A CRJ PLT SUGGESTS USING PREFERENTIAL RWY EXIT NOTIFICATION INSTEAD OF A LAHSO LNDG IN ORDER TO CLARIFY ATC'S NEEDS AND DESIRES.

Narrative

I HAD SOME INTERESTING THOUGHTS ABOUT LAHSO ON MY LAST FLT INTO DCA. LAHSO CAN'T WORK AT DCA AND MANY OTHER ARPTS. THIS IS BECAUSE PLTS ARE RELUCTANT TO ACCEPT A LAHSO CLRNC; EVEN THOUGH IT IS PROBABLY WELL WITHIN THEIR CAPABILITY MOST OF THE TIME. THE STAKES ARE TOO HIGH AND FOR LAHSO YOU MUST BE SURE. I THINK THE FAA SHOULD START A NEW PROGRAM CALLED THE 'PREFERENTIAL RWY EXIT PROGRAM.' HERE IS HOW IT LOOKS IN MY IMAGINATION: AT DCA PREFERENTIAL RWY EXIT POINTS FOR RWY 1 ARE TXWY N AND RWY 33. FOR RWY 19; THEY ARE TXWY F AND RWY 22. DEFINITION: 'A PREFERENTIAL RWY EXIT POINT IS A TXWY OR INTERSECTING RWY THAT ATC PREFERS THE ACFT USE TO EXIT THE LNDG RWY ONCE SAFE TAXI SPD IS REACHED.' ATC LNDG CLRNCS WOULD SOUND LIKE: 'ACR X CLRED TO LAND RWY 1; PREFERENTIAL EXIT AT TXWY N OR RWY 33.' THE READBACK; 'ACR X CLRED TO LAND RWY 1; TXWY N OR RWY 33.' ACCEPTING THIS CLRNC DOES NOT OBLIGATE THE PLT TO TAXI CLR AT A REQUESTED POINT. HE MAY STILL USE THE ENTIRE RWY IF REQUIRED. PREFERENTIAL RWY EXIT PROGRAM DOES 2 THINGS IN DCA: 1) IT GIVES ADVANCED NOTICE OF ATC'S DESIRE. 2) IT ALLOWS THE ACFT TO TAXI CLR ON AN INTERSECTING RWY. THIS IS NORMALLY FORBIDDEN WITHOUT A SPECIFIC CLRNC (AIM 4-3-20-A). PREFERENTIAL RWY EXIT PROGRAM WAS IMPLEMENTED WITH A SHORT BULLETIN AND SEVERAL NOTES ON THE DCA ARPT DIAGRAM AND THE APCHS TO RWY 1 AND RWY 19. DARK BLUE TXWY LEAD-OFF CTRLINES FROM THE RWY CTRLINE TO THE PREFERENTIAL RWY EXIT PROGRAM RWY EXIT POINTS WERE PAINTED NEXT TO EXISTING MARKINGS. THE LAST STEP IN IMPLEMENTING THE PROGRAM WOULD BE TO INSTALL DARK BLUE HIGH INTENSITY RECESSED LEAD-OFF LIGHTS EXTENDING FROM THE RWY CTRLINE DOWN THE CTR OF THE PREFERENTIAL RWY EXIT PROGRAM RWY EXIT POINTS. THEY WOULD BE VISIBLE ON FINAL APCH AND FLASH IN SEQUENCE IN THE DIRECTION OF RWY EXIT. THEY WOULD BE CTLED BY THE TWR AND ONCE INSTALLED COULD BE SUBSTITUTED FOR THE VERBAL PREFERENTIAL RWY EXIT PROGRAM CLRNC DESCRIBED ABOVE. RWY 18C AT CVG WOULD ALSO USE PREFERENTIAL RWY EXIT PROGRAM AT TXWYS K AND J. SEVERAL OTHER LARGE ARPTS WOULD ALSO USE PREFERENTIAL RWY EXIT PROGRAM.
