Narrative:

Being vectored for visual approach to runway 1R at las. In descent to 8000 ft MSL (set on MCP) and given heading to intercept the las 190 degree radial and then cleared for visual approach. Attempting to use all the automation for the visual approach, ie, heading select, speed control and vertical speed. Forgot to reselect a lower altitude on the MCP and the aircraft leveled off at 8000 ft MSL. I realized that I was now high on glide path and disconnected the autoplt. I accepted a higher than normal descent rate and saw that I would touch down long. The long touchdown was a normal flare and touchdown and rollout to the end of the runway. No brake cooling was required. This aircraft requires the operator to be on top/ahead of the automation at all times. Any lapses puts the operator way behind!

Title: B737 CAPT LANDS LONG AFTER BEING HELD HIGH DURING VECTOR FOR A VISUAL APCH CLOSE IN VECTOR CAUSES HIM TO COME IN WITH A HIGH RATE OF DSCNT.

Narrative: BEING VECTORED FOR VISUAL APCH TO RWY 1R AT LAS. IN DSCNT TO 8000 FT MSL (SET ON MCP) AND GIVEN HDG TO INTERCEPT THE LAS 190 DEG RADIAL AND THEN CLRED FOR VISUAL APCH. ATTEMPTING TO USE ALL THE AUTOMATION FOR THE VISUAL APCH, IE, HDG SELECT, SPD CTL AND VERT SPD. FORGOT TO RESELECT A LOWER ALT ON THE MCP AND THE ACFT LEVELED OFF AT 8000 FT MSL. I REALIZED THAT I WAS NOW HIGH ON GLIDE PATH AND DISCONNECTED THE AUTOPLT. I ACCEPTED A HIGHER THAN NORMAL DSCNT RATE AND SAW THAT I WOULD TOUCH DOWN LONG. THE LONG TOUCHDOWN WAS A NORMAL FLARE AND TOUCHDOWN AND ROLLOUT TO THE END OF THE RWY. NO BRAKE COOLING WAS REQUIRED. THIS ACFT REQUIRES THE OPERATOR TO BE ON TOP/AHEAD OF THE AUTOMATION AT ALL TIMES. ANY LAPSES PUTS THE OPERATOR WAY BEHIND!
