Airport traffic consists of aircraft performing landing, takeoff and taxi procedures. It is controlled by air traffic controller (ATC). To safely perform this task he/she uses traffic surveillance equipment and voice communication systems to issue control clearances. One of the most important indicators of this process efficiency is practical airport capacity, which refers to the number of airc...

The capacity of a runway system represents a bottleneck at many international airports. The current practice at airports is to land approaching aircraft on a first-come, first-served basis. An active rescheduling of aircraft landing times increases runway capacity or reduces delays. The problem of finding an optimal schedule for aircraft landings is referred to as the “aircraft landing problem”...

A STATISTICAL SEPARATION STANDARD AND RISK-THROUGHPUT MODELING OF THE AIRCRAFT LANDING PROCESS Babak Ghalebsaz Jeddi, Ph.D. George Mason University, 2008 Dissertation Director: Dr. John F. Shortle In the context of a high demand for runways as important scarce resources of the national air transportation system, this dissertation is concerned with the problem of determining the best separation ...

As the demand for the civil aviation has been growing for decades and the system becoming increasingly complex, the use of systems engineering and operations research tools have shown to be of further use in managing this system. In this study, we apply such tools in managing landing operations on runways (as the bottleneck and highly valuable resources of air transportation networks) to handle...

This paper analyzes the optimal level of operations on a single runway used only for arrivals. Two risks associated with landing procedures are the risk of a wake vortex encounter and the risk of simultaneous runway occupancy. We develop optimization models to maximize successful landing operations while mitigating these risk factors. The risks are mitigated by enforcing go-around procedures wh...

background: single leg drop landing is one of the common sport activities that have greater likelihood of leading to traumatic oflower extremity. however, there is limited understanding of biomechanics of this maneuver. hence, this study aimed to compare the activities of lower limb muscles during pre- and post phases of single leg drop landing. methods: this semi-experimental research of 13 ph...

The landing mechanisms of a basic dance jump, known as a sauté, have not been fully explored and the effect of shoe design on landing mechanisms is unknown. This study used 3D motion analysis to explore sagittal plane kinematic differences in a dance jump landing as a result of wearing jazz shoes. Jazz shoe design significantly affected metatarsophalangeal and midfoot motion, suggesting a reduc...

As the demand for air transportation continues to grow, some flights cannot land at their preferred landing times because the airport is near its runway capacity. Therefore, devising a method for tackling the Aircraft Landing Problem (ALP) in order to optimize the usage of existing runways at airports is the focus of this study. This study, a hybrid Genetic-Cuckoo Search (GCS) algorithm for opt...
