Aircraft Equipment Problem Less Severe
Flight Crew Landed in Emergency Condition; General Declared Emergency
Aircraft
After leveling in cruise Hydraulic System 1 Overheat was presented on the EICAS. We ran the QRH and we were supposed to cycle the system once every 15 minutes for 1 minute until we landed with the system on. We declared an emergency. The second time we tried to pressurize and cycle the system it would not pressurize. We then ran the Hydraulic system 1 Failure Checklist and confirmed with Maintenance Control that we had a Hydraulic System 1 failure. We made the decision with Dispatch and Maintenance to continue the flight to destination. We went as far as to run a practice Gear Extension Checklist in cruise since neither of us had done this procedure making sure we both understood how it would occur when preparing to land. Nothing could be done to prevent the mechanical failure but I feel the techniques and skills we have developed though training helped ensure a positive outcome.
EMB145 First Officer experiences a hydraulic system 1 overheat after leveling at cruise altitude. QRH procedures require the pump to be turned off and cycled on for one minute every 15 minutes. On the second cycle the system will not pressurize and QRH procedures for a failed hydraulic system 1 are complied with. Flight continues to destination.
