Narrative:
On vectors to ILS runway 27 final approach at bos and descending from 6000 ft to 2000 ft MSL. WX was approximately 800-1100 ft cg, light rain, snow, winds 330 degrees at 11 KTS 10 mi visibility. The controller gave us a turn to final right at ripit and asked us to maintain our current speed of 180 KTS. Since we were at the marker, descending, configuring and attempting to capture the GS and localizer, we started slowing to final approach speed in order to realize a stabilized approach. Upon seeing the decrease in our speed, the controller got annoyed and told us that we needed to let him know when we slowed to our approach speed. He also wanted us to call him upon landing.

Title: A B757 CREW SLOWS TO FINAL APCH SPD IN AN EFFORT TO STABILIZE THEIR APCH AT THE OM WITHOUT ADVISING ATC WHO HAD PREVIOUSLY ASKED THEM TO MAINTAIN 180 KTS.
Narrative: ON VECTORS TO ILS RWY 27 FINAL APCH AT BOS AND DSNDING FROM 6000 FT TO 2000 FT MSL. WX WAS APPROX 800-1100 FT CG, LIGHT RAIN, SNOW, WINDS 330 DEGS AT 11 KTS 10 MI VISIBILITY. THE CTLR GAVE US A TURN TO FINAL RIGHT AT RIPIT AND ASKED US TO MAINTAIN OUR CURRENT SPD OF 180 KTS. SINCE WE WERE AT THE MARKER, DSNDING, CONFIGURING AND ATTEMPTING TO CAPTURE THE GS AND LOC, WE STARTED SLOWING TO FINAL APCH SPD IN ORDER TO REALIZE A STABILIZED APCH. UPON SEEING THE DECREASE IN OUR SPD, THE CTLR GOT ANNOYED AND TOLD US THAT WE NEEDED TO LET HIM KNOW WHEN WE SLOWED TO OUR APCH SPD. HE ALSO WANTED US TO CALL HIM UPON LNDG.
