Description / Abstract:

This ARP covers the basic criteria for the design of cabin pressure control systems (CPCS) for general aviation, commercial and military pressurized aircraft.

Purpose

Pressurization of the aircraft cabin is generally the most satisfactory method of achieving required partial pressures of oxygen for both crew and passengers during high-altitude flight. It provides a nearly normal environment in the cabin for the safety and comfort of the occupants by maintaining the internal cabin pressure higher than the flight altitude pressure. This permits normal physiological functions without the encumbrance of pressure suits or supplemental oxygen.

The purpose of this recommended practice is to provide the aerospace industry with guidelines encompassing the safety, comfort, automation and technical design considerations of aircraft cabin pressure control systems.

Goals are:

a. To ensure aircraft and occupant safety

b. To maintain crew and flight attendant performance

c. To ensure aircraft passenger comfort

Field of Application:

This recommended practice is applicable to pressurized aircraft, both civil and military, regardless of the number of passengers or crew. The Cabin Pressure Control System (CPCS) shall provide maximum safety to the passengers and crew throughout changes in cabin pressure altitude during the entire aircraft flight, as well as during ground operation. Additionally, the CPCS shall maximize passenger and crew comfort to the greatest extent possible, without exceeding aircraft structural safety limits.
