Q

If center hydraulic system fluid quantity is low, is it likely that the gear actuation system has lost all available pressure sources?

A. No, if center hydraulic system fluid quantity is low, the center system fluid is isolated to provide an alternate extension source.
B. Yes, if center hydraulic system fluid quantity is low, the alt. extension system has lost all available pressure sources.
