The "CL650 Crew App" App provides you as a flight crew on the Challenger 650 with a very handy and intuitive remote control interface for your aircraft cabin system. It lets you control all aspects of the business jet cabin environment directly from your iPad Electronic Flight Bag via the onboard Wireless LAN. In addition it allows you to control briefing playback and override light settings in the cabin. The App turns your personal device into a fully-fledged wireless controller for the niceHD(R) system. *** ATTENTION *** The "CL650 Crew App" App is only useable on Bombardier Challenger 650 Business Jets that have Lufthansa Technik's niceHD(R) Cabin Management System installed. Without a correctly configured niceHD(R) system the "CL650 Crew App" will not provide any functions! For further information please contact Lufthansa Technik. *** ATTENTION ***
