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...

Pilot performance in automated cockpits: a comparison of moving and nonmoving thrust levers

Two different design-philosophies with respect to the Man-Machine Interface of current auto thrust systems were compared in a flight simulator study. With the so-called moving thrust lever concept, the positions of the thrust levers are servo-controlled by the auto thrust system. Hence, the thrust levers provide the pilot with additional...

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 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...

Low-speed handling qualities of advanced transport aircraft; A comparison of ground-based and in-flight simulator experiments

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....

Determination of low-speed longitudinal manoeuvring criteria for transport aircraft with advanced flight control systems

The application of Active Control Technology concepts and in particular the Relaxed Static Stability principle in certain categories of future transport aircraft will lead to the introduction of primary flight control systems incorporating full-time stability augmentation. For this category of transport aircraft adequate handling quality...

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...

Performance and workload analysis of in-flight helicopter missions

The study described in this report was aimed at assessing the potentials of the optimal control model structure to predict the important characteristics of realistic operational helicopter missions. The theoretical and experimental results indicate that the optimal control model succesfully predicts the best attainable (rather than the average)...

Human pilot describing function, remnant and associated information for pitch attitude control: in flight and ground-based tracking experiments

Servo-analysis techniques, using mathematical models of human control behaviour, are effectively used in studies of the system formed by the human pilot and the flight control system/aircraft combination. Measurement and data analysis techniques for the determination of pilot describing function, remnant and associated information needed in...
