eeCrewConnect is a complex system for detection and notification of Schedule Changes towards the Crewmembers whose Schedules are updated. Additionally, the system also offers possibilities of sending AdHoc notifications as well as numerous other advanced features. With JETCRW, the eeCrewConnect system is complemented with the possibility to communicate with Crewmembers and provide them with detailed information on the fly via their mobile Devices. Besides increasing the amount and quality of data sent to the Crewmembers via this new channel, the feedback from Crewmembers will be instantaneous. I.e. for any message sent via the JETCRW channel to Crewmembers it is now possible to instantly know whether the Crewmember has actually seen the notification. This significantly improves the quality of communication between Crewmembers and Crew Support Services.
