“…The question remains whether there is an optimal flight direction. Some authors have proposed approaches to reduce the effective flying time (Girardet et al 2014), i.e. this is the time that the UAV takes from take-off, to landing, and to increase the energy-efficiency of the platform (Rodriguez et al 2016).…”

Soil erosion, rapid geomorphological change and vegetation degradation are major threats to the human and natural environment. Unmanned Aerial Systems (UAS) can be used as tools to provide detailed and accurate estimations of landscape change. The effect of flight strategy on the accuracy of UAS image data products, typically a digital surface model (DSM) and orthophoto, is unknown. Herein different flying altitudes (126-235 m) and area coverage orientations (N-S and SW-NE) are assessed in a semi-arid and medium-relief area where terraced and abandoned agricultural fields are heavily damaged by piping and gully erosion. The assessment was with respect to cell size, vertical and horizontal accuracy, absolute difference of DSM, and registration of recognizable landscape features. The results show increasing cell size (5-9 cm) with increasing altitude, and differences between elevation values (10-20 cm) for different flight directions. Vertical accuracy ranged 4-7 cm but showed no clear relationship with flight strategy, whilst horizontal error was stable (2-4 cm) for the different orthophotos. In all data sets, geomorphological features such as piping channels, rills and gullies and vegetation patches could be labeled by a technician. Finally, the datasets have been released in a public repository.

“…Another group of research methods studied the potential benefits of transitioning from the route structure to wind-optimal routes. Multiple studies, for instance [11][12][13], looked for the benefits from flying wind-optimal trajectories in the continental airspace. However, to our knowledge, very few publications discussed this problem for the oceanic airspace.…”

The North Atlantic oceanic airspace is considered the most congested oceanic airspace in the world. For many years, air traffic control in this airspace has experienced difficulties due to the limited radar coverage. To support conflictfree flight progress, a structure of routes, called Organized Track System, is established in the North Atlantic airspace and very restrictive separation standards are applied. The development of the Automated Dependent Surveillance-Broadcast system provides an opportunity to improve the flight planning operations over the oceans by reducing separation norms. The aim of this study is to improve the traffic efficiency in the North Atlantic airspace by developing new approaches to organize the transatlantic traffic at the strategic level. The first considered approach proposes a new route structure, referred to as Wind-Optimal Track Network, to replace the Organized Track System, while the second one is based on Wind-Optimal Free Routes. The problem is modeled as an optimization problem and resolved further via Simulated Annealing combined with Sliding Window algorithm. Results of simulations performed on the real traffic data prove that about 76% of flights decreased their cruising times by more than half an hour when flying wind-optimal tracks rather than using their great circle routes from the departure to the destination. Furthermore, by comparing the two proposed methods we conclude that Wind-Optimal Free Routes implies lower cruising times, while the Wind-Optimal Track Network is much more robust under changing wind fields.

Air traffic across the North Atlantic airspace has witnessed an incessant increase over the last decades. However, the efficiency of transAtlantic air traffic management is still low nowadays due to the limited radar coverage. The availability of Automated Dependent Surveillance-Broadcast systems represents an opportunity to enhance the strategic flight planning over the oceans by reducing the separation standards. Besides, oceanic flights are subject to very strong winds. Flying wind-optimal route yields to a significant fuel and time savings. In this paper, we propose a new transAtlantic route structure that benefits from the jetstreams in order to construct windoptimal flight trajectories. Then, we introduce an optimization model for detecting and resolving conflicts. The analysis is carried out on real traffic data to prove the efficiency of the developed method. Experimental findings show that our approach provides encouraging results in terms of conflict resolution and induced delays.
