A novel take-off and landing system using ground based power is proposed in the EUFP7 project GABRIEL. The proposed system has the potential benefit to reduce aircraft weight, emissions and noise. A preliminary investigation of the feasibility of the structural design of the connection mechanism between aircraft and ground system has been...

Every year, despite today's advanced electronic guidance systems, a handful of aircraft still plough into mountains in most cases killing all occupants. Such accidents are usually caused by a combination of low visibility and difficult terrain conditions. In mountainous terrain the modern precision guidance system known as the Instrument Landing...

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...

From recorded Distance Measurement Equipment (DME) data during Microwave Landing System (MLS) flight trials performed at London Gatwick Airport (April 21 - 26, 1989) using the NLR Fairchild Metro II Laboratory Aircraft, the position of the aircraft was determined by post-processing and compared with the MLS- and ILS-derived positions. This...

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...

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...

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...

MLS provides the possibility to define non-straight-in approach paths and to use more advanced interception procedures. From an ATC point-of-view it became necessary to structure this capability as a prerequisite in order to make a realistic use of the potential capabilities of MLS. Four different MLS approach path interception procedures were...

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...

An analysis is given of possible interference induced by a position marker system, called RASP, into aircraft radio altimeters. The RASP system is used as a marker beacon in flight tests for trajectory measurements, and operates on 4.3 GHz. It is concluded that radio altimeters will not experience any harmful interference from a RASP transmitter.

In this report a model of the human observer and decision maker is described. A submodel of the human observer is formulated in linear estimation theoretical terms including the perception of the displayed information of a linear process and the central information processing stage. The subsequent decision process is described in terms of...

The STALINS method for measuring take-off and landing trajectories is briefly described and results of flight tests made in 1978-80 are discussed. The method now meets the requirements to which it was designed, and a few improvements in the hardware and software are being finalized. The method is expected to be ready for operational use in the...

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....

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...

Smit, J. (author)
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...

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...

A description is given of flight tests related to the effect of various levels of (artificial) positive stick force stability on the longitudinal controllability in the landing approach of an attitudestabilized aircraft. Approach performance and pilot commentary of 60 ILS/VASIS approaches flown with a twin-engined jet transport have been...
