A cost-effective avionics architecture to achieve high availability in small satellites

Aviate, Navigate: Functional Visualizations of Asymmetric Flight Envelope Limits

Current aircraft flight deck interfaces do not provide information on how a performance-altering failure constrains the aircraft's flight envelope. As a result, it is difficult for flight crews to plan an emergency landing trajectory. This study presents the results of the conceptual development of novel constraint-based interface symbology that...

Aircraft Separation Assurance Using Implicit Maneuver Coordination: Issues and Potential Solutions

In earlier research projects, the depiction of airspace in which a loss of separation is predicted to occur has been explored as a means to increase conflict awareness. The computation of the conflict space is based on the current state of traffic and ownship. If the traffic maneuvers, the location and extent of the conflict space will change...

Design and evaluation of a simulation environment for evaluating departure scheduling algorithms

To meet traffic demand predictions, the global air traffic management (ATM) system needs to be changed. Several visions on future ATM operations exist. A commonality between the different visions is 4D Trajectory management. This function enables plan-based operation as opposed to the state-based approach of the present system. Plan-based...

Deterministic Task Transfer in Network-on-Chip Based Multi-Core Processors

In this thesis we consider the application of multi-cores in safety critical real-time systems, especially avionics. In our literature study we extract two major challenges. Firstly the unpredictability that comes from the concurrent access of shared resources (especially the on-chip interconnect) must be dealt with. To address this we propose...

Research, design, simulation and implementation of an automatic flight control system for a real-time flight simulator

Vertigo Flight Simulation is a company located in The Netherlands with its mission being to design, produce and sell low cost flight simulation devices to all levels of the flight training market. One of the products which is developed by Vertigo Flight Simulation is the Vertigo P-2 Trainer. The P-2 Trainer is a fixed-base flight simulator...

Capacity Enhancement by Application of Multi-user Receivers and Power Control in a Cellular Radio System

At present, the GPS position sensor requirements are lower than the requirements that have to be met when using perspective flightpath displays. Besides the GPS position sensor requirements, data latency, data update rate, and display update rate, could cause the display presentation system not to meet all the requirements. As a result,...

Integrated design of a man-machine interface for 4-D navigation

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...

Het gebruik van glasvezels in de vliegtuiginstrumentatie

Fiber optics, a rapidly advancing new technology, seems very well suited for use as data transmission medium in aircraft. The advantages are substantial: galvanic isolation, electromagnetic compatibility, savings in volume and weight, and superior transmission qualities. In this report possibilities and limitations are discussed for using...

Reliability aspects of software for digital avionics

Modern commercial transport aircraft contain digital avionics systems for more and more safety critical functions. The reliability and safety of those new systems depend on the hardware reliability and on the reliability of the embedded software. In this report, an overview is given of available methods and techniques to develop reliable...

Trends in airline avionics

Modern avionics are an integral part of the aircraft. They provide the functions of communication, navigation, energy management, identification, weather, terrain, and collision avoidance, the presentation of flight and warning data as well as aircraft guidance and stabilization. New developments in micro-electronics and display technology...
