Backup Systems Helped Control Doomed Jetliner

01.20.09 | FL News Team

The National Transportation Safety Board says backup systems installed on a powerless U.S. Airways jet helped the pilot control the giant machine last week. When the The US Air jet flown by Captain Chesley Sullenberger met a flock of geese on Thursday, both engines were destroyed and that power was lost.

Now the NTSB is saying an auxiliary power unit in the rear of the jet was still running and provided backup power while a small propeller driven turbine pump maintained hydraulic pressure for controls. Data provided by recorders aboard that jet may be used in the future in simulators so other pilots can understand what Captain Sullenberger did to maintain a controlled descent into the Hudson River.
