Pressurization 與 3Z RF Aligner 使用情況與統計

Pressurization is used to create a safe environment on board of airplanes flying at high altitudes (generally above 13,000 feet). To achieve this, compressed air is systematically introduced into the cabin through an environmental control system. This application monitors both the differential pressure and relative altitude within a pressurized aircraft cabin. The system provides users with a selection of five cockpit designs tailored to specific aircraft types: • PIPER CHEYENNE: Ideal for turboprop aircraft (maximum 5.5 ΔP) • CESSNA CITATIONJET: Modeled after the renowned business jet (maximum 8.9 ΔP) • CESSNA CITATION X: Crafted for the fastest business jet (maximum 9.6 ΔP) • BOEING 737: Designed for jet airliners (maximum 9.1 ΔP) • AIRBUS A320: Designed for jet airliners (maximum 8.6 ΔP) The cabin altitude gauge (CABIN ALT), displays the relative altitude inside the cabin of the aircraft in thousand feet. The differential pressure gauge (DIFF PRESS or ΔP) displays the difference between the air pressure inside and outside the aircraft in PSI. The higher the differential pressure, the lower the cabin altitude is at a same flying altitude. Example: a plane flying at an altitude of 25,000 feet with a cabin differential pressure of 5 PSI will have a cabin altitude of 9,100 feet while a plane flying at the same altitude but with a cabin differential pressure of 6 PSI will have a more comfortable cabin altitude of 6,700 feet. The variometer gauge (CABIN CLIMB) indicates how quickly the cabin is climbing or descending in feet per minute. The ground speed is displayed in Knots. LIMITATION: • A strong GPS signal is necessary. Place your iPad in a position where you get a clear view of the sky, preferably close to a window. It can take up to few minutes minutes to receive a good signal. • The Mach indicator relies on estimated ground speed and temperature, rather than true airspeed and temperature, rendering it incapable of providing precise readings.
