Problems solved by technology

In addition, a large number of studies assume that the flight error of the aircraft satisfies a fixed distribution within a flight segment, but it facilitates the calculation of the collision risk assessment and at the same time has a certain loss in the accuracy of the risk assessment, and thus cannot guarantee the rationality of the designation of the collision risk area

Embodiment example

[0101] Implementation case: Collision risk zone designation under the approach procedure of an airport

[0102] Flight on final approach segment is a straight line. This example gives an example of the instrument approach procedure of Chongqing Jiangbei Airport RWY02R. According to the information on the instrument approach chart, s 0 = 10000 meters, horizontal velocity v x = 93.05 m / s, v y = 0 m / s, v z =4.9 m / s, so it can be seen that the descent gradient of the aircraft during the approach phase is old flight segment s ∈ [0, 10000] satisfies the condition:

[0103] x(s)=s

[0104] y(s)=0

[0105] z(s)=k×s

[0106] Assume that the lateral error and vertical error of the flight satisfy a normal distribution with a mean of zero, namely:

[0107] ε y (s)~N[0,δ 0 (s)]

[0108] ε z (s)~N[0,δ 1 (s)]

[0109] Assuming the standard deviation satisfies:

[0110]

[0111]

[0112] where b 0 =0.02,b 1 =0.01, take the size of the aircraft as: λ y =50,λ z = 15...

Abstract

The invention provides a method for demarcating a collision risk area of a flight route segment, and the method comprises the steps: S1, demarcating the geometrical characteristics of the route segment according to the characteristics of route segment data; S2, establishing a collision risk area boundary model according to the route segment curve and the collision risk probability e; S3, limitingthe collision risk area to be the minimum area with the boundary meeting the constraint condition; and S4, calculating parameters corresponding to the risk boundary. The division method provided by the invention provides a guarantee for the operation safety and efficiency of the civil aircraft in the ultra-low-altitude airspace around the airport, and provides a technical support for realizing refined operation management of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of air traffic control, in particular to unmanned aerial vehicle air traffic operation management. Background technique [0002] In recent years, the scale of the civilian UAV market has continued to expand. UAVs are easy to manufacture and easy to obtain, making UAVs widely used. This has also accompanied the emergence of various risks hidden in the operation of UAVs, among which the most typical The biggest risk is that drone flights interfere with the normal take-off and landing of flights at civil aviation airports. In July 2014, a civil airliner that was preparing to land at Heathrow Airport in London almost collided with a black flying drone. The accident investigation was determined by the authorities as a "serious risk of collision" with a grade of "A"; in 2016 In April, a civil airliner carrying 132 passengers and 5 crew members collided with a remote-controlled drone on the way from Geneva to Lond...
