Narrative:

I landed at king salmon around xa:00 and parked in the southeast transient parking area. At around xb:00, I started the engine and finished my after start checks. I listened to the current ATIS and contacted ground. Weather was VFR, good visibility, and calm winds. Ground asked, which runway we would prefer. I responded that we would like runway 18, as we were headed southbound. Ground responded, 'taxi to runway 18 via bravo.' I started moving towards where I thought I should go to intercept runway 18. At this point, I was looking at the king salmon airport diagram in the FAA alaska terminal procedure book. I was confused because there were no taxiway letter identifiers on the airport diagram. I couldn't find bravo. I grabbed the alaska supplement to see if there was taxiway markings indicated on the diagram in this publication. No taxiway markings were on this diagram, either. The other point of confusion for me was operating at a controled airport without txwys to the end of the runway. I was expecting that taxiway bravo would lead me to the end of runway 18. My (incorrect) understanding of the taxi clearance was that I was cleared to the very end of runway 18 and was cleared to cross runway 29. So, after my short taxi under my confusion of trying to locate taxiway bravo, I ended up taxiing past the hold short lines and onto runway 18. Ground control quickly caught this and said, 'bonanza xx, contact tower!' there was no conflicting traffic that I saw or was aware of. I had the tower frequency in the standby position and quickly switched. Tower issued a takeoff clearance, 'bonanza xx, cleared for takeoff, runway 18 or 36.' I responded that I would like to back taxi to runway 36 (as this was closer). Tower responded with 'bonanza xx, cleared for takeoff runway 36, full length available.' I back taxied and departed runway 36. My confusion happened due to two factors. First, the taxiway markings are missing on the king salmon airport diagram. With this information, I would have been clear navigating to the runway. With the proper information on the airport diagram, I would have had a better lookout for the hold short lines. Second, I had the expectation that with the clearance and the section of the aim, I was going to taxi to the end of runway 18, not an intersection. In the back of my mind, while taxiing, I knew I needed to (and had a taxi clearance) to cross runway 29. Perhaps (although I can't be sure), I thought that the hold short lines were for runway 29, as my expectation was that taxiway bravo would take me to runway 36. I was caught inattentive and should have not been taxiing while unsure of my position. In the future, I will make sure I know where I am and understand exactly what the clearance means. If I am unsure, I will ask for clarification. To prevent this from reoccurring to other pilots in the future, I would make two suggestions. First, add the taxiway markings to the king salmon airport diagram. Second, I believe the controller taxi phraseology would have been much clearer with the taxi instruction, 'taxi to runway 18 intersection via bravo.' callback conversation with reporter revealed the following information: the reporter stated that he was on the east ramp and taxied on what he thought was taxiway B. The reporter was using the FAA/nos airport diagram which indicated no taxiway letters. He assumed that the turn onto runway 36/18 was actually taxiway B and that it would take him to the approach end of runway 18. The reporter admitted that he was confused as to the controllers instructions. He didn't see the hold line for runway 18/36 until the controller informed him that he was across it. At this point the tower said 'your cleared for takeoff, runway your choice.' the reporter chose runway 36 because it was closer. Reporter suggest that controllers be more specific in regards to their taxi instructions.

Title: A BE33 PLT ENTERED RWY 18/36 AT AKN WITHOUT A CLRNC, AND CLAIMS THAT TXWY MARKINGS ARE MISSING ON ARPT DIAGRAM.

