Despite the sharp drop in demand due to the COVID-19 crisis runway capacity will be a considerable bottleneck for the development of air transportation during the next decades. The construction of new runways in sufficient distance to existing ones would bring a relief but is often blocked by settlement structures in the direct vicinity of the airp...
With the ever increasing volume of air traffic comes an enormous environmental impact, specifically due to carbon emissions. A promising approach to reduce this impact is the introduction of en route air-to-air refueling, allowing for the design of aircraft with reduced weight and a decreased fuel burn. Aside from the design of aircraft, the key ch...
Sectorless air traffic management (or flight-centric
ATC as it is known in the SESAR context) is a novel
concept that restructures the airspace to make better use of the
human controller as a resource. Currently investigations on the
introduction of a team concept for sectorless air traffic
management is being conducted. As part of this team concep...

In order to balance demand and capacity in en-route ATM, the current practice is to partition the airspace into sectors. Each sector is assigned to a pair of air traffic controllers, a team of executive and planner. This controller team is responsible for the traffic within the sector. When the workload reaches the sector capacity limit, the sector...
The aim of the present paper is to demonstrate how a subset of methods from Cognitive Work Analysis (CWA) in combination with Social Network Analysis (SNA) can be used to analyse the effects of a reduced crew in a legacy system of a commercial airliner’s two-pilot-crew operations.

Single Pilot or Reduced Crew operations offer benefits cost savings, improvements in crew scheduling and in aircraft availability. However, safety concerns have so far prevented the introduction of single-pilot flights in commercial aviation. Introducing a remote Co-pilot station or even a remote-copilot center addresses these concerns. The present...
In this paper we proposes a density-based airspace management system for future U-Space. The concept focusses on the integration of new airspace users (e.g., UAS and Urban Air Taxis) into uncontrolled airspace (here airspace G). The advantage of the proposed concept is that it opens up the airspace equally for lowly equipped and highly-equipped UAS...
Noise, especially in the vicinity of airports, is one of the most important factors of modern air transport systems, especially at mayor hub airports. New approach designs like curved Required Navigation Performance (RNP) procedures to independent parallel runway systems can decrease the noise footprint in sensitive ground areas without reducing ai...
In air traffic management, optimization is often restricted to local areas, e.g., to the vicinity of airports. Procedures around these areas stay unchanged, and effects from optimizations concerning ecological efficiency are not considered adequately. Investigating new concepts, this typically results in local gain of efficiency without proving the...

Current initiatives for UAS airspace integration mostly aim at small or medium sized drones. However, it can be foreseen that there will be a demand of cargo UAS for payload in the range of 1000 kilograms. It proves to be a challenge to integrate those larger drones into a national airspace. The concept of choice for this problem is the minimum ris...
The importance of Unmanned Aircraft Systems (UAS) is growing in all aspects of aviation. Platforms range from small, user‐friendly off‐the‐shelf drones (“micro UAS”) to large transportation aircraft. One possible scenario for civil UAS or Remotely Piloted Aircraft System (RPAS) operation is freight transport, ranging from small and urgent deliverie...
Existing manned cockpit operations consider the reduction of the team of pilots to one pilot to save costs, improve crew scheduling and aircraft availability. However, safety concerns have so far prevented the introduction of single-pilot flights in commercial aviation. This study seeks to address these concerns by offering an alternative tripartit...
Sectorless air traffic management is an en-route concept, which eliminates the need for control sectors. Instead of assigning a geographic area (sector), air traffic controllers are assigned certain aircraft. Controllers are responsible for their assigned aircraft all the way from entry to exit. In previous simulations, one controller was responsib...

Modern flight management systems (FMS) are able to predict highly precise 4D trajectories for complete flights from take-off to touchdown. The generated trajectories take into account aircraft’s performance parameters, altitude-, speed- and time constraints, given procedures, and the expected weather conditions, as forecasted. Based on these trajec...
From the perspective of flight guidance, the development of laterally segmented or curved approach procedures that allow for rerouting around congested areas is a promising strategy for coping with noise issues. To help pave the way for independent operations of segmented approaches at airports with parallel runway systems, an elementary safety con...
The paper deals with a steeper approach profile to increase altitude of the aircraft during approach for noise mitigation. To allow a standard 3° landing and thus a higher rate of applicability the vertical approach profile is divided into 2 segments. It starts at about 8000ft AGL with a 4,5° slope. At about 1500 ft AGL the approach slope transitio...

According to Sheridan and Verplank's classification of levels of automation, taxiing on an airport still has a very low automation level. Key element for increased automation in taxi guidance is a precise and reliable navigation capability. As a Ground Based Augmentation System (GBAS) can fulfill the stringent requirements for a precision approach,...
In sectorless air traffic management the airspace is considered as one piece instead of partitioning it into sectors. The air traffic controllers are no longer in charge of sectors but are given responsibility for a certain number of aircraft during their entire flight. This entails that the controller has to keep track of several different traffic...
The idea of sectorless ATM (Air Traffic Management) envisages the airspace as a whole instead of dividing it into sectors. The dismissal of sectors, however, necessitates the definition of a
complete and unambiguous set of flight rules in order to regulate which aircraft has to introduce an avoidance maneuver in case of a conflict.
This paper desc...
The current practice to organize the airspace and to balance demand and capacity is the partitioning of airspace into sectors. With the increase in air traffic a common practice has been to decrease the size of the sectors in order to limit the workload of the ATCos. However, this approach has its limits. With the increasing number of sectors the n...
