Narrative:
Descending out of 18;000 feet we lost the quantity and pressure on the green hydraulic system. We accomplished the appropriate checklists and set up for the approach. During the approach; the flaps would not extend with the use of the other two hydraulic systems. After we manually lowered the gear; the hydraulic fluid in the green system indicated a return to the normal level. At that point; we conferred with maintenance control and elected to use the green system electric pumps to lower the flaps which was not called for in the checklist. The flaps extended to the full position and we continued the approach and landing without incident.
