Narrative:
After hand over to departure control, immediately after takeoff, we were instructed to climb to 6000 ft, turn right heading 220 degrees. Captain read back the instructions 'aircraft X climb 6000 ft, turn right heading 220 degrees.' as we were climbing out of 3000 ft approximately, we received a TA by TCASII, followed shortly by an RA. First officer maneuvered the airplane accordingly to avoid on-coming aircraft. ATC told us that we should have made a left turn rather than a right one. ATC issued us new instructions on heading and altitude. When we were complying with the new instructions, again we encountered another TA and RA to avoid yet another on-coming aircraft immediately after that. Then finally leveled at 2000 ft conflict was clear. I very distinctly heard ATC giving us 6000 ft and a right turn 220 degrees. I also very distinctly heard the captain reading back 6000 ft right turn 220 degrees.

Title: MISCOM BTWN ATC AND AN ACR RESULT IN 2 SUCCESSIVE TCASII RA'S AND ATC CRITICISM OF THE AVOIDANCE MANEUVERS TAKEN.
Narrative: AFTER HAND OVER TO DEP CTL, IMMEDIATELY AFTER TKOF, WE WERE INSTRUCTED TO CLB TO 6000 FT, TURN R HEADING 220 DEGS. CAPT READ BACK THE INSTRUCTIONS 'ACFT X CLB 6000 FT, TURN R HEADING 220 DEGS.' AS WE WERE CLBING OUT OF 3000 FT APPROX, WE RECEIVED A TA BY TCASII, FOLLOWED SHORTLY BY AN RA. FO MANEUVERED THE AIRPLANE ACCORDINGLY TO AVOID ON-COMING ACFT. ATC TOLD US THAT WE SHOULD HAVE MADE A L TURN RATHER THAN A R ONE. ATC ISSUED US NEW INSTRUCTIONS ON HEADING AND ALT. WHEN WE WERE COMPLYING WITH THE NEW INSTRUCTIONS, AGAIN WE ENCOUNTERED ANOTHER TA AND RA TO AVOID YET ANOTHER ON-COMING ACFT IMMEDIATELY AFTER THAT. THEN FINALLY LEVELED AT 2000 FT CONFLICT WAS CLR. I VERY DISTINCTLY HEARD ATC GIVING US 6000 FT AND A R TURN 220 DEGS. I ALSO VERY DISTINCTLY HEARD THE CAPT READING BACK 6000 FT R TURN 220 DEGS.
