Narrative:
Departed from assigned altitude due to RA from TCASII. Climbing aircraft Y caused alert (may have been caused by high rate of climb by other aircraft). ATC did inquire if target aircraft was maintaining assigned altitude. Couldn't hear response. Had trouble telling ATC of climb because of frequency congestion. In the past, my most common RA situation has been this one. Perhaps the previous rule of climbing at 500 FPM for the last 1000 ft would avoid such TCASII alerts.
Original NASA ASRS Text
Title: ALTDEV ALT EXCURSION BY ACR MDT AFTER RECEIPT OF TCASII RA FROM CLBING OPPOSITE DIRECTION TFC.
Narrative: DEPARTED FROM ASSIGNED ALT DUE TO RA FROM TCASII. CLBING ACFT Y CAUSED ALERT (MAY HAVE BEEN CAUSED BY HIGH RATE OF CLB BY OTHER ACFT). ATC DID INQUIRE IF TARGET ACFT WAS MAINTAINING ASSIGNED ALT. COULDN'T HEAR RESPONSE. HAD TROUBLE TELLING ATC OF CLB BECAUSE OF FREQ CONGESTION. IN THE PAST, MY MOST COMMON RA SIT HAS BEEN THIS ONE. PERHAPS THE PREVIOUS RULE OF CLBING AT 500 FPM FOR THE LAST 1000 FT WOULD AVOID SUCH TCASII ALERTS.
