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 ...

This paper introduces the forced landing problem for UAVs and presents the machine-vision based approach taken for this research. The forced landing problem, is a new field of research for UAVs and this paper will show the preliminary analysis to date. The results are based on video data collected from a series of flight trials in a Cessna 172. The aim of this research is to locate " safe " lan...

This article describes a novel approach to the real-time visualization of 3D imagery obtained from a 3D millimeter wave scanning radar. The MMW radar system employs a spinning antenna to generate a fan-shaped scanning pattern of the entire scene. The beams formed this way provide all weather 3D distance measurements (range/azimuth display) of objects as they appear on the ground. Using these im...

The progressive integration of automation technologies in commercial transport aircraft flight decks -the “glass cockpit” -has had a major, and generally positive, impact on flight crew operations. Flight deck automation has provided significant benefits, such as economic efficiency, increased precision and safety, and enhanced functionality within the crew interface. These enhancements, howeve...

Effects of speed stability and turbulence upon airspeed response of an aircraft flying under landing approach conditions are investigated by considering response to turbulence when the aircraft is constrained to fly along a straight flight path by means of the elevator. The speed-stable and speed-unstable cases are treated in a uniform manner by considering the way in which airspeed 'diffuses' ...

This paper presents the use of different artificial life-based optimization algorithms and cerebellar model articulation controllers (CMACs) in aircraft automatic landing control. The proposed intelligent control system can act as an experienced pilot and guide the aircraft landed safely in wind disturbance condition. Lyapunov theory is applied to obtain adaptive learning rule and stability ana...

This document describes operations associated with a set of flight experiments and demonstrations using a Boeing757-200 (B-757) research aircraft as part of low visibility landing and surface operations (LVLASO) research activities. To support this experiment, the B-757 performed flight and taxi operations at the HartsfieldAtlanta International Airport (ATL) in Atlanta, GA. The B-757 was equipp...

This paper describes the Human Error Identification (HEI) Technique called the Human Error Template (HET). HET has been developed specifically for the aerospace industry in response to Certification Specification (CS) 25.1302. In particular, it is intended as an aid for the early identification of design-induced errors, and as a formal method to demonstrate the inclusion of human factors issues...

The problem of the feedback control of an aircraft landing in the presence of windshear is considered. The landing process is investigated up to the time when the runway threshold is reached. It is assumed that the bounds on the wind velocity deviations from some nominal values are known, while information about the windshear location and wind velocity distribution in the windshear zone is abse...
