26.46 Portable protective breathing equipment
       (1) When a pressurised aircraft begins a flight with at least 2 pilots, as required by or under the civil aviation legislation or the AFM, it must be carrying portable protective breathing equipment (portable PBE units) for each flight crew member in accordance with this section.
       (2) Each portable PBE unit must:

(b) the part protecting the wearer's eyes:
 (i) must not adversely affect vision in any noticeable way; and
           (ii) must allow corrective glasses to be worn in a normal position; and
(b) be able to supply oxygen, or a mixture of oxygen and another suitable gas, continuously for at least 15 minutes.
       (3) Portable PBE units must be located as follows:
(a) for a flight where no crew members other than the minimum flight crew members are carried — 1 portable PBE unit must be located in, or as close as practicable to, the flight crew compartment;
(b) as far as practicable — 1 portable PBE unit must be located adjacent to each of the hand-held fire extinguishers required to be carried on a flight under Division 26.13;
