Narrative:

At cruise flight level, #2 hydraulic system failed (loss fluid/pressure). Crew completed abnormal procedure in manual. Contacted dispatch and maintenance control. Given good WX and number of alternate airports on route and the components actually lost with hydraulic failure. We elected to continue to destination with everyone's approval. Advised ATC of problem and declared an emergency. Flight, approach and landing were all normal otherwise.
