Section 9
Supplements
Section 1 - General
This supplement lists the approved portable oxygen systems that may
be used in the aircraft 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
Above 18,000 ft a mask covering the nose and mouth of the user must
be used. Use of cannulas above 18,000 ft is prohibited.
The following portable oxygen systems and dispensing units are
approved for use in the aircraft:
Model Capacity
XCP-682 682 L
XCP-415 415 L
XCP-180 180 L
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.
