Narrative:

Sep/wed/01, I departed lxt, lee summit airport XA30 for a pleasure flight. I flew to 3GV grain valley airport, picked up my daughter and granddaughter for the purpose of taking them to lambert, st louis to connect with the airliner home. I had already talked to FSS that day and WX was no problem for a VFR flight. After departing 3GV I contacted whiteman approach for flight following. The flight went well and we arrived in st louis at approximately XC10. I let my passenger out and started my engine at approximately XC30, upon which time I contacted clearance delivery for flight following back to lxt. Clearance gave me a squawk code and clearance frequency and told me to go to ground control and wait for them to call me before taxiing and to hold on the ramp until I was contacted. Approximately XC35 I was told to taxi to runway 12R and contact the tower when I was ready for departure. I did my run-up and contacted the tower and approximately XC40 was told I was #10-12 in line for departure, at which time I acknowledged. At approximately XD10 after 15-25 takeoffs and lndgs I was told to taxi in position for takeoff runway 12R. I was then, to the best of my understanding, cleared for takeoff and fly runway heading runway 12. Shortly after climbing out, I encountered moderate to severe turbulence from other departing aircraft. I maintained control to the best of my ability and at no time felt I was in any extreme danger, but was still very concerned for our safety. Soon after I was told by tower to contact departure at which time I did so. Shortly after, within a few seconds, I observed an airliner to the right and in front of our aircraft, but not what I would have considered a close encounter from my point of view. I overheard the airliner say something to the effect of a close encounter with a small aircraft at which time departure asked me what my heading was and I told him 120 degrees. He asked if that was what I was told to do. I acknowledged that was what I understood. He then gave me a heading of 170 degrees. I later overheard the airliner pilot say he didn't even believe I had a proper clearance. This was not my first time into class B and in fact I was in lambert the previous week with no problems. If what I understood for my heading was incorrect, it would have been helpful if the tower would have advised me again to take up a heading of 170 degrees before telling me to contact departure, or clearing the jet behind me for takeoff. Until I overheard the controller and airliner talking, I was unaware there was a problem.

Title: A BEECH BONANZA PLT ENCOUNTERS UNFORECASTED TURB.

Narrative: SEP/WED/01, I DEPARTED LXT, LEE SUMMIT ARPT XA30 FOR A PLEASURE FLT. I FLEW TO 3GV GRAIN VALLEY ARPT, PICKED UP MY DAUGHTER AND GRANDDAUGHTER FOR THE PURPOSE OF TAKING THEM TO LAMBERT, ST LOUIS TO CONNECT WITH THE AIRLINER HOME. I HAD ALREADY TALKED TO FSS THAT DAY AND WX WAS NO PROB FOR A VFR FLT. AFTER DEPARTING 3GV I CONTACTED WHITEMAN APCH FOR FLT FOLLOWING. THE FLT WENT WELL AND WE ARRIVED IN ST LOUIS AT APPROX XC10. I LET MY PAX OUT AND STARTED MY ENG AT APPROX XC30, UPON WHICH TIME I CONTACTED CLRNC DELIVERY FOR FLT FOLLOWING BACK TO LXT. CLRNC GAVE ME A SQUAWK CODE AND CLRNC FREQ AND TOLD ME TO GO TO GND CTL AND WAIT FOR THEM TO CALL ME BEFORE TAXIING AND TO HOLD ON THE RAMP UNTIL I WAS CONTACTED. APPROX XC35 I WAS TOLD TO TAXI TO RWY 12R AND CONTACT THE TWR WHEN I WAS READY FOR DEP. I DID MY RUN-UP AND CONTACTED THE TWR AND APPROX XC40 WAS TOLD I WAS #10-12 IN LINE FOR DEP, AT WHICH TIME I ACKNOWLEDGED. AT APPROX XD10 AFTER 15-25 TKOFS AND LNDGS I WAS TOLD TO TAXI IN POS FOR TKOF RWY 12R. I WAS THEN, TO THE BEST OF MY UNDERSTANDING, CLRED FOR TKOF AND FLY RWY HEADING RWY 12. SHORTLY AFTER CLBING OUT, I ENCOUNTERED MODERATE TO SEVERE TURB FROM OTHER DEPARTING ACFT. I MAINTAINED CTL TO THE BEST OF MY ABILITY AND AT NO TIME FELT I WAS IN ANY EXTREME DANGER, BUT WAS STILL VERY CONCERNED FOR OUR SAFETY. SOON AFTER I WAS TOLD BY TWR TO CONTACT DEP AT WHICH TIME I DID SO. SHORTLY AFTER, WITHIN A FEW SECONDS, I OBSERVED AN AIRLINER TO THE R AND IN FRONT OF OUR ACFT, BUT NOT WHAT I WOULD HAVE CONSIDERED A CLOSE ENCOUNTER FROM MY POINT OF VIEW. I OVERHEARD THE AIRLINER SAY SOMETHING TO THE EFFECT OF A CLOSE ENCOUNTER WITH A SMALL ACFT AT WHICH TIME DEP ASKED ME WHAT MY HEADING WAS AND I TOLD HIM 120 DEGS. HE ASKED IF THAT WAS WHAT I WAS TOLD TO DO. I ACKNOWLEDGED THAT WAS WHAT I UNDERSTOOD. HE THEN GAVE ME A HEADING OF 170 DEGS. I LATER OVERHEARD THE AIRLINER PLT SAY HE DIDN'T EVEN BELIEVE I HAD A PROPER CLRNC. THIS WAS NOT MY FIRST TIME INTO CLASS B AND IN FACT I WAS IN LAMBERT THE PREVIOUS WEEK WITH NO PROBS. IF WHAT I UNDERSTOOD FOR MY HEADING WAS INCORRECT, IT WOULD HAVE BEEN HELPFUL IF THE TWR WOULD HAVE ADVISED ME AGAIN TO TAKE UP A HEADING OF 170 DEGS BEFORE TELLING ME TO CONTACT DEP, OR CLRING THE JET BEHIND ME FOR TKOF. UNTIL I OVERHEARD THE CTLR AND AIRLINER TALKING, I WAS UNAWARE THERE WAS A PROB.
