Synopsis
EMB-145 flight crew reported loss of hydraulic pressure and safely continued to destination.
Narrative
During cruise flight we got an indication on the EICAS of HYD 1 LO QTY quickly followed by HYD SYS 1 FAIL; AIL SYS 1 INOP; and E1 HYD PUMP FAIL. While running the QRH for the HYD SYS 1 FAIL the hydraulic quantity in system 1 went from amber to full quantity green without any direct interaction and HYD 1 LO QTY message disappeared while all other messages remained. The pressure in system 1 rapidly decreased to 0 psi. I turned on the electric hydraulic pump; but the hydraulic page still showed the pump was off and the pressure remained at 0 psi with the hydraulic quantity still showing full green.With the inability to recover hydraulic system 1 we reviewed the loss of systems attached to it and decided to Request Priority Handling with ATC because of the loss of steering capability on landing. I sent an ACARS to dispatch that we had Requested Priority Handling; ran the QRH; were planning on runway XXR; and would need a tug upon landing. I then called the flight attendant and told him that we had lost a hydraulic system; had 20 minutes until landing; that we would be stopping on the runway to then get attached to a tug to taxi to the gate; the landing would be precautionary with no evacuation or bracing. After that I made a PA to the passengers saying pretty much the same thing. Once the QRH was completed we were vectored onto the visual approach for XXR. After landing we came to a complete stop on the runway; were inspected by CFR (Crash Fire Rescue) for leaking fluids; attached to a tug and pulled into our gate.
Second reporter narrative
Hydraulic system 1 fail in cruise - Advised ATC; landed without incidentDeparted ZZZ without incident; while in cruise we received a HYD1 LOW QTY; then less than a second later HYD SYS 1 FAIL. CA ran QRH. Since the system 1 fluid quantity was in the green range; CA turned on the electric pump; but the electric pump did not turn on; which was unusual. System did not recover; so we Requested Priority Handling because steering would be inoperative on landing. I gave controls to Captain while I actuated the gear on downwind; then took controls back. ATC did a great job prioritizing us; approach and landing were normal; I used only engine 2 thrust reverser and braked as normal. We stopped on the runway; ARFF (Airport Rescue and Fire Fighting) met us on the runway; and ops towed us into the gate. Really great work from everyone involved; make the process go smoothly.
