A stochastic control approach to flight path monitoring

In the Programme for Harmonised Air Traffic management Research in Eurocontrol (PHARE) Medium Term Scenario, a number of Advanced Tools are described which must be developed in order to increase Air Traffic Control capacity and the flight efficiency of aircraft while keeping at least the same level of safety. One of these Tools is the Flight...

Flight simulator evaluation of advanced MLS procedures

The flight simulator study described in this report concerns an evaluation of manually flown, flight director aided, curved MLS approach and departure procedures with a simulated wide-body transport aircraft. Four curved approach paths and two departure procedures have been evaluated, where these procedures were determined to be beneficial from...

Flight simulator evaluation of the flyability of curved MLS approaches with wide-body aircraft

The flight simulator study described In this report concerns an evaluation of flight director flown curved MLS approach paths with a simulated wide-body transport aircraft. Four curved approach paths, consisting of two straight segments and one 90 degrees circular segment with different straight final segment lengths, have been investigated....

Results of MLS procedural interception flight trials performed at Manchester Airport

In July, 1988, flight trials have been performed on the newly installed MLS equipment at Manchester Airport (UK), using one of the laboratory aircraft of NLR, a Fairchild Metro II with programmable avionics systems including a basic MLS receiver as an "Avionics Research Testbed". The aim of the tests was to prove that aircraft with basic IFR...

Flight simulator investigation on the approach path parameters for MLS curved approaches

The present flight simulator study has been addressed to the evaluation of the approach path parameters for curved approach paths. A number of seven oblique approach paths has been investigated, varying in both straight final length and oblique angle. The investigation was carried out for various operating minima (decision height, runway visual...

Comparison of a jump-diffusion tracker with a Kalman tracker: an evaluation with emphasis on air traffic control

A sophisticated starting point for a probabilistic approach to the radar tracking problem is a Markov jump-diffusion model for the aircraft dynamics, its control and the radar measurements. From nonlinear filtering theory, a closed form description of the evolution of the conditional distribution of this Markov process can be obtained. This jump...

Thresholds for the visual perception of position deviations and motion

During a visual approach to landing a pilot uses cues in the visual scene for the control of aircraft attitude and flight path. The accuracy with which some relevant display elements can "be set at a desired, nominal, position was determined in an experiment via the phychophysical "method of adjustment". Furthermore relevant literature with...

Visual scene perception process involved in the manual approach

The outside scene is often an important soiirce of information for manual control tasks. In the context of aircraft control the most important example is the visual approach scene. This study deals with modelling the visual scene perception process on the basis of linear perspective geometry and the relative motion cues and investigates its...
