according to their maximum take-off mass (MTOM) or pilot licenses based to the line of sight between the pilot and the drone (visual line of site—VLOS, beyond visual line of sight—BVLOS), special licenses allowing night flights, licenses for dropping materials, and others (Reger et al.,...
“legs”) are offered to passengers as one journey from their origin airport to the destination airport through a hub airport. With HSR, however, both these two legs need not be air flights: on legs where HSR service is comparable with flights in terms of (total) journey time and cost, ...
we solve the problem of the maximum cruise range for those three models; that is to say, we determine the evolution of the state variables: velocity and mass, the control variable: power setting, and the best range, also detailing the characteristics of the optimal flights and comparing them...
As for Jet A-1 production, the temporal scope is from 2015 to 2021 [43]. The different layout options allow us to analyze the production system that operates at typical energy conversion efficiencies achievable today, as well as at likely best-case efficiencies reachable in plant designs that ...

nonmotorized transportation is especially appropriate; medium distances should be covered by public transport if possible. Meanwhile long journeys, including intercontinental flights, may be limited to fossil fuel propelled aircraft. In the short term, the aim is to significantly lower CO2emissions for ...
3 For applications, this study employs the confidence level of τ=99% to VaR and τ=97.5% to CVaR, as proposed by the Basel II framework and the Basel Committee on Banking Supervision (2013). In addition, to generate the dynamic (or the time-varying) tail risk series, this study ...
This phenomenon is commonly referred to as “flight-to-safety”, which includes episodes that might be related, not only to “flights-to-quality”, but also to “flights-to-liquidity” (see Baele et al., 2019, García and Gimeno, 2014 or Beber et al., 2009). Changes in both the ...
This is similar to how GPS and IMUs work together, where IMUs provide high accuracy over short distances, while GPS provides periodic independent location information to prevent drift. Preventing drift is particularly important for long duration flights over large distances, typically made at high ...
In real-time flights, in addition to the aircraft's own performance, it is also necessary to consider flight conflicts, airspace limitation, real-time meteorological conditions, etc. Future work can be carried out by analyzing the factors that influence real-time flight performance as well as ...
