meaning - What does "as" mean in this context?

Properly trained safety diver(s) shall be available as determined by the manager.

Sometimes "as" means "when". For example, "as necessary" means "when it is necessary". Then, for the example above, does it "as determined" mean "when it is determined by the manager"? or does it mean "whenever it is needed based on the manager's decision"?

Answer

In that context it has the meaning of "like" for example "All employees should attend the meeting on Friday as previously stated by the manager"

As previously stated means "like previously stated"

As and like sometimes have the same meaning.
