Narrative:
Flight was in cruise and on a heading assigned by ATC to intercept arrival southeast of vhp VOR. TCASII TA of 'traffic, traffic' received. Captain and I started to look for traffic. Before I could visually acquire traffic, we received a TCASII RA of 'climb, climb' followed by a command of 2000 FPM climb. I disengaged autoplt but not autothrottles and shifted to instruments to follow RA. As we were passing through FL214, captain saw traffic and told me to 'keep climbing.' ATC notified at FL216 of our following a TCASII RA. ATC replied 'don't go too high, you have traffic at FL220 at 12 O'clock position.' captain asked if I saw either traffic. 'No' I said. Captain assumed control of aircraft and returned to FL210. My first RA in 10 yrs of commercial flying and system worked as advertised. No complaints from either the flight attendants or passenger. Next time will disengage autothrottles, too, as they had a hard time keeping up with what we wanted to do and actually made more work for us in trying to keep evasive maneuver smooth to prevent injury to folks in back.
Original NASA ASRS Text
Title: B737-200 CREW HAD LESS THAN LEGAL SEPARATION IN ZID CLASS A AIRSPACE.
Narrative: FLT WAS IN CRUISE AND ON A HDG ASSIGNED BY ATC TO INTERCEPT ARR SE OF VHP VOR. TCASII TA OF 'TFC, TFC' RECEIVED. CAPT AND I STARTED TO LOOK FOR TFC. BEFORE I COULD VISUALLY ACQUIRE TFC, WE RECEIVED A TCASII RA OF 'CLB, CLB' FOLLOWED BY A COMMAND OF 2000 FPM CLB. I DISENGAGED AUTOPLT BUT NOT AUTOTHROTTLES AND SHIFTED TO INSTS TO FOLLOW RA. AS WE WERE PASSING THROUGH FL214, CAPT SAW TFC AND TOLD ME TO 'KEEP CLBING.' ATC NOTIFIED AT FL216 OF OUR FOLLOWING A TCASII RA. ATC REPLIED 'DON'T GO TOO HIGH, YOU HAVE TFC AT FL220 AT 12 O'CLOCK POS.' CAPT ASKED IF I SAW EITHER TFC. 'NO' I SAID. CAPT ASSUMED CTL OF ACFT AND RETURNED TO FL210. MY FIRST RA IN 10 YRS OF COMMERCIAL FLYING AND SYS WORKED AS ADVERTISED. NO COMPLAINTS FROM EITHER THE FLT ATTENDANTS OR PAX. NEXT TIME WILL DISENGAGE AUTOTHROTTLES, TOO, AS THEY HAD A HARD TIME KEEPING UP WITH WHAT WE WANTED TO DO AND ACTUALLY MADE MORE WORK FOR US IN TRYING TO KEEP EVASIVE MANEUVER SMOOTH TO PREVENT INJURY TO FOLKS IN BACK.
