Narrative:

After passing wever at 10000 ft, 250 KTS on descent to mia, received late descent from ATC. First officer extended speed brakes, extended flaps 5 degrees, lowered gear and resumed descent to capture GS beneath at 210 KTS. I said 'level off,' intending for him to slow first and extend full flaps before resuming descent. After glancing down to complete landing checks, I noted we were still descending, approaching iness, the OM at 1000 ft still at 210 KTS and the same confign. I gave horizontal hand motion this time, again urging first officer to leveloff and dirty up. After completing checks and receiving landing clearance, GPWS warning 'VMC conditions' sounded. First officer finally levels at 300 ft with red over red VASI and fully configured. We land long and brake hard to meet lahso restrs. First officer explained that in his judgement, aircraft could not be landed unless he continued descent. Captain believes if aircraft had been leveled immediately as directed, normal landing could have been accomplished. In any case, the order to level off should have been observed, thus avoiding the predicament altogether. In face of unresponsive first officer, captain's ordering go around or assuming controls were next best options.

Narrative: AFTER PASSING WEVER AT 10000 FT, 250 KTS ON DSCNT TO MIA, RECEIVED LATE DSCNT FROM ATC. FO EXTENDED SPD BRAKES, EXTENDED FLAPS 5 DEGS, LOWERED GEAR AND RESUMED DSCNT TO CAPTURE GS BENEATH AT 210 KTS. I SAID 'LEVEL OFF,' INTENDING FOR HIM TO SLOW FIRST AND EXTEND FULL FLAPS BEFORE RESUMING DSCNT. AFTER GLANCING DOWN TO COMPLETE LNDG CHKS, I NOTED WE WERE STILL DSNDING, APCHING INESS, THE OM AT 1000 FT STILL AT 210 KTS AND THE SAME CONFIGN. I GAVE HORIZ HAND MOTION THIS TIME, AGAIN URGING FO TO LEVELOFF AND DIRTY UP. AFTER COMPLETING CHKS AND RECEIVING LNDG CLRNC, GPWS WARNING 'VMC CONDITIONS' SOUNDED. FO FINALLY LEVELS AT 300 FT WITH RED OVER RED VASI AND FULLY CONFIGURED. WE LAND LONG AND BRAKE HARD TO MEET LAHSO RESTRS. FO EXPLAINED THAT IN HIS JUDGEMENT, ACFT COULD NOT BE LANDED UNLESS HE CONTINUED DSCNT. CAPT BELIEVES IF ACFT HAD BEEN LEVELED IMMEDIATELY AS DIRECTED, NORMAL LNDG COULD HAVE BEEN ACCOMPLISHED. IN ANY CASE, THE ORDER TO LEVEL OFF SHOULD HAVE BEEN OBSERVED, THUS AVOIDING THE PREDICAMENT ALTOGETHER. IN FACE OF UNRESPONSIVE FO, CAPT'S ORDERING GAR OR ASSUMING CTLS WERE NEXT BEST OPTIONS.
