Solution space diagram in conflict detection scenarios

This research investigates the use of Solution Space Diagram (SSD) as a measure of sector complexity and also as a predictor of performance and workload, focusing on the scenarios regarding Air Traffic Controller (ATCO)’s ability to detect future conflicts. A human-in-the-loop experiment with varying intercept angle within the same sector layout...

Design of an Ecological Flow-based Interface for 4D Trajectory Management in Air Traffic Control

The concept of trajectory-based operations as proposed by SESAR and NextGen seeks to increase airspace efficiency and capacity by introducing time as an explicit control variable. Such form of operations lean heavily on the introduction of higher levels of automation to support the human air traffic controller in performing this new task. In...

An Ecological Approach to the Supervisory Control of UAV Swarms

This research employs ecological interface design to improve the human machine interface of an existing ground control station for the supervisory control of UAV swarms. As a case study, a general ground surveillance mission with four UAVs is envisioned. An analysis of the swarming work domain is performed to generate a reduced set of means-end...

Measuring Sector Complexity: Solution Space-Based Method

Time-based Spacing for 4D Approaches using Speed-Profiles

Two of the major projects in ATM development, SESAR and NextGen, both fore- cast the use of 4D trajectories as an intermediate phase in the development of full Performance Based Trajectories. Using 4D trajectories, the full positional and time coordinates of the aircraft are known throughout the planned trajectory. During approach, when reduced...

Continuous Descent Approaches with Variable Flight-Path Angles under Time Constraints

In order to reduce noise nuisance around Schiphol Airport, a Continuous Descent Approach procedure was introduced in the late ’90s. Unfortunately, because unpredictable individual aircraft behavior lead to increased landing intervals for this procedure, it is currently only applied during night time operations. Time-of-Arrival control in the...

The Effect of Synthetic Vision Enhancements on Landing Flare Performance

The usage of heads-down, non-conformal synthetic vision displays for landings below minimums has inherent problems during the flare due to minification effects. Literature showed that pilots can use four visual cues to perform a manual flare maneuver. Amongst their strategies, the Jacobson flare method seemed the most suitable to provide flare...

Towards Integrating Traffic and Terrain Constraints into a Vertical Situation Display

Future airspace operations will allow flight crews to plan and fly their own preferred route and time of arrival without much intervention from air traffic control. This implies that pilots become more responsible for planning their own route while maintaining safe separation. This requires a strategic planning tool that support a high level of...

Investigation of Energy Management during Approach: Evaluating the Total Energy-Based Perspective Flight-Path Display

This paper covers an analysis of the energy management task during the approach phase as well as the design of an experiment supporting this analysis. The energy management task is analyzed using the concept of energy rate demand, which expresses the amount of total energy to be lost in comparison to the minimal energy rate the aircraft can...
