Aircraft; Procedure
Noticed aircraft toward us on the ND. ATC never mentioned aircraft until event had already occurred. After the event occurred he mentioned clear of traffic climb and maintain FL340. When the RA went off we had captured the altitude we were climbing to and we were leveling off. The command bars on our PFD were the same as the aircraft was doing at the same time. Climb rate too great in proximity to other aircraft. Never was made aware of aircraft even though it was noticed on our screen. After event occurred ATC said 'clear of traffic climb and maintain FL340' we [thought] you never mentioned the traffic anyway. Decreased vertical climb as aircraft was capturing altitude we were climbing to. In close proximity to aircraft may need to decrease climb rate even if you think your rate will not set off the RA/TA mode.
Climbing out of Atlanta airspace south of RESPE waypoint to an altitude of FL320 we noticed an aircraft on our TCAS display. We were not notified by ATC of the traffic. As the aircraft was capturing the altitude and was starting to level off our TCAS called out a RA and adjust vertical speed. Since aircraft was leveling off and the reduced pitch mirrored the command bars no real adjustment was required. As aircraft went by us ATC said you are clear of traffic continue climb. We were never made aware of the traffic by ATC to begin with. We climbed to our new assigned altitude and continued flight to our destination with no further problems. Possible ATC overload; no real chatter on the radio; possibly an oversight on his side or he did not think the climb or distance would cause a problem.
B737-700 flight crew experiences a TCAS RA while leveling off at assigned altitude. The target aircraft was assigned and altitude 1;000 feet above and no action was required by the pilot flying as the autopilot leveled the aircraft 1;000 feet below.
