Narrative:

Was initially cleared to runway 33R via runway 10 and told to hold short of runway 33L. Clearance was changed by ground to south taxiway to runway 33R (no hold short instructions given). Slowed up as another aircraft approached and landed on runway 33L (well in front of me), but did not ask ground for permission to taxi past runway 33L approach sign. The sign was different than the mandatory hold sign previously used and I was not aware that it was a mandatory hold until advised by ATC. I apologized to ATC, but was rather flustered by having been told of this. Ran up engine, took of for touch and goes and forgot to call downwind as instructed by tower. Called after turning final for runway 33 and was cleared for touch and go without incident. With regard to the runway 33L approach sign, I am still not sure if a call was required. The airman's information manual seems to indicate that being cleared to a runway would allow the pilot to taxi past other mandatory hold signs (such as the runway 6/24 signs). It should be clarified if ATC must again be contacted at a runway approach sign, when the pilot has been cleared past that point to another runway without any hold short instructions. Callback conversation with reporter revealed the following information: the reporting 'student' has done all of his flying at isp. The taxiway signs have recently been changed to conform to the new sign criteria set by the FAA. Apparently there is no new sign that requires a stop or special permission to pass as there was under the former criteria. Consequently, isp tower still expects traffic to stop at a red sign even though the aircraft has been cleared all the way to the runway. The reporter will call or visit the tower to clear this dichotomy.

Title: AN SMA TAXIED PAST A RED SIGN.

Narrative: WAS INITIALLY CLRED TO RWY 33R VIA RWY 10 AND TOLD TO HOLD SHORT OF RWY 33L. CLRNC WAS CHANGED BY GND TO S TXWY TO RWY 33R (NO HOLD SHORT INSTRUCTIONS GIVEN). SLOWED UP AS ANOTHER ACFT APCHED AND LANDED ON RWY 33L (WELL IN FRONT OF ME), BUT DID NOT ASK GND FOR PERMISSION TO TAXI PAST RWY 33L APCH SIGN. THE SIGN WAS DIFFERENT THAN THE MANDATORY HOLD SIGN PREVIOUSLY USED AND I WAS NOT AWARE THAT IT WAS A MANDATORY HOLD UNTIL ADVISED BY ATC. I APOLOGIZED TO ATC, BUT WAS RATHER FLUSTERED BY HAVING BEEN TOLD OF THIS. RAN UP ENG, TOOK OF FOR TOUCH AND GOES AND FORGOT TO CALL DOWNWIND AS INSTRUCTED BY TWR. CALLED AFTER TURNING FINAL FOR RWY 33 AND WAS CLRED FOR TOUCH AND GO WITHOUT INCIDENT. WITH REGARD TO THE RWY 33L APCH SIGN, I AM STILL NOT SURE IF A CALL WAS REQUIRED. THE AIRMAN'S INFO MANUAL SEEMS TO INDICATE THAT BEING CLRED TO A RWY WOULD ALLOW THE PLT TO TAXI PAST OTHER MANDATORY HOLD SIGNS (SUCH AS THE RWY 6/24 SIGNS). IT SHOULD BE CLARIFIED IF ATC MUST AGAIN BE CONTACTED AT A RWY APCH SIGN, WHEN THE PLT HAS BEEN CLRED PAST THAT POINT TO ANOTHER RWY WITHOUT ANY HOLD SHORT INSTRUCTIONS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTING 'STUDENT' HAS DONE ALL OF HIS FLYING AT ISP. THE TXWY SIGNS HAVE RECENTLY BEEN CHANGED TO CONFORM TO THE NEW SIGN CRITERIA SET BY THE FAA. APPARENTLY THERE IS NO NEW SIGN THAT REQUIRES A STOP OR SPECIAL PERMISSION TO PASS AS THERE WAS UNDER THE FORMER CRITERIA. CONSEQUENTLY, ISP TWR STILL EXPECTS TFC TO STOP AT A RED SIGN EVEN THOUGH THE ACFT HAS BEEN CLRED ALL THE WAY TO THE RWY. THE RPTR WILL CALL OR VISIT THE TWR TO CLR THIS DICHOTOMY.
