Aircraft
While in cruise flight; the crew got an EICAS message. The message was hydraulic A volume low. The checklist calls to unload the A hydraulic system. This means that we do not have the A system for landing. The checklist calls for a longer landing distance; less flaps on landing; blow the gear down; and use the emergency brake system for bringing the aircraft to a stop on the runway. We diverted to [an alternate airport] for longer runway/crash fire rescue. We got the aircraft stopped on the runway; and were towed off the runway following the landing.
Cessna 750 Captain reported diverting to an alternate airport after experiencing the loss of the A Hydraulic System.
