CAPT OF AN MLG ACR ACFT IS CONCERNED WITH REGARD TO THE CLOSE PROX OF CROSS LNDG TFC DURING APCH TO LAND.

Narrative

UPON BEING CLRED FOR A VISUAL APCH TO RWY 23 (10 NM OUT) WE (ACR X) WERE CLRED TO LAND. WE WERE TOLD TO SLOW TO 190 KTS; 170 KTS; AND FINAL APCH SPDS; IN ORDER TO ACCOMMODATE A LIGHT (SMA SEL) LNDG ON THE XING RWY 18L. THE RWYS CROSS AT 2000 FT DOWN BOTH RWYS. WE WERE IN VISUAL CONDITIONS BUT WERE UNABLE TO SPOT THE SMA Y UNTIL WE WERE BELOW 100 FT SHORT FINAL AND HE WAS XING THE NUMBERS FOR RWY 18L. WE NEVER CALLED HIM IN SIGHT. EACH TIME WE WERE TOLD TO SLOW; WE SLOWED 10-15 KTS SLOWER THAN ASSIGNED. THE SMA Y WAS TOLD TO FOLLOW ON THROUGH THE INTXN AND KEEP HIS SPD UP. UPON SIGHTING HIM; SHOULD WE HAVE CHOSEN TO GAR OR TOLD TO GAR; AN UNSAFE SIT WOULD HAVE DEVELOPED AS WE WOULD HAVE LOST SIGHT OF HIM UNDER THE NOSE. WE CONTINUED; BUT AN EXTREMELY TIGHT LNDG SIT OCCURRED. WE ESTIMATE THAT HE WAS XING OUR RWY ON HIS LNDG ROLL AS WE WERE LESS THAN 500 FT FROM THE APCH END OF RWY 23 (APPROX 3000 FT). NO COMMENT WAS MADE BY TWR; AS THIS IS AT TIMES THE TIGHT LNDG CONDITIONS AT SOME ARPTS. I UNDERSTAND THAT TWRS DO AN EXCELLENT JOB ACCOMMODATING LARGE NUMBERS OF ACFT IN SHORT AMOUNTS OF TIME. MY COMPLAINT IS TO THE FREEDOM GIVEN TO SMALL ACFT TO ENDANGER THE SAFETY LEVEL WHILE SEQUENCING JET ACFT. I DON'T CONSIDER THIS SIT AS UNSAFE BUT CONCERN SHOULD BE GIVEN TO MY COMMENTS IN THE PREVIOUS PARAGRAPH.
