Narrative:

Autoplt on, first officer flying, tracking localizer under VFR conditions. Exactly at same time as issued clearance below 10000 ft, TCASII advisory, 'semi-resolution' ie, 'monitor vertical speed' aural, but no 'descend, descend' occurred. Traffic was 500 ft above us. First officer began a gentle descent out of 10000 ft, but was still at 320 KTS airspeed. I repeatedly suggested that he slow to 250 KTS, and he seemed to be attempting to do so, but instead of leveling off to slow down, his commands to the autoplt effected further descent toward 'cleared' altitude, thus little or no deceleration. I put up with this for a short time, all the while telling him to select 'altitude hold' so as to leveloff, slow down. When it became apparent that he could not seem to make the autoplt do this, I extended the speed brakes to slow the airplane down. I stated to him that 'this is a violation of an far.' ultimately, he got the autoplt to begin slowing down the aircraft, but not until reaching approximately 7000 ft! Obviously, I should have said 'I have the airplane' and leveled it off -- manually if necessary, but I was, I suppose, in utter disbelief that an air carrier pilot would so blatantly ignore the 250 KT below 10000 ft rule. This particular pilot would always seem to take great offense at any 'interference' that I might cause to his flying, and this probably contributed to my reluctance to take more immediate action to prevent this 'faux pas.' in the future, I will be more 'direct' in my efforts to ensure FAA compliance by this or any other first officer! So much for trying to be 'mr nice guy!'

Title: FLC OF LGT FAILS TO SLOW TO 250 KIAS DSNDING BELOW 10000 FT MSL AT PBI.

Narrative: AUTOPLT ON, FO FLYING, TRACKING LOC UNDER VFR CONDITIONS. EXACTLY AT SAME TIME AS ISSUED CLRNC BELOW 10000 FT, TCASII ADVISORY, 'SEMI-RESOLUTION' IE, 'MONITOR VERT SPD' AURAL, BUT NO 'DSND, DSND' OCCURRED. TFC WAS 500 FT ABOVE US. FO BEGAN A GENTLE DSCNT OUT OF 10000 FT, BUT WAS STILL AT 320 KTS AIRSPD. I REPEATEDLY SUGGESTED THAT HE SLOW TO 250 KTS, AND HE SEEMED TO BE ATTEMPTING TO DO SO, BUT INSTEAD OF LEVELING OFF TO SLOW DOWN, HIS COMMANDS TO THE AUTOPLT EFFECTED FURTHER DSCNT TOWARD 'CLRED' ALT, THUS LITTLE OR NO DECELERATION. I PUT UP WITH THIS FOR A SHORT TIME, ALL THE WHILE TELLING HIM TO SELECT 'ALT HOLD' SO AS TO LEVELOFF, SLOW DOWN. WHEN IT BECAME APPARENT THAT HE COULD NOT SEEM TO MAKE THE AUTOPLT DO THIS, I EXTENDED THE SPD BRAKES TO SLOW THE AIRPLANE DOWN. I STATED TO HIM THAT 'THIS IS A VIOLATION OF AN FAR.' ULTIMATELY, HE GOT THE AUTOPLT TO BEGIN SLOWING DOWN THE ACFT, BUT NOT UNTIL REACHING APPROX 7000 FT! OBVIOUSLY, I SHOULD HAVE SAID 'I HAVE THE AIRPLANE' AND LEVELED IT OFF -- MANUALLY IF NECESSARY, BUT I WAS, I SUPPOSE, IN UTTER DISBELIEF THAT AN ACR PLT WOULD SO BLATANTLY IGNORE THE 250 KT BELOW 10000 FT RULE. THIS PARTICULAR PLT WOULD ALWAYS SEEM TO TAKE GREAT OFFENSE AT ANY 'INTERFERENCE' THAT I MIGHT CAUSE TO HIS FLYING, AND THIS PROBABLY CONTRIBUTED TO MY RELUCTANCE TO TAKE MORE IMMEDIATE ACTION TO PREVENT THIS 'FAUX PAS.' IN THE FUTURE, I WILL BE MORE 'DIRECT' IN MY EFFORTS TO ENSURE FAA COMPLIANCE BY THIS OR ANY OTHER FO! SO MUCH FOR TRYING TO BE 'MR NICE GUY!'
