guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

Runway length is usually a critical point in an airport system so, a great interest has been created for optimal use of this runway length. The most important factors in modeling of aircraft landing problem are time and cost while, the costs imposed on the system because of moving away from target times have different performances in terms of impact. In this paper, firstly, aircraft landing pro...

This paper deals with the study and comparison of passive and active landing gear system of  the aircraft and dynamic responses due to runway irregularities while the aircraft is taxying. The dynamic load and vibration caused by the unevenness of runway will result in airframe fatigue, discomfort of passengers and the reduction of the pilot’s ability to control the aircraft. One of the objectiv...

This paper aims to study the multiple runway case of the static Aircraft Landing Problem (ALP), where all data are known in advance. In the first part of this work, we propose a formulation of the problem as a mathematical programming model in order to reduce the number of constraints (which can positively reduce the computing time) and to give a more rigorous formulation. In the second part, w...

London Heathrow airport is one of the busiest airports in the world as it is very popular with both airlines and passengers. The capacity of the departure system at Heathrow is limited by the capacity of the runway. It is therefore imperative to maximise the throughput of the single available departure runway. Aircraft taxi from the stands to the ends of the runway where they queue in holding p...

The characteristics of a dynamic implementation of the single-runway aircraft landing problem were analysed using some well-known datasets. Given the nature and degree of complexity of this problem, a specific hybrid algorithm was developed, consisting of a stochastic and a deterministic element. The deterministic scheduler divides the aircraft into logical landing sequences as part of the recu...

This paper addresses the problem of scheduling aircraft landings at an airport. Given a set of planes and runways, the objective is to minimize the total (weighted) deviation from the target landing time for each plane. There are costs associated with landing either earlier or later than a target landing time for each plane. Each plane has to land on one of the runways within its predetermined ...
