When does the demand valve operate in the diluter demand oxygen regulator?

  1. Always when the system is turned on

  2. When the user breathes

  3. At a preset altitude

  4. When the pilot adjusts it

The correct answer is: When the user breathes

The demand valve in a diluter demand oxygen regulator operates in response to the user's breaths. This ensures that oxygen is only released when the user inhales, conserving the supply and preventing over-oxygenation. Option A is incorrect because the demand valve does not continuously supply oxygen when the system is turned on, it responds to the user's breaths. Option C is incorrect because the demand valve does not operate based on altitude, but rather on the user's inhalation. Option D is incorrect because the pilot does not control the demand valve, it is controlled by the user's breaths.
