Which setting on the PRESS MAN switch selects manual pressurization mode?

The manual pressurization mode for the Dassault Falcon 7X is selected by setting the PRESS MAN switch to ON. In this mode, the pressurization system allows the flight crew to directly control the cabin altitude, providing the ability to make adjustments based on specific operational conditions or preferences without relying on the automated systems. This is particularly useful during certain phases of flight, such as takeoff and landing, where manual control may be desired to ensure optimal cabin pressure settings.

The other settings do not enable manual control; for instance, the AUTO setting allows the aircraft’s automated systems to manage cabin pressure automatically, while the OFF setting would deactivate the pressurization system entirely. The ST-BY option typically puts the system in a standby mode where it’s ready to be activated but does not directly facilitate manual pressurization control. Thus, the ON setting is essential for pilots requiring direct management of cabin pressure during flight operations.
