van Dijk, Tom (author)
With a growing number of drones, the risk of collision with other air traffic or fixed obstacles increases. New safety measures are required to keep the operation of Unmanned Aerial Vehicles (UAVs) safe. One of these measures is the use of a Collision Avoidance System (CAS), a system that helps the drone autonomously detect and avoid obstacles....

The aim of this report is to document the output of the three workshops and the questionnaire. The results of the Flood risk analysis has been reported in another Floodsite report: De Bruijn et al., 2008. For a complete description of the Schelde pilot study reference is made to Chapter 8 of the FLOODsite book on pilot sites (Schanze, in prep.).

The paper draws lessons from our empirical investigations in Germany, Italy and England/Wales in a very specific perspective: It formulates recommendations for flood risk management with people at risk. Thus it tries to shed light on the views of this important – but often neglected – group of stakeholders. Our addressees are flood risk...

Risk awareness and personal preparedness are seen to be important parameters in an integrated risk management scheme today. This study is contributing to the knowledge base about the perception of risk. Regarding the risk of storm-surges, an assessment of the perception and the status of personal preparedness of the people are addressed in an...

The report discusses the findings of a questionnaire survey carried out in five localities of the Mulde catchment (Germany) in 2005 (N=404). All these settlements were heavily affected by the 2002 August flood. Both an event- and a phase-sensitive approach are applied from a bottom-up perspective of the people affected. This specific...

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...

This report describes the concept of reliability of nondestructive inspection (NDI) and reviews the different aspects involved. First, the probability of detection (POD) of flaws in flawed specimens is discussed. To provide a measure of confidence in an estimated POD, lower botind values of this probability at a given confidence level are...

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....

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...

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...
