Narrative:
Loss of hydraulic fluid was indicated on the right hydraulic system of the medium large transport aircraft. Flight proceeding to bos. Arrival WX was fog RVR reported as low as 2200 during 2 approachs which resulted in missed approachs. Due to hydraulic loss, landing gear was left down after initial extension. The landing gear down confign resulted in higher fuel flow than normal. Decision was made to divert to bdl. With fuel quantity decreasing and WX (cloud build-ups) between bos and bdl, decision was made to land at bed which was VFR and readily available. An uneventful ILS approach and landing was made at bed. An emergency was declared and equipment was requested at both bos and bed due to the hydraulic problem.

Title: ACR MLG CAPT UNDERGOING IOE EXPERIENCES HYDRAULIC PROBLEMS AND MISSED APCHS AT BOS DUE WX AT MINIMUMS, ELECTS TO DIVERT TO BED.
Narrative: LOSS OF HYD FLUID WAS INDICATED ON THE R HYD SYS OF THE MLG ACFT. FLT PROCEEDING TO BOS. ARR WX WAS FOG RVR RPTED AS LOW AS 2200 DURING 2 APCHS WHICH RESULTED IN MISSED APCHS. DUE TO HYD LOSS, LNDG GEAR WAS LEFT DOWN AFTER INITIAL EXTENSION. THE LNDG GEAR DOWN CONFIGN RESULTED IN HIGHER FUEL FLOW THAN NORMAL. DECISION WAS MADE TO DIVERT TO BDL. WITH FUEL QUANTITY DECREASING AND WX (CLOUD BUILD-UPS) BTWN BOS AND BDL, DECISION WAS MADE TO LAND AT BED WHICH WAS VFR AND READILY AVAILABLE. AN UNEVENTFUL ILS APCH AND LNDG WAS MADE AT BED. AN EMER WAS DECLARED AND EQUIP WAS REQUESTED AT BOTH BOS AND BED DUE TO THE HYD PROB.
