Abstract:Current air traffic management in the terminal area is based on published sets of standard routes. However, a new procedure called the continuous descent approach has been recently proposed to decrease noise disturbances. To allow increased use of continuous descents and simultaneously increase performance in terms of other important aspects such as throughput, it may be beneficial to replace the predetermined fixed approach trajectories with more flexible trajectories instead. This is studied through optimizi… Show more
“…It provides researchers with a powerful tool that can be adapted to various uses [16]: for example research into human (motion) perception [17], [18], [19], aircraft handling qualities [20], [21], fly-by-wire control algorithms and flight deck displays [22], [23], flight procedures [24], [25] and air traffic control [26]. The simulator's flexible software architecture and high-fidelity cueing environment allows the integration of the B747 model from Smaili et al [9].…”
This paper considers sliding mode allocation schemes for fault tolerant control. The schemes allow redistribution of the control signals to the remaining functioning actuators when a fault or failure occurs. The paper analyzes the schemes and determines conditions under which closed-loop stability is retained for a certain class of faults and failures. It is shown that faults and even certain total actuator failures can be handled directly without reconfiguring the controller. The results obtained from implementing the controllers on the SIMONA research flight simulator, configured to represent a B747 aircraft, show good performance in both nominal and failure scenarios even in wind and gust conditions.

Energy management and energy state awareness are important concepts in aircraft safety analysis. Many loss-of-control accidents can be attributed to poor energy management. Energy-based metrics provide a measurable quantity of the energy state of the aircraft and can be viewed as an objective currency to evaluate various safety-critical conditions. In this work, we have surveyed key energy-based metrics from various domains and identified the challenges of implementing these metrics for General Aviation operations. Modifications to existing metrics and definition of some new energy metrics are proposed. A methodology is developed that can be used to evaluate and visualize the energy metrics. These energy metrics can then be used to understand and enhance General Aviation aircraft safety using retrospective flight data analysis.
“…The difference in speed will at some point result in an unnecessary large gap, which is basically a waste of capacity. A situation where each aircraft would be flying its own customized and optimized trajectory can eliminate both disadvantages (Vormer et al, 2006). It allows for optimizing for individual performance, and it can prevent aircraft with different speed behaviour to fly the same trajectory.…”
