The game engine and interface have been updated again with several new features: Preliminary notice - Aircraft noise regulation rules. The new feature of aircraft noise limit rules will be activated in the near future in all game worlds. This means that airlines are not able to fly very old equipment (not having at least "Chapter 3" noise certification) for example in Europe or US during the modern era. Aircraft information and fleet listing pages. A new page combining aircraft information and production data (replacing the 'Global Statistics' page). Completely new features at this page are the "Largest operators" listing, the "Fleet listing" table and the "Area of production" data. Aircraft production line dynamics updated. The smaller aircraft models require now less orders to stay in production (among other minor changes). Added also clear information to aircraft pages about the status of the production line, and the possible ending date. Route oversupply warnings are reformatted for better usability. Please see details from the forums (link below).
