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”...

This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in...

In this paper we describe two approaches for solving the problem of scheduling aircraft landing times. In this problem, the air traac controller must compute a landing time for each aircraft in the horizon, and must attempt to minimise costs whilst observing a number of hard constraints. The costs are associated with aircraft landing times varying from the preferred landing time. The hard const...

Integrated Vehicle Health Management (IVHM) is one of the few technologies that will help in reducing both maintenance and operational costs, while improving the overall safety of an aircraft. It also helps in moving away from conservative design philosophies. Hence IVHM is increasingly being adopted in various aircraft programs. IVHM requires a multi-disciplinary approach bringing together the...

In this paper, a novel approach to UAV’s automatic landing on the ship’s deck is proposed. We present the design of the cooperative object, and then begin our basic research on UAV autonomous landing on a ship by using computer vision and affine moment invariants. We analyze the infrared radiation images in our experiments by extracting the target from the background and then recognizing it. Al...

This paper examines some of the challenges that must be overcome if future aerial delivery systems are to have the capability to land on the flight deck of a ship underway. The unique aspects of trajectory planning for landing on a ship’s flight deck are first examined, followed by formulation of the position estimation problem for a moving target. Some preliminary investigations into character...

Simulation and the resulting prediction of the dynamic behavior of an aircraft and its landing gear system during ground maneuvers is an essential part in the design process. A realistic estimation of unwanted oscillations, such as gear walk and shimmy, for the landing gear and whole aircraft can be readily obtained with an MBS-model. It is then possible to adjust the model for changes in the s...

The paper presents the automatic control of aircraft in longitudinal plane, during landing, by using the linearized dynamics of aircraft, taking into consideration the sensor errors and other external disturbances. Aircraft auto-landing is achieved by combining two control techniques: H2 and H∞ approaches; this way, a robust H2/H∞ controller is obtained. Within the robust H2/H∞ controller, the ...

Preliminary note Numerical simulation procedures for landing dynamics of large transport aircraft are briefly presented. Developed numerical procedures allow for determination of dynamic response of landing aircraft for different flight and touch-down parameters. A non-linear dynamic model of landing aircraft, which serves as a basis for computational procedures, is synthesised by modelling of ...

Aircraft carrier deck operations present a complex and uncertain environment in which time-critical scheduling and planning must be done, and to date all course of action planning is done solely by human operators who rely on experience and training to safely negotiate off-nominal situations. A computer decision support system could provide the operator with both a vital resource in emergency s...
