PIC OF MLG TAXIES PAST TXWY A4 AT TUS. ARPT CHART NOTE WARNS OF NOT DOING THIS BUT IT HAPPENED ANYWAY. RPTR CITES LACK OF TXWY SIGN FOR ALERTING FLCS AND THE DESIGN LENGTH OF THE DISPLACED THRESHOLD FOR RWY 11. A POSSIBILITY OF A RWY INCURSION OCCURRED.

Narrative

MANY KNOWN HAZARDS IN AVIATION ARE LISTED IN THE CHARTS. I READ AND EVEN CIRCLED AND HIGHLIGHTED THE TAXI HAZARD AT TUS. I THEN PROCEEDED TO TAXI PAST THE INTXN THAT THE HIGHLIGHTED NOTE SAID I SHOULD NOT TAXI PAST. THIS WAS DONE VERY NATURALLY BECAUSE OF THE CONFIGN OF THE RWY AT TUS. THE RWY 11 HAS SUCH A LONG OVERRUN/DISPLACED THRESHOLD; THAT WHEN YOU GET TO THE HAZARD INTXN (A4) IT LOOKS LIKE YOU ARE ONLY 1/2 WAY TO THE END OF THE RWY. IT IS AN ILLUSION THAT SAYS 'KEEP TAXIING.' THE REAL SOLUTION IS TO PUT A HUGE; VERY NOTICEABLE SIGN AT THE APPROPRIATE SPOT ON THE TXWY. THE TENDENCY TO TAXI PAST IS SO GREAT IT 'NEEDS' A SIGN. THE CHART'S NOTES ARE HELPFUL BUT SOME SCENARIOS NEED MORE SAFEGUARDS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR CALLED BACK AND STATED THAT HE HAD NOT ACTUALLY ENTERED THE CONFINES OF RWY 3/21 AS THE GND CTLR STOPPED HIM IN TIME. HE ALSO FIRMLY STATED THAT THERE WAS NO SIGN ADVISING OF A HOLD SHORT OF RWY 3/21 THAT HE COULD RECALL. FROM THE CTLRS ATTITUDE HE FELT THAT THERE WAS NO PROB AND THEREFORE DID NOT CALL THE CTLR ON THE TELEPHONE AFTER HIS FLT.
