example 1
[0145] Example 1: Demarcation of control areas under the runway departure procedure of an airport
[0146] Part of the flight segment corresponding to the runway departure procedure is a curve (there is a turn when the flight takes off). The corresponding flight segment in this example s ∈ [0, 10000] is:
[0147]
[0148]
[0149] z(s)=0.05s
[0150] This flight segment describes the turning angle along a circular arc with a radius of 6KM after take-off 2KM Then continue to fly in a straight line. In this example, the parameter of the collision risk zone can be taken as d l = d r = 283.887, d z = 133.5.
[0151] Suppose h = 120 meters, s 1 =10000 meters, at this moment, the boundary nplane(s of the inner core area of the control area 2 ) corresponding parameter s 2 Satisfy:
[0152] z(s 2 )=h+d z =120+133.5=253.5
[0153] Since the gradient k=0.05 corresponding to the flight segment, so
[0154]
[0155] The control area kernel area nfz(10000) is th...
example 2
[0187] Example 2: Designation of the control area under the approach procedure of an airport runway
[0188] This example gives an example of the instrument approach procedure of Chongqing Jiangbei Airport RWY02R, the flight is in the final approach segment is a straight line, and the horizontal velocity v can be known according to the information of the instrument approach chart x =93.05m / s, v y = 0m / s, v z =4.9m / s, the descent gradient of the aircraft during the approach phase is
[0189] flight segment s ∈ [0, 10000] satisfies the condition:
[0190] x(s)=s
[0191] y(s)=0
[0192] z(s)=k×s
[0193] Its collision risk zone parameter is d l = d r = 283.887, d z =129.615
[0194] Suppose h = 120 meters, s 1 =10000 meters, at this moment, the boundary nplane(s of the inner core area of the control area 2 ) corresponding parameter s 2 Satisfy:
[0195] z(s 2 )=h+d z =120+129.615=249.615
[0196] Since the gradient k=0.0526 corresponding to the flight seg...
