An Analysis of Controlled Flight into Terrain (CFIT) Accidents of Commercial Operators 1988 through 1994

This investigation focused on the identification and analyses of factors that are potentially associated with fatal Controlled Flight Into Terrain (CFIT) accidents involving commercial operators. Central to the objectives was an attempt to highlight differences between CFIT accidents of air taxi, regional and major carriers. The research focused...

NASA-NLR long-line experiment; a first step to connected Air Traffic Management research facilitiest

A data-communication link via Internet has been established between the Crew-Vehicle Systems Research Facility (CVSRF) at the NASA Ames Research Center and the CTAS/NARSIM Simulation Facility (CNSF) at the NLR. Multiple simulated arrival flights of the Advanced Concepts Flight Simulator (ACFS) for Amsterdam Airport Schiphol in the Netherlands...

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....

PROCRU simulation results compared with Metro II in-flight ILS approach data

The PROCRU (Procedure Oriented Crew) model has been developed for the analysis and modeling of flight crew procedures during an ILS approach. The model's specific capability concerns the generation of "timelines" of the necessary actions to be carried out by each crew member during the approach. Besides, also the corresponding timelines for...

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...

Investigation on MLS approach path interception and transition techniques: part II: flight simulator investigation

Due to the wide coverage volume of MLS, in both azimuth and elevation, the system enables the introduction of new approach and terminal area procedures. For several years the NLR has been investigating the potential of MLS with respect to the execution of non-straight-in approaches. In an earlier theoretical study four MLS-guided interception...

A model and experimental analysis of pilot decision making behaviour for various approach conditions

This report deals with an investigation of pilots' failure detection performance in a realistic moving-base flight simulator. The task considered was the monitoring of stabilized automatic approaches. Abnormal conditions (excessive windshears or system failures) were to be detected on the basis of unacceptable deviations of displayed variables...

The effect of visual information on the manual approach and landing

The visual scene is an important source of information for the manual approach and landing task. This study deals with the effect of this information in combination with basic display information on the manual approach performance. In this context, a pre-experimental theoretical analysis has been performed in terms of the optimal control model....

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...

Wind shear on the approach: An investigation on the infuence of a tower measured wind environment on the symmetric motions of a simulated aircraft in an automatic approach

Measured wind profiles from the Royal Netherlands Meteorological Institute 200 m meteorological tower at Cabauw have been used to estimate wind shear effects on the symmetric motions of an approaching aircraft. Wind profiles as well as an automatically approaching DC-9 aircraft have been simulated on an electronic analog computer. The study...

Exploratory investigation of decelerating approaches of a twin-engined jet transport: Vol. II: Moving-base simulation and comparison with related experiments

Aircraft noise perceived on the ground can be reduced by decelerating the aircraft during the landing approach. As an additional benefit the lower thrust settings existing during a part of the approach and the shorter approach time result in a reduced fuel consumption as compared to a conventional approach. This report deals with an experiment...
