Can you provide a link or reference to this CASA REQUIREMENT?
I would LOVE to...
You will find it specifically listed under Civil Aviation Order 20.11, Appendix IV. One example I will pull from there on page 14 of the CAO Appendix IV, 1.4d;
"(d) use of first aid kits."
And just to add because you don't think it's a CASA REQUIREMENT;
"1.3 Oxygen. Methods of use of fixed and portable oxygen equipment."
And another section of the appendix;
"2.2 Oxygen. Applicable to operations on pressurised aircraft and where the provision of
oxygen is required.
(a) A knowledge of the effects of altitude on:
(i) respiration; and
(ii) hypoxia; and
(iii) duration of consciousness at various altitudes without supplemental oxygen;
and
(iv) gas expansion; and
(v) gas bubble formation.
(b) A knowledge of:
(i) the physical phenomena of decompression; and
(ii) precautions in use of oxygen; and
(iii) location of oxygen equipment carried."
Glad that I can point out one of the many requirements placed on cabin crew based in Australia.
