However, the current practice in the field is mostly human centered. The Japan Aerospace Exploration Agency has been developing a decision support system for aircraft operation in order to promptly plan and execute rescue missions. The current research focuses on evacuation missions in particular and investigates the potential of particle swarm optimization with an integrated greedy search in aircraft resource management. A robust particle model is proposed that can reflect various helicopter properties as well as evacuation mission characteristics. Particle swarm optimization parameters are modified and set based on numerical simulations, and the values determined in this way are used in an optimization of disaster relief mission assignments based on real data obtained during the Great East Japan earthquake and tsunami of 2011. The swarm is initialized with a greedy-search ...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Although there are methods for identifying the Pareto front of a design space, these methods can be computationally prohibitive, and it is still left to the designer to choose which design on the front to build. Consequently, multiobjective optimization often involves specifying a scalar utility function and then optimizing with respect to this utility function. Preference elicitation algorithms can aid the designer in constructing this utility function. In preference elicitation for engineering design optimization, the ideal algorithm would converge to an accurate utility function with as few preference queries to the designer as possible. This paper extends a prior method for preference realization and tailors it for use in engineering design optimization by deriving a less restrictive inference technique and applying an entropy-based method for posing queries that converges faster to the true global utility function than existing algo...","PeriodicalId":179117,"journal":{"name":"J.

However, existing methods for such efforts are limited. They rely on predefined criteria to identify risks, leaving emergent issues undetected. This paper presents a new method, cluster-based anomaly detection to detect abnormal flights, which can support domain experts in detecting anomalies and associated risks from routine airline operations. The new method, enabled by data from the flight data recorder, applies clustering techniques to detect abnormal flights of unique data patterns. Compared with existing methods, the new method no longer requires predefined criteria or domain knowledge. Tests were conducted using two sets of operational data consisting of 365 B777 flights and 25,519 A320 flights. The performance of cluster-based anomaly detection to detect abnormal flights was compared with those of multiple kernel anomaly detection, which is another data-driven anomaly ...","PeriodicalId":179117,"journal":{"name":"J.

Nominally, this system serves as a passive monitor but, in high-risk situations, warnings and (ultimately) override actions are initiated to mitigate the high-risk situation. In this work, flight safety assessment and management is applied to the task of preserving safety during takeoff, which is one of the highest-risk phases of flight. Flight safety assessment and management is specified as a deterministic Moore machine that can ultimately be certified using existing software certification processes. To facilitate understanding and to reduce state-space complexity, flight safety assessment and management’s state machines are split into longitudinal and lateral-directional submachines that identify and mitigate loss-of-control contributing factors associated with aircraft dynamics and control ...","PeriodicalId":179117,"journal":{"name":"J.

One drawback of the current traffic alert and collision-avoidance system design is limited support for closely spaced parallel runway operations. The traffic alert and collision-avoidance system alerts, too frequently, leading pilots to often inhibit resolution advisories during approach. Research is underway on the Airborne Collision Avoidance System X, which is a next-generation collision-avoidance system that will support new surveillance systems and air traffic control procedures. The Airborne Collision Avoidance System X has been shown to outperform the traffic alert and collision-avoidance system for en route encounter scenarios. However, the design parameters that are tuned for the en route environment are not appropriate for closely spaced parallel landing operations. One concept to allow for closely spaced parallel landing operations is a procedure-specific mode of the logic...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Due to the power capacity limitations in airborne devices such as the flight management system, a fast method should be implemented to calculate the full trajectory cost. Many flight management systems use a set of lookup tables with experimental data for each flight phase, and they are called performance databases. In this paper, the trajectory flight cost is calculated using a performance database instead of using classical equations of motion. The trajectory to be calculated is composed of climb, acceleration, cruise, descent, and deceleration. The influence of the crossover altitude during climb and descent, as well as step climbs in cruise, was considered. Lagrange linear interpolations were performed within the performance database discrete values to calculate the required values. By providing a takeoff weight, the initial and final coordinates, and the desired flight plan, the trajectory ...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Strategic air traffic management aims to resolve the imbalance for offnominal conditions (for example, convective weather events) through redistributing flows and resources at the strategic timeframe (2–15 h in advance). As a component of scenario-driven strategic air traffic management, this paper develops a multiresolution spatiotemporal distance measure that, combined with standard distance-based clustering algorithms, can be used to group a wide range of possible weather-impact scenarios into a few representative clusters to facilitate corresponding management strategy design. Motivations of this new distance measure, its generation algorithm, and parameter impact analysis are described in detail to facilitate practical implementation and subsequent use in decision support.

An in-cruise optimization method has been implemented to calculate the optimal trajectory that reduces the flight cost. A three-dimensional grid has been created, coupling lateral navigation and vertical navigation profiles. With a dynamic analysis of the wind, the aircraft can perform a horizontal deviation or change altitudes via step climbs to reduce fuel consumption. As the number of waypoints and possible step climbs is increased, the number of flight trajectories increases exponentially; thus, a genetic algorithm has been implemented to reduce the total number of calculated trajectories compared to an exhaustive search. The aircraft’s model has been obtained from a performance database, which is currently used in the commercial flight management system studied in this paper. A 5% average flight cost reduction has been obtained.","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

It is essential that those obstacles be displayed to the pilots in a way that enables them to fly as safely as possible. Two different symbology concepts were suggested for display of obstacles: spatial and guidance displays. The spatial symbology shows the pilot where the obstacles are, whereas the guidance symbology recommends the preferable route and flight altitude. A personal-computer-based simulation study was conducted to compare four helmet-mounted display symbologies of obstacles. Three of the symbologies tested were of the spatial concept (one plan view and two conformal forward views), and the fourth was of the guidance concept. Twenty-one pilots completed a simulated task, similar to a search-and-rescue mission, under a degraded visibility environment condition while maintaining the exposure time as short as possible within two experiments.
