The Perspective Touch avionics work to provide the CPCS controller with the information it needs to make adjustments within the cabin. Such information includes landing field elevation (LFE), barometric measurements and aircraft altitude all taken from the programmed flight plan. The controller senses changes to cabin pressure and uses an auto schedule (plan of control) to provide regulated air pressure to the valve control chambers. The controller is able to develop an ascent schedule for takeoff, climb, and cruise – as well as a descent schedule.
When ascending to cruise altitude, the controller gradually decreases cabin pressure until it equals the cabin operational ceiling altitude of less than 8,000 feet. Pressure is decreased by exhausting air through two separate valves out of the cabin and into the baggage compartment, also providing a small amount of supplemental heat. When descending, the controller gradually increases cabin pressure so that cabin altitude matches the destination field elevation.
The Vision Jet pressurisation system also includes a Cabin Pressure Dump button, which can be engaged in case of an emergency to instantly and rapidly depressurise the cabin. This button is clearly labeled on the overhead panel with a transparent guard.
All of this works together to take additional pressure off the pilot workload and ensure a comfortable, reliable, and responsive experience in your Vision Jet. Rest easy, and enjoy the ride.
