Narrative:

After receiving a clearance for an IFR cross country from san luis obispo to montgomery field san diego, I realized that the clearance contained a portion of the flight over the water. This flight over the water was V27 from san marcos VOR to catalina island VOR, then mission bay VOR direct myf. The problem is that my airplane was an small aircraft single engine land, and only after takeoff I really realized that I would not comply with the clearance because I had no floating devices on board. Flying over the left.a. TCA for many times, I knew that in reality that the clearance that was given to me would not be the one I had to fly to san diego. I was sure that from point mugu on, left.a. Approach was going to give me vector over the lax just like many other times I made this flight. I was wrong. I had to fly V27. Then, when I was being handled by point mugu approach, I requested vector by V99, then V25 to seal beach VOR. He was unable to work with left.a. Approach on this clearance. So, I stated I had no floating devices. Then he said he was able to give me vector from point mugu to vny and around left.a. TCA. I studied my charts and I thought I was not going to make this route because I was concerned with fuel required. So, I decided to go on V27. Right before approaching catalina island VOR, I again requested vectors closer to the shore. By then I was being handled by left.a. Approach and the controller was much nicer than the previous one and he was able to work with coastal approach, vector closer to the shore. The funny thing about the flight was that the left.a. Approach said that, 'in the future when you want vector closer to the shore, just make a request.' well, my request was made but never accepted. So what I learned from this flight was that when ground controllers issue a clearance, before the readback, you should look at your maps and see if you are able to make it west/O breaking any regulations.

Title: GA SMA PLT CONCERNED HE FAILED TO COMPLY WITH FEDERAL AVIATION REG IF HE FLEW HIS CLRNC ROUTE VIA V27 TO MYF.

Narrative: AFTER RECEIVING A CLRNC FOR AN IFR XCOUNTRY FROM SAN LUIS OBISPO TO MONTGOMERY FIELD SAN DIEGO, I REALIZED THAT THE CLRNC CONTAINED A PORTION OF THE FLT OVER THE WATER. THIS FLT OVER THE WATER WAS V27 FROM SAN MARCOS VOR TO CATALINA ISLAND VOR, THEN MISSION BAY VOR DIRECT MYF. THE PROBLEM IS THAT MY AIRPLANE WAS AN SMA SINGLE ENG LAND, AND ONLY AFTER TKOF I REALLY REALIZED THAT I WOULD NOT COMPLY WITH THE CLRNC BECAUSE I HAD NO FLOATING DEVICES ON BOARD. FLYING OVER THE L.A. TCA FOR MANY TIMES, I KNEW THAT IN REALITY THAT THE CLRNC THAT WAS GIVEN TO ME WOULD NOT BE THE ONE I HAD TO FLY TO SAN DIEGO. I WAS SURE THAT FROM POINT MUGU ON, L.A. APCH WAS GOING TO GIVE ME VECTOR OVER THE LAX JUST LIKE MANY OTHER TIMES I MADE THIS FLT. I WAS WRONG. I HAD TO FLY V27. THEN, WHEN I WAS BEING HANDLED BY POINT MUGU APCH, I REQUESTED VECTOR BY V99, THEN V25 TO SEAL BEACH VOR. HE WAS UNABLE TO WORK WITH L.A. APCH ON THIS CLRNC. SO, I STATED I HAD NO FLOATING DEVICES. THEN HE SAID HE WAS ABLE TO GIVE ME VECTOR FROM POINT MUGU TO VNY AND AROUND L.A. TCA. I STUDIED MY CHARTS AND I THOUGHT I WAS NOT GOING TO MAKE THIS ROUTE BECAUSE I WAS CONCERNED WITH FUEL REQUIRED. SO, I DECIDED TO GO ON V27. RIGHT BEFORE APCHING CATALINA ISLAND VOR, I AGAIN REQUESTED VECTORS CLOSER TO THE SHORE. BY THEN I WAS BEING HANDLED BY L.A. APCH AND THE CTLR WAS MUCH NICER THAN THE PREVIOUS ONE AND HE WAS ABLE TO WORK WITH COASTAL APCH, VECTOR CLOSER TO THE SHORE. THE FUNNY THING ABOUT THE FLT WAS THAT THE L.A. APCH SAID THAT, 'IN THE FUTURE WHEN YOU WANT VECTOR CLOSER TO THE SHORE, JUST MAKE A REQUEST.' WELL, MY REQUEST WAS MADE BUT NEVER ACCEPTED. SO WHAT I LEARNED FROM THIS FLT WAS THAT WHEN GND CTLRS ISSUE A CLRNC, BEFORE THE READBACK, YOU SHOULD LOOK AT YOUR MAPS AND SEE IF YOU ARE ABLE TO MAKE IT W/O BREAKING ANY REGS.
