ACR PIC; AS OBSERVER X; NOTES THAT IN CERTAIN CASES; LNDG ACFT RPTING CLR OF RWY STILL HAVE THEIR TAILS WITHIN THE RWY CONFINES.

Narrative

I WAS NOT ON BOARD THE ACFT I AM DESCRIBING. I AM SURE THE PLTS ON BOARD ARE OBLIVIOUS TO ANY SAFETY HAZARD. I WAS TAXIING TO THE DEICE PAD IN DTW; WHEN I HEARD ANOTHER ACFT RPT ON GND CTL 'XXXX CLR OF RWY 3L FOR GATE YYYY.' BUT; WHEN I LOOKED OVER; ABOUT 250 YARDS DISTANT; IT WAS CLR THAT XXXX WAS NOT CLR OF RWY 3L. HE HAD TURNED OFF RWY 3L AT (INACTIVE) RWY 9L; AND WITH NO ONE IN HIS WAY; STOPPED DEAD WITH HIS TAIL STILL STICKING OUT INTO THE RWY. IN THE DISTANCE I COULD SEE THE LNDG LIGHTS OF ANOTHER ACFT OVER THE APCH LIGHTS ABOUT TO LAND ON RWY 3L. I HOPE THE DANGER OF THIS SIT IS OBVIOUS TO THE READER. I AM WRITING THIS RPT BECAUSE THIS IS NOT AN ISOLATED INCIDENT. THERE ARE; I'M AFRAID; MANY ATP'S OUT THERE FLYING TRANSPORT ACFT WHO THINK THEY ARE CLR OF THE ACTIVE RWY IF THE COCKPIT IS ACROSS THE RWY EDGE LIGHTS. THEY ARE MORE WORRIED ABOUT BLOCKING A TXWY THAN BEING STRUCK BY A LNDG OR DEPARTING B757. WE NEED AN EDUCATIONAL PROGRAM TO REMEDY THIS AND EMPHASIZE THAT TAXIING ACFT SHOULD GIVE WAY TO ACFT CLRING THE RWY.
