This paper presents four optimization algorithms: Bacterial Foraging Optimization (BFO), Particle Swarm Optimization (PSO), Chaos Particle Swarm Optimization (CPSO) and Bacterial Swarm Optimization (BSO), and a neural network compensator: Resource Allocation Network (RAN) to aircraft automatic landing control design. When wind disturbance is beyond the originally scheduled flight condition, the...

Landing gear is a structure that is mounted under the fuselage and helps the aircraft in takeoffs and landings. The most important duty of landing gear is the control of vibration exerted on the system through the shock absorber which is a common component to all the landing gear. Considering the importance of this issue, the necessity of investigating shock absorber with features such as high ...

Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...

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...

We study the problem of computing trajectories of a set of aircraft in their final descent, right before landing. Trajectories must be compatible with aircraft dynamics while keeping distance between aircraft large enough. Our objective is to determine the order in which aircraft land as well as their exact trajectories in order to minimize the maximal landing time. We study a highly simplified...

An emerging Next Generation Air Transportation System concept Equivalent Visual Operations (EVO) can be achieved using an electronic means to provide sufficient visibility of the external world and other required flight references on flight deck displays that enable the safety, operational tempos, and visual flight rules (VFR)-like procedures for all weather conditions. Synthetic and enhanced f...

Optimal scheduling of airport runway operations can play an important role in improving the safety and efficiency of the National Airspace System (NAS). Methods that compute the optimal landing sequence and landing times of aircraft, while delivering high quality solutions, must accommodate practical issues that affect the implementation of the schedule. One such practical consideration, known ...

An adaptive backstepping controller is designed for the automatic landing of a fixed-wing aircraft. The backstepping control scheme is adopted by using the nonlinear six degree-of-freedom dynamics of the aircraft during the landing phase. The adaptive law is integrated along with the backstepping controller in order to estimate the aircraft modeling errors as well as the external disturbance. T...

Situational awareness and decision-making are necessary to identify and select the optimal set of mutually non-exclusive hypothesis in order to maximize mission success by adapting system behavior accordingly. This paper presents a hierarchical and decentralized approach for integrated damage assessment and trajectory re-planning in aircraft with uncertainties in navigational decision-making. A...

Aircraft Landing Problem is to assign an airport’s runways to the arrival aircraft as well as to schedule the landing time of these aircraft. In this paper, due to the complexity of the problem, which is NP-hard, we develop an iterative-based heuristic by exploiting special characteristics of the problem. Computational results show the developed approach is quite competitive, and obtain optimal...
