“…These intervals ensure a reduced risk of collision in case the lead aircraft blunders or in case of a wake vortices clash. The same boundaries were used by Amir H. F. et al [3] to develop previous Genetic Algorithms making them more efficient while still respecting all of the constraints. Then Robert.…”

“…The research carried out by Amir H. F. et al had as its basis a HITL simulation where automation was responsible for finding and suggesting pairs, while controllers took care of evaluating and deciding whether to accept or reject the suggested pairs [3]. Solving a problem involving 100 aircraft took less than 40 seconds on average, which is considered an acceptable response time.…”

“…The HITL simulations showed that a pairing algorithm with a turnaround time of less than half a minute was sufficient. In most cases, where the number of aircraft was 35 or fewer, the pairing result was available in less than 10 seconds [3]. The algorithm, despite its quick runtime, generated high-quality pairing results.…”

“…The algorithm, despite its quick runtime, generated high-quality pairing results. Evaluation of the Human In The Loop (HITL) simulation data revealed that more than 97% of the pairs proposed by the algorithm were deemed acceptable by the air traffic controllers involved [3]. It is important to note that the HITL adopted an improved genetic algorithm (GA) [3] that was initially developed by Michael K [2].…”

Close parallel runway operations play a critical role in maximizing airport capacity and facilitating efficient aircraft arrivals and departures. However, the close proximity of parallel runways presents unique challenges during landing operations, including the risk of runway incursions, wake turbulence, and communication issues. This research paper aims to conduct a comprehensive survey of existing studies on close parallel runway landing operations, analyzing the various approaches employed by airports worldwide. The objective is to identify the most effective method for managing very closely recommendations. The survey encompasses factors such as runway spacing, air traffic control procedures, knowledge, and the identification of best practices. This study aims to contribute to the enhancement of safety and operational efficiency in close parallel runway environments. The findings of this survey will be valuable for airport operators, air traffic control agencies, and aviation authorities in making informed decisions.

The effect of crosswinds on paired approach (PA) procedures for Closely Spaced Parallel Runways (CSPR) is investigated in this paper by fully utilizing the crosswind environment to implement a more efficient PA and increase runway capacity. An improved wake dissipation model is used to quickly predict the change in the wake velocity field for the PA procedures. The change in the width of the hazard zone is explored in detail using the roll moment coefficient as a determination index. The calculation method for the hazard zone of a wake encounter in a PA is designed considering the influence of crosswind, turbulence, and ground effect. The results show the diffusion rate of the hazard zone and a decrease in the width of the maximum hazard zone under a breezeless environment with increases in the turbulence intensity. The maximum hazard zone width decreases with an increase in crosswind speed. Favorable crosswinds can reduce wake separation and improve the efficiency of a PA. Lower turbulence intensity has a better crosswind effect under a normal PA. The 3-degree offset PA can accommodate larger unfavorable crosswinds, with a higher turbulence intensity having a better crosswind effect. The 3-degree offset PA can substantially increase the proportion of time when no wake affects the PA procedure.
