  2. 1. Optimization of Aircraft Arrival Operations for Improved Environmental Efficiency

    Author : Henrik Hardell; Tatiana Polishchuk; Valentin Polishchuk; Ramon Dalmau-Codina; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The transportation sector, accounting for about one fifth of all greenhouse gas emissions, is facing a significant transformation in order to become more climate-friendly. In terms of air transportation, there are several important steps on the way to making flying sustainable both for the planet itself and for people directly or indirectly being exposed to its effects.

  4. 2. Impact of Weather on Air Traffic Control

    Author : Anastasia Lemetti; Valentin Polishchuk; Tatiana Polishchuk; Junzi Sun; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Weather has a strong impact on Air Traffic Management (ATM). Inefficient weather avoidance procedures and inaccurate prognosis lead to longer aircraft routes and, as a result, to fuel waste and increased negative environmental impact. READ MORE

  5. 3. Decision Models for the Procurement of Subsidised Air Services

    Author : Alan Kinene; Tobias Andersson Granberg; Valentin Polishchuk; Clas Rydergren; Svein Bråthen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Small communities or remote regions are usually ignored by airlines because they have insufficient passenger demand and the air services to and from these regions are unprofitable. Free market conditions would lead to the lack of air connectivity to and from remote regions, hence transportation authorities intervene by procuring air services to guarantee improved accessibility for these regions.

  6. 4. Models for the Procurement of Subsidized Air Services : Conventional Aircraft and the Adoption of Electric Aircraft

    Author : Alan Kinene; Tobias Andersson Granberg; Clas Rydergren; Valentin Polishchuk; Jesper Larsen; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : In liberalized air transportation markets, governments often adopt subsidy schemes through which they ensure air services along routes that are deemed commercially non-viable but economically and socially essential. The objective of these subsidized air service routes is to ensure a minimum level of services to outlying communities or remote regions that are difficult to access—by other modes of transportation—from the capital, other main cities or a hub airport yet can not be served commercially due to thin demand.

  7. 5. Development of critical enablers for Unmanned Traffic Management

    Author : Leonid Sedov; Valentin Polishchuk; Tobias Andersson Granberg; Yan Xu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : As the interest in drones continues to grow in both commercial and leisure markets, governments around the world are preparing to face the new challenges arising from unmanned operations. Safe and efficient handling of this novel drone traffic warrants an Unmanned Traf-fic Management (UTM) system capable of dealing with the envisioned high traffic densities. READ MORE
