    Creating a framework for community integration of urban air mobility.
    (Cranfield University, 2022-03) Organ, Aaron John; Mason, Keith; Rothe, Henrik
    Technological advancements in propulsion systems, alternative fuel, battery power and storage, and autonomy have led to the development of a new generation of aircraft. These enabling technologies inclusive of Small Unmanned Aircraft Systems (sUAS), Large Cargo Unmanned Aircraft (LUCA), and electric Vertical Take-off and Landing (eVTOL) or electric Conventional Take-off and Landing (eCTOL) aircraft fall under the umbrella term of Advanced Air Mobility (AAM). The current literature, in addition to regulators and the industry, is heavily focused on the aircraft and technology integration. This research contributes to a literature gap concerning ground infrastructure and community integration of AAM. The research aims to provide a framework of next steps relevant to state and city planners and policy makers. Subject matter experts from key AAM stakeholder groups were consulted through the execution of semi-structured interviews to produce a rich dataset of the issues and challenges of integrating AAM into the state and city’s transportation systems. The systematic approach of thematic analysis was used to identify top themes and sub-themes. The results identified AAM success keys, potential use cases, anticipated benefits of AAM, anticipated obstacles to AAM adoption, and stakeholder roles at the city, state, and federal level. These results have provided a framework for cities and states of what to do in the initial phases to integrate Advanced Air Mobility technologies into their existing transportations networks for a more sustainable and robust system.

    Enabling real-time collaborative decision-making between airport and surface transport operations
    (Elsevier, 2023-12-13) Jimenez, Edgar; Blasco-Puyuelo, Juan; Alcolea, Ruben; Salamanca, Raquel; Rothe, Henrik; Moxon, Rich
    Current developments in collaborative decision-making in the air transport context are restricted to airport and air traffic management operations and stakeholders, disregarding the relevance of airport access and egress in the door-to-door journey for passengers. This paper summarises the IMHOTEP (Integrated Multimodal Airport Operations for Efficient Passenger Flow Management) concept of operations, which extends Airport Collaborative Decision-Making implementations by incorporating surface access. Enhanced situational awareness achieved by extending the monitoring of passenger flows beyond the airport boundaries improve resource allocation and last-minute capacity utilization. It also facilitates the identification of passenger connectivity requirements in terms of links to ground services.

    Integrated multimodal airport operations for efficient passenger flow management: Two case studies
    (Amsterdam University of Applied Sciences, 2022-12-06) Rothe, Henrik; Jimenez Perez, Edgar; Moxon, Rich; Ellis, Darren; et al.,
    Predictive models and decision support tools allow information sharing, common situational awareness and real-time collaborative decision-making between airports and ground transport stakeholders. To support this general goal, IMHOTEP has developed a set of models able to anticipate the evolution of an airport’s passenger flows within the day of operations. This is to assess the operational impact of different management measures on the airport processes and the ground transport system. Two models covering the passenger flows inside the terminal and of passengers accessing and egressing the airport have been integrated to provide a holistic view of the passenger journey from door-to-gate and vice versa. This paper describes IMHOTEP’s application at two case study airports, Palma de Mallorca (PMI) and London City (LCY), at Proof of Concept (PoC-level) assessing impact and service improvements for passengers, airport operators and other key stakeholders. For the first time one measurable process is created to open up opportunities for better communication across all associated stakeholders. Ultimately the successful implementation will lead to a reduction of the carbon footprint of the passenger journey by better use of existing facilities and surface transport services, and the delay or omission of additional airport facility capacities.

    The role of Austrian Airlines within the Lufthansa Group
    (Elsevier, 2023-12-28) Mayer, Robert; Ellis, Darren; Rothe, Henrik; Tschannen, Tim
    Austrian Airlines is a relatively small but important part of the Lufthansa Group, and is to some extent overshadowed by its much larger German owner, together with its higher profile Swiss International Airlines compatriot and neighbour. Even so, Austrian is not as small as the group's other network carrier member Brussels Airlines. The group's low-cost point-to-point carrier Eurowings is not closely considered in this paper as the primary focus here is on a network carrier analysis, with Austrian positioned as the main case study subject. In this regard, Austrian delivers a hub-and-spoke network out of Vienna International Airport (VIE) which both compliments and strengthens the overall group's scale, scope and density. Austrian contributes a substantial boost to the Lufthansa Group in Central and Eastern Europe, though this has been reduced as a result of the ongoing war in Ukraine, including Russian air space closure. Austrian's future prospects are closely aligned with events in Ukraine, with an end to the war likely to see the airline well positioned to resume services quite quickly to Ukraine, Belarus and Russia. The study here finds that Austrian Airlines clearly maintains a symbiotic relationship with its parent company, rather than a dependency on the wider group for its survival, though it would likely be a smaller airline if it was not part of the Lufthansa Group. They compliment each other.

    The impacts of shock events on airport management and operations: a systematic literature review
    (Elsevier, 2024-09-01) Gu, Yue; Wiedemann, Mirjam; Freestone, Robert; Rothe, Henrik; Stevens, Nicholas
    Unpredictable shock events have disruptive and long-lasting impacts on the aviation industry. However, the scale and type of impact of different shock events on airport operations and planning have been unevenly surveyed. A better understanding can help airports to improve their risk mitigation and develop more resilient operations and management. Through a systematic literature review of peer-reviewed research, we summarise shock events into four categories based on the cause of the shock: economic recessions, infectious disease pandemics, terrorist attacks, and natural disasters. The major impacts are identified as a reduction in air travel demand, interruptions in operations, modified operating procedures, and changes in facilities and infrastructure. We further bring these together into a conceptual typology of event-impact interactions. This longitudinal overview may assist airport managers in better understanding the impacts of shock events and taking further steps in developing more resilient airport infrastructure and associated business models.
