Honeywell Launches Next-Gen Digital Cabin Pressure Control, Monitoring System for Aircraft Honeywell has introduced the next generation of its Cabin Pressure Control and Monitoring System with applications in both commercial and military aircraft. This new version of the system is all-electric, lighter-weight, and available now for business and regional aviation as well as tactical or military trainer-sized aircraft. The Cabin Pressure Control and Monitoring System (CPCMS) helps maintain and monitor the air pressure inside an aircraft. It can be found onboard any aircraft that flies high enough to require air pressurization, including commercial and business jets as well as military aircraft. It regulates the air that is pumped into the cabin of an aircraft to maintain a safe and comfortable environment while flying at high altitudes. It also manages the rate of pressure change to avoid passenger discomfort during climb and descent.
