Description

Method, device and system for triggering takeoff wake interval timing based on track situation

technical field

The invention relates to the technical field of civil aviation management, in particular to a method, device and system for triggering take-off wake interval timing based on track situation.

Background technique

The tower control automation system (hereinafter referred to as the tower system), with the Advanced Surface Movement Guidance System (A-SMGCS) and the Electronic Progress Sheet System (EFS) as the core, has the functions of monitoring data processing, alarm processing, path planning, lighting guidance, and flight data processing and record and playback functions. The tower system is a control and command system suitable for the air traffic control tower department. It integrates multiple sets of air traffic control automation, advanced surface movement guidance, tower electronic progress list, digital air traffic control, coordinated release, weather, and lighting control required by tower control. The function of the system can simultaneously provide the air and surface situation display and various flight and surface conflict warnings for the tower controller.

The tower electronic process order system is an important system for the air traffic control tower department to implement ground command. It provides tower controllers with an integrated system for the management of incoming and outgoing aircraft on the ground and various control instructions by processing flight plans and dynamic telegrams. .

In order to prevent dangerous approaches or collisions of aircraft in the air, the International Civil Aviation Organization has made detailed regulations on various intervals in flight, including en route flight, airport terminal area flight, arrival and departure flight and other stages. Wake separation is one of the very important flight separations. When two aircraft take off continuously, in order to ensure the safety of the aircraft (to prevent the wingtip vortex generated at the wingtip of the front wing from affecting the flight of the rear aircraft), according to the regulations, the interval must be 1-3 minutes, mainly depending on the front and rear. Depends on the wake conditions of the aircraft type. Because the interval is too long, it will also affect the efficiency of runway operation. Especially in airports with a large number of flights, it will lead to delays of departure flights and affect the regular rate of flight departures. Therefore, how to accurately and safely grasp the interval between departure aircraft is particularly important.

At present, in the tower control automation system or the tower electronic process order system, the minimum safe wake interval time parameter for two consecutive aircraft takeoffs is pre-defined. When the state of the electronic progress sheet manually operated by the tower controller is TKF (takeoff) or ROL (rolling) state, the system interface starts timing display, and the displayed wake timing time varies according to the difference between the front and rear models. When the timing reaches the minimum safe wake interval time for two consecutive aircraft to take off, the timing stops or the interface has a color reminder. At this time, the controller can issue take-off instructions to the next aircraft that is about to take off. The ultimate goal is to ensure that two consecutive aircraft take off. Aircraft taking off maintain sufficient safe wake separation.

Above-mentioned traditional technology has following shortcoming:

Relying on the manual operation of the tower controller to trigger the start time of the take-off wake interval timing is inaccurate, usually there is a time difference of 20 seconds to 40 seconds. Referring to the take-off wake interval standard, the maximum interval is 180 between the front giant aircraft and the rear aircraft light aircraft. Seconds, the minimum interval is 80 seconds for the same model before and after, so the error rate is calculated to be between 11% and 50%. At the same time, the end time of the corresponding timing is not accurate, which eventually leads to inaccurate grasp of the minimum safe wake interval time of the two continuous take-off aircraft. The time is too long, which reduces the efficiency of runway use; the time is too short, which affects the flight safety of the aircraft.

The reasons for the above disadvantages are:

The starting moment of the take-off wake interval timing is triggered entirely by the tower controller manually operating the electronic progress sheet when the state is TKF (takeoff) or ROL (rolling) state, and the tower controller needs to visually observe the runway in most cases , the status of the operation process order will not be timely, so there will be situations of early operation or delayed operation.
