The atmospheric disturbances affect not only flying qualities of an airplane but also flight safety. According to flight records, most aircraft accidents occurred during final approach or landing. If the flight conditions are beyond the preset envelope, the automatic landing system (ALS) is disabled and the pilot takes over. An inexperienced pilot may not be able to guide the aircraft to a safe...

Landing an aircraft in a remote landing zone autonomously presents several challenges. Firstly, the exact location, orientation, and elevation of the landing zone is not always known; secondly, the accuracy of the aircrafts navigation solution is not always sufficient for this type of precision maneuver. This paper explores a method for estimating the relative position and attitude of the aircr...

This paper provides an overview of literature on visual perception for position and motion awareness in general, and focuses on the visual inputs used by human pilots for landing aircraft in particular. General introductions are given on the background of manual aircraft landing and on depth and motion perception. These fields are then brought together in a discussion of visual cues available d...

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...

A fuzzy reasoning-based method for scheduling air traffic in the terminal area has been designed at the NASA Ames Research Center and operationally tested at the Dallas/Fort Worth Terminal Radar Approach Control (TRACON). The scheduling system sequences and assigns landing times to arrival aircraft by utilizing continuous updates of aircraft radar data and controller inputs. The scheduling algo...

The effect of managing aircraft movements on the airport's ground is an important tool that can alleviate the delays of flights, specially in peak hours or congested situations. Although some strategic design decisions regarding aeronautical and safety aspects have a main impact on the airport's topology, there exists a number of other additional factors that must be evaluated according to the ...

In this paper, we explore the challenging and important problem of automated aircraft landing. We created a simulator to be able to perform online experiments in various conditions including stormy weather and starting from off-trajectory starting points. We experiment with a wide range of techniques to learn the optimal flight policy including reinforcement learning, Monte Carlo based dynamic ...

This paper addresses the problem of navigation system design for autonomous aircraft landing. New nonlinear filter structures are introduced to estimate the position of an aircraft with respect to a possibly moving landing site, such as a Naval vessel, based on measurements provided by airborne vision and inertial sensors.. By exploring the geometry of the navigation problem, the navigation fil...

In this paper, we consider priced-timed automata based exploration for resource-optimal scheduling. Resource-optimal scheduling problems can be seen as an application of real-time model checking in priced domains. State spaces for large problems can easily go beyond the main memory capacity. In this paper, we propose the use of secondary storage devices such as harddisk to store the generated s...

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 ...