Narrative: I LANDED AT KING SALMON AROUND XA:00 AND PARKED IN THE SE TRANSIENT PARKING AREA. AT AROUND XB:00, I STARTED THE ENG AND FINISHED MY AFTER START CHECKS. I LISTENED TO THE CURRENT ATIS AND CONTACTED GND. WEATHER WAS VFR, GOOD VISIBILITY, AND CALM WINDS. GND ASKED, WHICH RWY WE WOULD PREFER. I RESPONDED THAT WE WOULD LIKE RWY 18, AS WE WERE HEADED SOUTHBOUND. GND RESPONDED, 'TAXI TO RWY 18 VIA BRAVO.' I STARTED MOVING TOWARDS WHERE I THOUGHT I SHOULD GO TO INTERCEPT RWY 18. AT THIS POINT, I WAS LOOKING AT THE KING SALMON ARPT DIAGRAM IN THE FAA ALASKA TERMINAL PROC BOOK. I WAS CONFUSED BECAUSE THERE WERE NO TXWY LETTER IDENTIFIERS ON THE ARPT DIAGRAM. I COULDN'T FIND BRAVO. I GRABBED THE ALASKA SUPPLEMENT TO SEE IF THERE WAS TXWY MARKINGS INDICATED ON THE DIAGRAM IN THIS PUBLICATION. NO TXWY MARKINGS WERE ON THIS DIAGRAM, EITHER. THE OTHER POINT OF CONFUSION FOR ME WAS OPERATING AT A CTLED ARPT WITHOUT TXWYS TO THE END OF THE RWY. I WAS EXPECTING THAT TXWY BRAVO WOULD LEAD ME TO THE END OF RWY 18. MY (INCORRECT) UNDERSTANDING OF THE TAXI CLRNC WAS THAT I WAS CLRED TO THE VERY END OF RWY 18 AND WAS CLRED TO CROSS RWY 29. SO, AFTER MY SHORT TAXI UNDER MY CONFUSION OF TRYING TO LOCATE TXWY BRAVO, I ENDED UP TAXIING PAST THE HOLD SHORT LINES AND ONTO RWY 18. GND CTL QUICKLY CAUGHT THIS AND SAID, 'BONANZA XX, CONTACT TWR!' THERE WAS NO CONFLICTING TFC THAT I SAW OR WAS AWARE OF. I HAD THE TWR FREQ IN THE STANDBY POSITION AND QUICKLY SWITCHED. TWR ISSUED A TKOF CLRNC, 'BONANZA XX, CLRED FOR TKOF, RWY 18 OR 36.' I RESPONDED THAT I WOULD LIKE TO BACK TAXI TO RWY 36 (AS THIS WAS CLOSER). TWR RESPONDED WITH 'BONANZA XX, CLRED FOR TKOF RWY 36, FULL LENGTH AVAILABLE.' I BACK TAXIED AND DEPARTED RWY 36. MY CONFUSION HAPPENED DUE TO TWO FACTORS. FIRST, THE TXWY MARKINGS ARE MISSING ON THE KING SALMON ARPT DIAGRAM. WITH THIS INFO, I WOULD HAVE BEEN CLEAR NAVIGATING TO THE RWY. WITH THE PROPER INFO ON THE ARPT DIAGRAM, I WOULD HAVE HAD A BETTER LOOKOUT FOR THE HOLD SHORT LINES. SECOND, I HAD THE EXPECTATION THAT WITH THE CLRNC AND THE SECTION OF THE AIM, I WAS GOING TO TAXI TO THE END OF RWY 18, NOT AN INTERSECTION. IN THE BACK OF MY MIND, WHILE TAXIING, I KNEW I NEEDED TO (AND HAD A TAXI CLRNC) TO CROSS RWY 29. PERHAPS (ALTHOUGH I CAN'T BE SURE), I THOUGHT THAT THE HOLD SHORT LINES WERE FOR RWY 29, AS MY EXPECTATION WAS THAT TXWY BRAVO WOULD TAKE ME TO RWY 36. I WAS CAUGHT INATTENTIVE AND SHOULD HAVE NOT BEEN TAXIING WHILE UNSURE OF MY POSITION. IN THE FUTURE, I WILL MAKE SURE I KNOW WHERE I AM AND UNDERSTAND EXACTLY WHAT THE CLRNC MEANS. IF I AM UNSURE, I WILL ASK FOR CLARIFICATION. TO PREVENT THIS FROM REOCCURRING TO OTHER PLTS IN THE FUTURE, I WOULD MAKE TWO SUGGESTIONS. FIRST, ADD THE TXWY MARKINGS TO THE KING SALMON ARPT DIAGRAM. SECOND, I BELIEVE THE CTLR TAXI PHRASEOLOGY WOULD HAVE BEEN MUCH CLEARER WITH THE TAXI INSTRUCTION, 'TAXI TO RWY 18 INTERSECTION VIA BRAVO.' CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT HE WAS ON THE EAST RAMP AND TAXIED ON WHAT HE THOUGHT WAS TXWY B. THE RPTR WAS USING THE FAA/NOS ARPT DIAGRAM WHICH INDICATED NO TXWY LETTERS. HE ASSUMED THAT THE TURN ONTO RWY 36/18 WAS ACTUALLY TXWY B AND THAT IT WOULD TAKE HIM TO THE APCH END OF RWY 18. THE RPTR ADMITTED THAT HE WAS CONFUSED AS TO THE CTLRS INSTRUCTIONS. HE DIDN'T SEE THE HOLD LINE FOR RWY 18/36 UNTIL THE CTLR INFORMED HIM THAT HE WAS ACROSS IT. AT THIS POINT THE TWR SAID 'YOUR CLRED FOR TKOF, RWY YOUR CHOICE.' THE RPTR CHOSE RWY 36 BECAUSE IT WAS CLOSER. RPTR SUGGEST THAT CTLRS BE MORE SPECIFIC IN REGARDS TO THEIR TAXI INSTRUCTIONS.
