Narrative:

We were on climb out from vny on the newhall 6 departure under socal control on a 310 degree heading to intercept the pmd 218 degree radial with the autoplt engaged. We had the FMS selected on heading with navigation armed to intercept the course. While on this heading, the controller asked why we had filed through restr airspace. We told the controller that our dispatchers had filed our flight plan and that we would discuss it with them. The controller didn't seem satisfied with that. The controller told us to turn to a 270 degree heading, which we did. A short time later, he gave us a 290 degree heading which was set under the heading bug. While discussing the issue of the restr airspace, the FMS intercepted the 218 degree radial and started a right turn away from 290 degrees. When I realized that we were turning, I initiated a left turn back to 290 degrees. While in this turn, the controller asked what heading we were on and we replied that we were rolling out on a 290 degree heading. The controller then cleared us direct to lando. We asked the controller to confirm the spelling of lando and once confirmed we turned back to the right, rolling out on direct course of 320 degrees to lando. We were somewhat confused about the clearance and queried the controller about it. He confirmed direct to lando direct fmg direct sun. We were then sent to ZLA. When we checked in with ZLA, we were cleared direct to sun. This clearance paralleled our original flight plan clearance and took us through the same restr areas that the socal controller questioned us about. The socal controller's question about restr airspace distraction us during a critical phase of flight when we were responding to several quick changes to heading and course. Since the military airspace was not in use and we were cleared through the airspace on our initial clearance and also with a clearance from ZLA, the questioning by socal departure seemed unnecessary and untimely. An initial statement to check our flight planning was appropriate but a continued discussion about the restr airspace was unnecessary.

Title: C750 DEPARTING VNY EXPERIENCED CONFUSION WITH ATC RESTR AREA REGARDING FILED CLRNC.

Narrative: WE WERE ON CLBOUT FROM VNY ON THE NEWHALL 6 DEP UNDER SOCAL CTL ON A 310 DEG HDG TO INTERCEPT THE PMD 218 DEG RADIAL WITH THE AUTOPLT ENGAGED. WE HAD THE FMS SELECTED ON HDG WITH NAV ARMED TO INTERCEPT THE COURSE. WHILE ON THIS HDG, THE CTLR ASKED WHY WE HAD FILED THROUGH RESTR AIRSPACE. WE TOLD THE CTLR THAT OUR DISPATCHERS HAD FILED OUR FLT PLAN AND THAT WE WOULD DISCUSS IT WITH THEM. THE CTLR DIDN'T SEEM SATISFIED WITH THAT. THE CTLR TOLD US TO TURN TO A 270 DEG HDG, WHICH WE DID. A SHORT TIME LATER, HE GAVE US A 290 DEG HDG WHICH WAS SET UNDER THE HDG BUG. WHILE DISCUSSING THE ISSUE OF THE RESTR AIRSPACE, THE FMS INTERCEPTED THE 218 DEG RADIAL AND STARTED A R TURN AWAY FROM 290 DEGS. WHEN I REALIZED THAT WE WERE TURNING, I INITIATED A L TURN BACK TO 290 DEGS. WHILE IN THIS TURN, THE CTLR ASKED WHAT HDG WE WERE ON AND WE REPLIED THAT WE WERE ROLLING OUT ON A 290 DEG HDG. THE CTLR THEN CLRED US DIRECT TO LANDO. WE ASKED THE CTLR TO CONFIRM THE SPELLING OF LANDO AND ONCE CONFIRMED WE TURNED BACK TO THE R, ROLLING OUT ON DIRECT COURSE OF 320 DEGS TO LANDO. WE WERE SOMEWHAT CONFUSED ABOUT THE CLRNC AND QUERIED THE CTLR ABOUT IT. HE CONFIRMED DIRECT TO LANDO DIRECT FMG DIRECT SUN. WE WERE THEN SENT TO ZLA. WHEN WE CHKED IN WITH ZLA, WE WERE CLRED DIRECT TO SUN. THIS CLRNC PARALLELED OUR ORIGINAL FLT PLAN CLRNC AND TOOK US THROUGH THE SAME RESTR AREAS THAT THE SOCAL CTLR QUESTIONED US ABOUT. THE SOCAL CTLR'S QUESTION ABOUT RESTR AIRSPACE DISTR US DURING A CRITICAL PHASE OF FLT WHEN WE WERE RESPONDING TO SEVERAL QUICK CHANGES TO HDG AND COURSE. SINCE THE MIL AIRSPACE WAS NOT IN USE AND WE WERE CLRED THROUGH THE AIRSPACE ON OUR INITIAL CLRNC AND ALSO WITH A CLRNC FROM ZLA, THE QUESTIONING BY SOCAL DEP SEEMED UNNECESSARY AND UNTIMELY. AN INITIAL STATEMENT TO CHK OUR FLT PLANNING WAS APPROPRIATE BUT A CONTINUED DISCUSSION ABOUT THE RESTR AIRSPACE WAS UNNECESSARY.
