FAA certification for Liebherr-Aerospace cabin pressure controller

The United States Federal Aviation Administration has certified the digital pressurization system, developed and integrated by Liebherr-Aerospace, for the Hawker Beechcraft aircraft programs Hawker 750 and Hawker 900XP. The digital pressurization system allows the flight crew to take off, climb, cruise and descend while having the ideal cabin pressure automatically scheduled. This automated system relieves passenger fatigue associated with abrupt pressure changes and reduces pilot workload in flight. Pressurization can still be controlled manually at any time if desired.
