Narrative:

At the oakland airport; I was cleared to runway 27R from the FBO. I swung onto the parallel taxiway and was maintaining my nosewheel on the center line of the taxiway. I had gone very few feet when I noticed that my right wing was partially over the runway boundary line. Surprised is an understatement. I had anticipated seeing the boundary line in front of my aircraft; not slowly converging from a very acute angle onto the taxiway from the right. I quickly did a 360 degree turn to the left to clear the boundary line and moved to the far left of the taxiway -- off the center line. There was no inbound traffic to either runway 27L or right at the time so I do not think the tower was overly concerned; or else their attention was elsewhere (I think watching two banner towing aircraft in their airspace). Later; after studying the satellite image display of that end of the runway; two things come to mind. First; I am sure that I am not the only one that has done that. And two; I don't know how I would cure the problem. Plainly; there is insufficient space for all the activities in that area.

Title: GA PILOT REPORTS INADVERTENTLY CROSSING HOLD SHORT LINE FOR RWY 27R AT OAK DUE TO ACUTE ANGLE OF APPROACH.

Narrative: AT THE OAKLAND AIRPORT; I WAS CLEARED TO RUNWAY 27R FROM THE FBO. I SWUNG ONTO THE PARALLEL TAXIWAY AND WAS MAINTAINING MY NOSEWHEEL ON THE CENTER LINE OF THE TAXIWAY. I HAD GONE VERY FEW FEET WHEN I NOTICED THAT MY RIGHT WING WAS PARTIALLY OVER THE RUNWAY BOUNDARY LINE. SURPRISED IS AN UNDERSTATEMENT. I HAD ANTICIPATED SEEING THE BOUNDARY LINE IN FRONT OF MY AIRCRAFT; NOT SLOWLY CONVERGING FROM A VERY ACUTE ANGLE ONTO THE TAXIWAY FROM THE RIGHT. I QUICKLY DID A 360 DEG TURN TO THE LEFT TO CLEAR THE BOUNDARY LINE AND MOVED TO THE FAR LEFT OF THE TAXIWAY -- OFF THE CENTER LINE. THERE WAS NO INBOUND TRAFFIC TO EITHER RWY 27L OR R AT THE TIME SO I DO NOT THINK THE TOWER WAS OVERLY CONCERNED; OR ELSE THEIR ATTENTION WAS ELSEWHERE (I THINK WATCHING TWO BANNER TOWING AIRCRAFT IN THEIR AIRSPACE). LATER; AFTER STUDYING THE SATELLITE IMAGE DISPLAY OF THAT END OF THE RUNWAY; TWO THINGS COME TO MIND. FIRST; I AM SURE THAT I AM NOT THE ONLY ONE THAT HAS DONE THAT. AND TWO; I DON'T KNOW HOW I WOULD CURE THE PROBLEM. PLAINLY; THERE IS INSUFFICIENT SPACE FOR ALL THE ACTIVITIES IN THAT AREA.
