PLT OF C210 HAS DIFFICULTY DURING TAXI SIGHTING THE TXWY MARKINGS DUE TO RAIN AND RESULTING LOW VISIBILITY. HE TAXIES ONTO AN ACTIVE RWY AND HAS A CONFLICT WITH DEPARTING JET ACFT.

Narrative

HOW PROBLEM AROSE. TAXI CLRNC GIVEN TO RWY 9L VIA GOLF; ECHO; KILO. TURNING FROM ECHO TO KILO I NOTED THE DIRECTION ARROW AND FOLLOWED THE YELLOW TAXI LINE TO COMPLETE THE TURN. IN THE RAIN I DID NOT NOTICE OTHER LINES. WHEN LINING UP WITH TXWY KILO I NOTED A LARGE 2 ENG BOEING TAXI TOWARD ME AND A DASH 8 HOLDING TO MY L. I DETERMINED THAT THE BOEING WOULD BE TURNED INTO THE RAMP BEFORE I REACHED THE AREA AND THE DASH 8 WAS WAITING TO BACK TAXI BEHIND ME. I WAS CONSIDERING QUERYING THE STATUS WITH GND CTL BUT BEFORE I COULD I NOTED THAT THE BOEING WAS ACCELERATING AND NOT TURNING. I TOOK EVASIVE ACTION BY MOVING TO THE R. THE BOEING ROTATED IN FRONT OF MY POSITION AND WAS AIRBORNE ABEAM OF ME. IT APPEARED THAT THE BOEING TOOK EVASIVE ACTION BY RAISING ITS L WING. CONTRIBUTING FACTORS: I HAD DECLINED A SHORTER TAXI TO RWY 17 AS IT WOULD HAVE GIVEN ME A QUARTERING TAILWIND. THERE WAS WATER ON THE GND AND POOR LIGHTING. THIS AFFECTED THE VISIBILITY OF PAINTED LINES ON CONCRETE. A TRANSVERSE OR OBLIQUE LINE IS NOT AS EASILY SEEN. THIS AFFECTED MY VIEW OF THE TXWYS AND HAD ME FOLLOWING THE LINE ON TO KILO 2. WHEN TAKING OFF A SHORT WHILE LATER I COULD SEE THAT THE YELLOW LINE ALONG KILO 2 WAS DARKER; POSSIBLY HAVING BEEN REPAINTED. THE HOLD SHORT LINE WAS NOT SEEN DUE TO THE RAIN. PREOCCUPATION WITH THE BOEING AND DASH 8 KEPT ME FROM OBSERVING THE RWY ENVIRONMENT. THE GND CTLR WAS NOT MONITORING MY PROGRESS AND ALSO NOT NOTICED MY INTRUSION ON TO THE RWY. HUMAN PERFORMANCE CONSIDERATIONS. POOR LIGHTING WITH RAIN AND GND WATER AFFECTED VISIBILITY OF THE TXWY LINES AND PERSPECTIVE OF THE RWY TXWY ENVIRONMENT. THE TURN FROM ECHO TO KILO 2 IS ONLY 30 DEGS LESS THAN KILO AND GIVES THE IMPRESSION OF A R ANGLE TURN. PROGRESSIVE TAXI INSTRUCTIONS WOULD HAVE HELPED THE SIT. A DIFFERENT LINE DENOTING TRANSITIONS FROM TXWY TO RWY WAY ALSO ASSIST PLTS WHEN MAKING THIS TRANSITION; SUCH AS AN ALTERNATING YELLOW AND WHITE LINE. WITH REFLECTIVE PAINT; MAY ALSO BE MORE EASILY NOTED AT NIGHT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT HE WAS REQUESTED TO CALL THE TWR WHEN HE REACHED HIS DESTINATION. HE SPOKE TO THE TWR SUPVR WHO WAS CONCERNED ABOUT THE LACK OF VISIBILITY OF THE TXWY MARKING AND DID INDICATE THAT IS A CONFUSING AREA WHEN RAIN AND DIM LIGHTING EXISTS. RPTR DID NOT SEE ANY HOLD LINES AND COULD NOT DIFFERENTIATE BETWEEN THE YELLOW LINES AND ANY OTHER MARKINGS. THE RAIN OBSCURED THEM. HE WAS ACTUALLY ON THE RWY WITH THE BOEING ACFT TAKING OFF OVER HIM. HE HAD MOVED TO THE SIDE OF THE RWY WHEN HE REALIZED THE SIT. LCL CTLR CAME ON FREQ IMMEDIATELY AND RPTR STATED HE REALIZED WHERE HE WAS AND WAS IN THE PROCESS OF TAXIING OFF THE RWY. TWR QUESTIONED IF RPTR WAS OK PHYSICALLY AND EMOTIONALLY AND REMAINED VERY CALM WHICH HELPED THE RPTR. RPTR WAS IN SAT LATER AND NOTED THEY HAD PAINTED A BLACK LINE ON EITHER SIDE OF THE YELLOW MARKINGS WHICH MADE THEM MUCH MORE VISIBLE WHEN PAINTED ON CEMENT. THE HOTLINE WAS RECOMMENDED SO HE COULD VOICE HIS SUGGESTIONS IN THAT FASHION AS WELL.
