ATPL: Consider the flight deck oxygen supply system. The purpose of the oxygen regulator (as a function of demand and altitude) is to 1. decrease oxygen pressure from 1800 PSI (in the bottles) down to about 50-75 PSI (low pressure system) 2. supply pure oxygen 3. supply diluted oxygen 4. supply oxygen at normal pressure 5. supply oxygen at emergency/positive pressure6. trigger the continuous cabin altitude warning at 10000 ft cabin altitud The combination regrouping all the correct statements is:
