Im philosophischen Diskurs der Gegenwart spielt das Thema der Gründe und der Begründungen eine zentrale Rolle. Vernünftiges Handeln zeichnet sich nach vielfach vertretener Auffassung dadurch aus, dass es dafür gute Gründe gibt, und vernünftiges Interagieren ist durch Prozesse des Gründe‐Gebens und Gründe‐Akzeptierens bestimmt. Im Beitrag soll betrachtet werden, welche Gründe eine politische und welche eine juristische Argumentation stützen und wie diese Formen des Begründens sich zueinander verhalten.
Business aviation is a relatively small but steadily growing and little investigated emission source. Regarding emissions, aircraft turbine engines rated at and below 26.7 kN thrust are certified only for visible smoke and are excluded from the nonvolatile particulate matter (nvPM) standard. Here, we report nvPM emission characteristics of a widely used small turbofan engine determined in a ground test of a Dassault Falcon 900EX business jet. These are the first reported nvPM emissions of a small in-production turbofan engine determined with a standardized measurement system used for emissions certification of large turbofan engines. The ground-level measurements together with a detailed engine performance model were used to predict emissions at cruising altitudes. The measured nvPM emission characteristics strongly depended on engine thrust. The geometric mean diameter increased from 17 nm at idle to 45 nm at take-off. The nvPM emission indices peaked at low thrust levels (7 and 40...
The life-cycle costs (LCC*) approach is used to gain transparency, to compare variants and to have a reliable basis for long-term-budgeting of investments, maintenance and operation with the goal of most favourable total costs of ownership (TCO*) for a given level of service for reliability, availability, maintainability, safety, health and environment, functionality, comfort (RAMSHEFC).
The cash flow cycle is essential to a business's survival. Often, the process is delayed between the stages of acquiring orders, creating work results, invoicing, and receiving payments from customers. Managing cash flow can therefore be a challenge, particularly in the start-up phase or when expanding.
All of the principal items of flight performance involve steady flight conditions and equilibrium of the airplane. The same is true for the performance of boards and boats when sailing and foiling. A comparison of most basic parameters between aircrafts and sailcrafts reveals similarities in the understanding of the principal physical laws as well as variations and differences in their application to create a balance of forces when dealing with weight, lift, drag and driving forces (propulsion).
