueling amount L4 is calculated and determined, the aircraft fueling amount L4 is an amount L satisfying the increase in fuel consumption from the take-off airport to the transfer airport, and whether to fueling the aircraft is determined based on the determined aircraft fueling amount L4.
In one embodiment, when the second flight plan is selected, the departure airport waiting time and the transfer airport waiting time are allocated according to the predicted time T3, the time T4 when the aircraft flies from the departure airport to the middle airport and the time T5 when the transfer airport flies to the target airport, so as to improve the passenger satisfaction of the aircraft.
In addition, in the prior art, weather forecast data of a target airport is not sufficiently acquired. For weather prediction in the above embodiment, an aircraft flying in a predetermined range of a target airport is determined, weather prediction equipment carried by the aircraft flying in the predetermined range of the target airport is determined on the basis of the weather prediction equipment of the target airport, and weather conditions of the target airport are predicted by using the weather prediction equipment of the target airport and weather data acquired by the weather prediction equipment carried by the aircraft flying in the predetermined range of the target airport, so that the accuracy of basic weather prediction of the target airport is improved.
The method comprises the steps of dynamically adjusting the preset range, adjusting the radius of the preset range according to weather conditions of an airport, dividing the weather conditions into different grades, and gradually increasing the radius of the preset range along with the grade improvement when the grade is higher and the weather is worse, so that the data processing amount is reduced under the condition of guaranteeing the weather prediction accuracy of the airport.
