Description

Pressurisation is used to create a safe environment on board of airplanes flying at high altitudes (generally above 13,000 feet). Compressed air is pumped into the cabin trough an environmental control system.

This application measures the differential pressure and relative altitude of a pressurised aircraft cabin.

There are 5 cockpit design available:

• PIPER CHEYENNE: preferred for turboprop aircrafts (max 5.5 ΔP)
• CESSNA CITATIONJET: based on the notorious biz jet (max 8.9 ΔP)
• CESSNA CITATION X: based on the fastest biz jet (max 9.6 ΔP)
• BOEING 737: preferred for jet airliners (max 9.1 ΔP)
• AIRBUS A320: preferred for jet airliners (max 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 provide 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 provide 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. The Mach indicator is based on estimated indicated airspeed and altitude.

LIMITATION:
• A strong GPS signal is necessary. Place your iPhone 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.
