Narrative:

The captain was flying, and I was handling the radios. We were given clearance to cross otter intersection at 250 KTS and 11000 ft. The captain started down and was right on profile for a 320 KT descent. At about 13000 ft he slowed the descent and pushed the power up. I told him they wanted us at 250 KTS and 11000 ft at otter intersection and he said they wanted that at bonnr intersection, but for me to verify with approach. I did, and it was otter. The captain told me to tell them that we thought it was bonnr and that we would be fast. They said no problem and that we were not the first to mix these two up. This was only our second leg to fly together (I flew the first leg). The next 2 days of flying together, I observed that it was his style to descend a good bit early for all xings. Thus, what I had thought was a precise descent for otter intersection, was just a coincidence as he was making his standard early descent for bonnr intersection.

Title: AN MLG MISSED HIS AIRSPD RESTRICTION AN AT INTXN ON DSCNT.

Narrative: THE CAPT WAS FLYING, AND I WAS HANDLING THE RADIOS. WE WERE GIVEN CLRNC TO CROSS OTTER INTXN AT 250 KTS AND 11000 FT. THE CAPT STARTED DOWN AND WAS RIGHT ON PROFILE FOR A 320 KT DSCNT. AT ABOUT 13000 FT HE SLOWED THE DSCNT AND PUSHED THE PWR UP. I TOLD HIM THEY WANTED US AT 250 KTS AND 11000 FT AT OTTER INTXN AND HE SAID THEY WANTED THAT AT BONNR INTXN, BUT FOR ME TO VERIFY WITH APCH. I DID, AND IT WAS OTTER. THE CAPT TOLD ME TO TELL THEM THAT WE THOUGHT IT WAS BONNR AND THAT WE WOULD BE FAST. THEY SAID NO PROBLEM AND THAT WE WERE NOT THE FIRST TO MIX THESE TWO UP. THIS WAS ONLY OUR SECOND LEG TO FLY TOGETHER (I FLEW THE FIRST LEG). THE NEXT 2 DAYS OF FLYING TOGETHER, I OBSERVED THAT IT WAS HIS STYLE TO DSND A GOOD BIT EARLY FOR ALL XINGS. THUS, WHAT I HAD THOUGHT WAS A PRECISE DSCNT FOR OTTER INTXN, WAS JUST A COINCIDENCE AS HE WAS MAKING HIS STANDARD EARLY DSCNT FOR BONNR INTXN.
