The flight deck gaseous system can be turned on on demand. Which statement is true?

• A. It can be turned on on demand.
• B. It requires a maintenance request to operate.
• C. It is always on, with no control.
• D. It can only be turned on by the captain.

Answer: (A)

Activation by the flight crew on demand is how this system is designed to operate. The gaseous system in the flight deck is meant to be initiated when needed, giving pilots immediate control to respond to a situation. It is not something that requires a maintenance request to function, nor is it always on with no control. Activation isn’t limited to the captain in all procedures; it is typically accessible to the crew in the cockpit as part of standard operating procedures. So, the statement that it can be turned on on demand is the correct one.
