Description / Abstract:

Determine the required minimum oxygen concentration to be breathed prior to, during, and after a loss of cabin pressurization, and

Determine recommended means necessary to provide the required oxygen concentrations.


To prevent impairment of consciousness caused by hypoxia after decompression oxygen must be used as follows:

A. Above 24,000 and up to 40,000 feet the system must provide, in accordance with Figure 1:

(1) An increased minimum oxygen concentration prior to a decompression,

(2) A schedule of increased oxygen concentration with increase in cabin altitude,

(3) 100% oxygen at an altitude not higher than 24,000 feet, and

(4) Safety pressure to begin simultaneously with delivery of 100% oxygen.

B. Between 40,000 and 45,000 feet the system must provide, in addition to the above,

(1) Delivery of 100% oxygen under positive pressure, increasing with altitude to maintain no less than the equivalent of 40,000 feet.

C. When cabin altitude can not exceed 25,000 feet

(1) No change in present requirements.
