Welcome to another edition of the CSS Blog where we keep you up to date with our latest developments.
This update includes a huge number of fixes and a number of new features.
Firstly, we've added a large number of custom sim events so you can assign things like MCP buttons, lights and radios to your devices. This also allows support for automatic frequency tuning and switching with both the default ATC and addons.
Second, we've added the ability to import flight plans from SimBrief to FMC using the CO-RTE function.
Third, we've added a virtual crew (the first officer can adjust the brightness of their displays and announce airspeeds on takeoff, while the cabin crew adjust the cabin lighting, arm and disarm doors and make cabin announcements and cabin reports to the cockpit).
We've described how it all works in detail in the manual, and we really hope you'll read it.
Crew Sound Packs are fully customizable and can be airline-specific. We've created a special channel in our official Discord for sharing these packs.
A significant portion of the update will also affect the cockpit: a TO card has been added, along with an animated checklist, sunshades, the ability to hide the EFB, and many other small details that make the cockpit even more realistic.
