Section 9 Cirrus Design
Supplements SR20
Section 1 - General
This supplement lists the approved portable oxygen systems that may
be used in the SR20 when supplemental oxygen is required by the
applicable operating rules, as well as provides mounting instructions
and general operating procedures for all approved systems.
Section 2 - Limitations
Smoking is not permitted in the SR20.
The following portable oxygen systems and dispensing units are
approved for use in the Cirrus Design SR20:
The system must be configured so that at least one mask capable of
covering the nose and mouth is available for use.
If nasal cannulas are provided in addition to the mask(s), the
instruction sheet provided by the cannula manufacturer must be
affixed to the tubing on each cannula and available to each user. The
instructions must contain the following information:
• A warning against smoking while oxygen is in use;
• An illustration showing the correct method of donning; and
• A visible warning against use of the cannula with nasal
obstructions or head colds with resultant nasal congestion.
The oxygen bottle must be secured in the right front seat so that the
pilot can view the oxygen pressure gage and operate the regulator.
When the oxygen bottle is installed, the seat may not be occupied in
flight and the maximum occupancy is reduced by one.
Oxygen storage bottles were hydrostatically tested at manufacture and
the date stamped on the bottle. The storage bottle must be hydrostatic
tested and recertified every 5 years.
