The development team over at TFDI have announced a new project in the works at FSExpo called PACX. PACX introduces a whole new way of flight simming for those wanting a little extra when they hop into the sim. In the real world every situation is dynamic in a commercial airliner, your responsibility as the captain is to get those passengers and crew safely to their destination in an as efficient of a manner as possible. The goal of PACX is to bring those scenarios to life in the sim giving virtual pilots a whole knew way to experience flying. This includes new dynamic crew announcements which are shown off in the Youtube video below.
As part of PACX you can now interact directly with crew and passengers to notify them of any possible delays, which can boost customer satisfaction. Whereas failure to notify them can lead to decreased satisfaction. Notifying passengers of potential problems in the air can keep them more calm during emergency situations.
TFDI has said that this add-on will work with any aircraft while direct cockpit integration will only be done with select aircraft. This add-on will also be made to work with X-Plane so everyone can enjoy the fun PACX can offer.
All of this information and more can be found here on the TFDI Forum.
