Narrative:

We called the direct 800 number for socal departure. I ws told that there was no flight plan in the system. The company usually files the flight plans for us. Since we already were in the airplane and had taxied to the departure end of the runway, I asked if we could get a local clearance to get us going since we were already 25 mins behind the schedule. I was told that they were too busy to do this for us. The controller did suggest that he could give us a clearance to get on top if we were willing to cancel once in VMC and work it out with ZLA to obtain the IFR that would get us to the destination. I consented to this. Took off with a local clearance to climb and maintain 3000 ft MSL. On the climb out, socal gave us the clearance to climb and maintain 15000 ft MSL. Shortly thereafter we were asked if we were in VMC. Since we were, I replied yes. They then asked for a cancellation, told us to squawk a new code and proceed VFR on course, and contact ZLA. I contacted ZLA, gave our altitude climbing to, and approximately heading. They proceeded working with us to get an IFR flight plan in the system. Finally, we were given a clearance to our destination of pae. Looking back at this situation, I would never attempt this again without having a better knowledge of the airspace that would be around us. Prior to this hasty departure, we had never consulted the charts to see where lax class B airspace was in relation to us. For all I know is that we may have possibly inadvertently entered the airspace at lax while we were VFR until getting the IFR from ZLA. The airplane we fly has a great climb rate and got us up to 15000 ft MSL quickly, however, that is not a good reason to take off without consulting the charts. Also, looking at the IFR charts one sees a lot of warning area airspace off of the coast. We could have been in a potential position that we would rather not have wanted to be in, since we had no NOTAMS in regards to this airspace. In the future, if there is no flight plan in the system and ATC is too busy to work one in for me. I will call FSS and have one filed with them officially. Also when in busy and unfamiliar airspace, I will make sure the charts are reviewed before letting late departures cause me to rush and take off when not fully ready.

Title: C750 BUSINESS JET CAPT CONCERNED THAT HE COULD HAVE ENTERED CLASS B AIRSPACE WHILE VFR WAITING FOR IFR CLRNC.

Narrative: WE CALLED THE DIRECT 800 NUMBER FOR SOCAL DEP. I WS TOLD THAT THERE WAS NO FLT PLAN IN THE SYS. THE COMPANY USUALLY FILES THE FLT PLANS FOR US. SINCE WE ALREADY WERE IN THE AIRPLANE AND HAD TAXIED TO THE DEP END OF THE RWY, I ASKED IF WE COULD GET A LCL CLRNC TO GET US GOING SINCE WE WERE ALREADY 25 MINS BEHIND THE SCHEDULE. I WAS TOLD THAT THEY WERE TOO BUSY TO DO THIS FOR US. THE CTLR DID SUGGEST THAT HE COULD GIVE US A CLRNC TO GET ON TOP IF WE WERE WILLING TO CANCEL ONCE IN VMC AND WORK IT OUT WITH ZLA TO OBTAIN THE IFR THAT WOULD GET US TO THE DEST. I CONSENTED TO THIS. TOOK OFF WITH A LCL CLRNC TO CLB AND MAINTAIN 3000 FT MSL. ON THE CLBOUT, SOCAL GAVE US THE CLRNC TO CLB AND MAINTAIN 15000 FT MSL. SHORTLY THEREAFTER WE WERE ASKED IF WE WERE IN VMC. SINCE WE WERE, I REPLIED YES. THEY THEN ASKED FOR A CANCELLATION, TOLD US TO SQUAWK A NEW CODE AND PROCEED VFR ON COURSE, AND CONTACT ZLA. I CONTACTED ZLA, GAVE OUR ALT CLBING TO, AND APPROX HDG. THEY PROCEEDED WORKING WITH US TO GET AN IFR FLT PLAN IN THE SYS. FINALLY, WE WERE GIVEN A CLRNC TO OUR DEST OF PAE. LOOKING BACK AT THIS SIT, I WOULD NEVER ATTEMPT THIS AGAIN WITHOUT HAVING A BETTER KNOWLEDGE OF THE AIRSPACE THAT WOULD BE AROUND US. PRIOR TO THIS HASTY DEP, WE HAD NEVER CONSULTED THE CHARTS TO SEE WHERE LAX CLASS B AIRSPACE WAS IN RELATION TO US. FOR ALL I KNOW IS THAT WE MAY HAVE POSSIBLY INADVERTENTLY ENTERED THE AIRSPACE AT LAX WHILE WE WERE VFR UNTIL GETTING THE IFR FROM ZLA. THE AIRPLANE WE FLY HAS A GREAT CLB RATE AND GOT US UP TO 15000 FT MSL QUICKLY, HOWEVER, THAT IS NOT A GOOD REASON TO TAKE OFF WITHOUT CONSULTING THE CHARTS. ALSO, LOOKING AT THE IFR CHARTS ONE SEES A LOT OF WARNING AREA AIRSPACE OFF OF THE COAST. WE COULD HAVE BEEN IN A POTENTIAL POS THAT WE WOULD RATHER NOT HAVE WANTED TO BE IN, SINCE WE HAD NO NOTAMS IN REGARDS TO THIS AIRSPACE. IN THE FUTURE, IF THERE IS NO FLT PLAN IN THE SYS AND ATC IS TOO BUSY TO WORK ONE IN FOR ME. I WILL CALL FSS AND HAVE ONE FILED WITH THEM OFFICIALLY. ALSO WHEN IN BUSY AND UNFAMILIAR AIRSPACE, I WILL MAKE SURE THE CHARTS ARE REVIEWED BEFORE LETTING LATE DEPS CAUSE ME TO RUSH AND TAKE OFF WHEN NOT FULLY READY.
