More new features have been added this week along with some other minor changes. Here are the highlights: New feature: Aircraft upgrades. This allows you to upgrade your older aircraft with for example a retrofit hushkit package that reduces the noise level of the aircraft (noise restrictions will be added soon as a new feature). All newly released aircraft upgrades are announced at the newsfeed at Dashboard and you can install them from My Aircraft pages. At the first step all upgrades are related only to noise reducing hushkits (aircraft models: BAC 1-11, B707, B727, B737-100/-200, Fokker 28, DC-8, DC-9, MD-80) but other types of upgrades may be added in the future. Staff management page (Personnel Office) has been updated and has now a new layout and some new functions. One essential change is that staff at different base airports are now displayed individually instead of being grouped into one. You can now manage salaries and staff numbers of each base airport one by one. There are also new quick management tools and also a change to manually balance staff between base airports (if under automatic staff settings this is done automatically). As always you can keep track of these changes and additions by reading our forums.
