EMB-145 flight crew reported receiving a HYD1 LO QTY indication during cruise followed by a HYD SYS 1 FAIL message. The crew ran all pertinent checklists and decided to continue to their destination.
At cruise (approx. XA00) Captain and I noticed HYD 1LO QTY EICAS message appear. We pulled up the HYD system pages to monitor and saw that the indicator was in the amber. We then pulled the QRH for HYD 1 LO QTY which led us to anticipate HYD SYS 1 FAIL. For the time being we monitored. Roughly 10-15 minutes after initially receiving first message the HYD SYS 1 failed. We ran appropriate QRH; ACARS'd company; gave flight attendant a briefing and notified ATC [requesting priority handling]. The rest of the duration of flight continued on without further complications or issues and we ran the QRH for HYD SYS 1 FAIL through its entirety eventually prompting to actuate the free fall lever for landing gear. We landed RWY XXR and rolled to a stop where we were eventually towed to loss of steering.Suggestions: I do not believe there was any negative additions or suggestions I have for this crew and for this situation. All members handled the situation in a calm; professional; and efficient manner all while operating under company SOP. Additionally the passengers were informed in a manner that kept them calm and informed.
During cruise we received a HYD1 LO QTY indication on the EICAS. QRH (EAP 10-8) directed to MONITOR and we noted indication on the MFD (Multi-Function Flight Display) systems page showed quantity in the amber. The FO and I discussed the procedures and began prepping in the event of failure. The flight attendant was notified and we talked through the likely outcomes. We maintained a speed below 250kts and at approx XA30 the EICAS alerted HYD SYS 1 FAIL; we completed the QRH actions; conducted a briefing with the FA (Flight Attendant); notified the company and [requested priority handling] with ATC in accordance with procedures; at this stage we had already commenced the initial descent from FL330. Passengers were notified of the abnormality and assured; without raising alarm; we would continue to ZZZ to make a normal landing. At this point we exchanged controls. Weather at the field was good and we received a visual approach for [Runway] XXR. Tower was informed we would complete a full stop on the runway and need to be towed to the gate. Manual gear extension was conducted just prior to the FAF. All QRH procedures and checklists were completed; approach and landing continued without further event. The aircraft was brought to a complete stop abeam [Taxiway] 1 for easy access; emergency services inspected the aircraft and operations coordinated a tug. Fluid was observed dropping from the left engine. We were towed to Gate X for normal deplaning. Throughout the event the crew conducted themselves professionally; exhibited great CRM and coordinated well. Passengers seemed in good spirits when deplaning and expressed their appreciation. Company communications were concise and professional and all parties involved conducted themselves to a high standard.
