Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation management, and particularly relates to a method, device and system for triggering wake turbulence interval timing based on flight track situation at takeoff. Background Art

[0002] The tower control automation system (hereinafter referred to as the tower system), with the advanced surface movement guidance and control system (A-SMGCS) and the electronic progress strip system (EFS) as the core, has functions such as surveillance data processing, alarm processing, path planning, lighting guidance, flight data processing, recording and playback, etc. The tower system is a control and command system applicable to the air traffic control tower department, integrating the functions of multiple systems such as air traffic control automation required for tower control, advanced surface movement guidance, tower electronic progress strip, digital air traffic control, collaborative departure, meteorology, lighting control, etc., and can simultaneously provide tower controllers with air and surface situation displays and various flight and surface conflict alarms.

[0003] The tower electronic progress strip system is an important system for the air traffic control tower department to implement ground command. It is an integrated system that provides the ground status of inbound and outbound aircraft and various control instruction management for tower controllers by processing flight plans and dynamic telegrams.

[0004] In order to prevent aircraft from approaching dangerously or colliding in the air, the International Civil Aviation Organization has made detailed regulations on various intervals during flight, including various stages such as en-route flight, airport terminal area flight, approach and departure flight, etc. Wake turbulence interval is a very important flight interval among them. When two aircraft take off continuously, in order to ensure the safety of the aircraft (preventing the wingtip vortices generated at the wingtips of the preceding aircraft from affecting the flight of the following aircraft), according to regulations, it is necessary to have an interval of 1 - 3 minutes, mainly depending on the wake turbulence situation of the preceding and following aircraft types. Because too long an interval will also affect the runway operation efficiency. Especially at airports with a large number of flights, it will cause delays in departing flights and affect the normal takeoff rate of flights. Therefore, how to accurately and safely master the interval between departing aircraft is particularly important.

[0005] Currently, in the tower control automation system or the tower electronic progress strip system, the minimum safe wake turbulence interval time parameter for two aircraft to take off continuously is predefined. When the tower controller manually operates the electronic progress strip in the TKF (takeoff) or ROL (taxi) state, the system interface starts timing and displaying, and the displayed wake turbulence timing time is different according to the different preceding and following aircraft types. When the timing reaches the minimum safe wake turbulence interval time for two aircraft to take off continuously, the timing stops or there is a color reminder on the interface. At this time, the controller can issue a takeoff instruction to the next aircraft about to take off, and the ultimate goal is to ensure that two continuously taking off aircraft maintain a sufficient safe wake turbulence interval.

[0006] The above traditional technology has the following disadvantages:

[0007] Relying on the manual operation of the tower controller to trigger the start time of the takeoff wake vortex interval is inaccurate. There is usually a time difference of 20 to 40 seconds. Referring to the takeoff wake vortex interval standard, the maximum interval is 180 seconds between the leading large aircraft and the trailing light aircraft, and the minimum interval is 80 seconds between the same type of aircraft in front and behind. From this, the error rate is calculated to be between 11% and 50%. At the same time, the end time of the corresponding timing is also inaccurate, ultimately resulting in inaccurate control of the minimum safe wake vortex interval time between these two continuously taking off aircraft. If the time is too long, the runway utilization efficiency is reduced; if the time is too short, the flight safety of the aircraft is affected.

[0008] The reasons for the above disadvantages are:

[0009] The start time of the takeoff wake vortex interval is completely triggered by the manual operation of the tower controller when the status of the electronic progress sheet is TKF (takeoff) or ROL (taxiing). In most cases, the tower controller needs to visually observe the runway situation and will not be timely for operating the status of the progress sheet. Therefore, there will be situations of premature operation or delayed operation. Summary of the Invention

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] It should be understood that when used in this specification and the appended claims, the terms "comprises" and "comprising" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0039] In the process of air traffic control and command, the start time of the takeoff wake turbulence interval timing is determined when the visual aircraft's moving wheels are observed and the aircraft is in the process of accelerating taxiing.

[0040] The tower control automation system has the function of processing and displaying the track situation, so it can accurately identify the scenario where the aircraft has its wheels moving and is accelerating along the runway according to the corresponding logic.

[0041] Specifically, the tower control automation system can determine whether the current target aircraft (i.e., the airplane) is in the scenario where its wheels are moving and it is accelerating along the runway according to the following logic:

[0042] (1) The current speed of the target aircraft ≥ 5 m / s; this value is an empirical value of the staff and allows for certain adjustments;

[0043] (3) The acceleration of the target aircraft in three consecutive cycles ≥ 5 m / s 2 ; this value is an empirical value of the staff and allows for certain adjustments;

[0044] If the target aircraft simultaneously meets the above conditions (1) and (2), the takeoff wake interval timing is immediately triggered.

[0053] If the cycle count is greater than or equal to the cycle threshold, automatically trigger the takeoff wake interval timing.

[0054] Compared with the prior art, the method for triggering takeoff wake turbulence interval timing based on flight track situation provided by the embodiments of the present invention mainly relies on the flight track situation to accurately trigger the takeoff wake turbulence interval timing, and then can accurately obtain the end moment of the takeoff wake turbulence interval timing, which brings the following advantages:

[0055] (1) Improve the flight safety of aircraft: More accurately mastering the wake turbulence interval of the takeoff aircraft can ensure that the interval between two takeoff aircraft meets the operating safety standards.

[0061] Specifically, the trigger module is specifically configured to:

[0062] In the current period, obtain the target aircraft according to the analysis of the flight track data;

[0063] Obtain the current speed of the target aircraft from the flight track data;

[0064] If the current speed is greater than or equal to the speed threshold, and compared with the previous period, the acceleration of the target aircraft is greater than or equal to the acceleration threshold, the period count is incremented by 1;

[0065] If the period count is greater than or equal to the period threshold, automatically trigger the takeoff wake turbulence interval timing.
