Narrative:

During climb out and leveloff at 8000 ft from isp, we received a TA on TCASII, immediately followed by an RA. Fly away guidance commanded a 4000-6000 FPM descent rates on evsi, which required a climb reversal with 20 degrees nose down pitch and idle thrust to comply. Initial investigation indicated RA was caused by a skydiving aircraft descending from altitude after drop. Thankfully other aircraft was equipped with mode C transponder so our TCASII could compute a resolution. Because of haze and steep deck angles, intruding aircraft was not spotted visually. Probably out of view above windshield frame. First officer's reaction time was good in selecting autoplt off and pushing hard over, but because we still had climb energy, descent was slightly delayed, requiring captain to chop thrust from climb to idle as first officer was pushing with both hands and electric trim. Idle thrust also limited negative G loading estimated at 0 because coffee did not spill.

Title: A CLBING CL65RJ ALMOST HIT A DSNDING ACFT THAT WAS INVOLVED IN PARACHUTE JUMPING ACTIVITY. ATC DID NOT CALL THE TFC BUT TCASII DID.

Narrative: DURING CLBOUT AND LEVELOFF AT 8000 FT FROM ISP, WE RECEIVED A TA ON TCASII, IMMEDIATELY FOLLOWED BY AN RA. FLY AWAY GUIDANCE COMMANDED A 4000-6000 FPM DSCNT RATES ON EVSI, WHICH REQUIRED A CLB REVERSAL WITH 20 DEGS NOSE DOWN PITCH AND IDLE THRUST TO COMPLY. INITIAL INVESTIGATION INDICATED RA WAS CAUSED BY A SKYDIVING ACFT DSNDING FROM ALT AFTER DROP. THANKFULLY OTHER ACFT WAS EQUIPPED WITH MODE C XPONDER SO OUR TCASII COULD COMPUTE A RESOLUTION. BECAUSE OF HAZE AND STEEP DECK ANGLES, INTRUDING ACFT WAS NOT SPOTTED VISUALLY. PROBABLY OUT OF VIEW ABOVE WINDSHIELD FRAME. FO'S REACTION TIME WAS GOOD IN SELECTING AUTOPLT OFF AND PUSHING HARD OVER, BUT BECAUSE WE STILL HAD CLB ENERGY, DSCNT WAS SLIGHTLY DELAYED, REQUIRING CAPT TO CHOP THRUST FROM CLB TO IDLE AS FO WAS PUSHING WITH BOTH HANDS AND ELECTRIC TRIM. IDLE THRUST ALSO LIMITED NEGATIVE G LOADING ESTIMATED AT 0 BECAUSE COFFEE DID NOT SPILL.
