5.6 Normal Operations
5.6.1 Oxygen System Preflight
Prior to engine start, pull the oxygen control knob to activate the oxygen system and
verify system pressure on the BOTTLE PRESSURE gauge.
The PASSENGER MASK selector should be in the AUTO position to allow for
automatic mask deployment.
Verify oxygen flow to quick don mask (s) by viewing the flow indicator in the oxygen
line. Set the regulator to the 100% and test mask operation by removing the mask
and depressing the red lever on the side of the regulator to inflate the harness. Also
breathe from the mask to assure oxygen flow.
5.6.2 Oxygen Duration
Federal aviation regulations require that one pilot wear an oxygen mask and use
oxygen above FL350.
Operations under 14 CFR Part 91 require a 10 minute supply of oxygen for all
passengers in the event of a cabin depressurization. The 22 cubic foot bottle
meets this requirement.
Operations under 14 CFR Part 135 require a two hour supply of oxygen for each
crew-member and a 10 minute supply for all passengers. The 40 cubic foot
bottle meets these requirements.
