Towards 4D Trajectory Tracking for Transport Aircraft

Queueing Models for 4D Trajectory-Based Aircraft Operations in NextGen

This paper develops a queueing model for aircraft landings at a single runway under trajectory-based flight operations. The situation is expected to arise in the Next Generation Air Transportation System. Aircraft are assigned scheduled times of arrival, which they meet with some stochastic error. It is assumed that errors are small enough for scheduled order to be maintained, and they follow a...

4D Trajectory Generation and Tracking for Waypoint-Based Aerial Navigation

One of the operational requirements for unmanned aerial vehicles is the autonomous navigation and control along a given sequence of waypoints, or along a predefined trajectory. Existing autonomous navigation procedures are mostly done in 3D because of the stringent certification requirements for 4D flight and due to the complexity in coping with time of arrival at waypoints, whilst actual fligh...

Robust Trajectory Tracking for a Small-scale Hybrid Aircraft

By hybrid aircraft, we mean a UAV that can vertically take-off, land and hover like a helicopter, and meanwhile can be converted to a fixed wing airplane to achieve high forward speed and long endurance than normal helicopters. This paper presents our recent work on control of a novel small scale hybrid aircraft. The proposed aircraft should follow a specific trend of trajectory to be able to c...

A soft dynamic programming approach for on-line aircraft 4D-trajectory optimization

Trajectory Management for Aircraft Noise Mitigation

This paper gives an overview of aircraft trajectory management aimed at producing noise abatement procedures. Area Navigation (RNAV) concepts play an important role in the design of flexible and, therefore, noise friendly depart or approach procedures. In addition, the lowest dispersion of RNAV tracks help to contain noise footprints in a smaller area if compared with footprints that are produc...
