Narrative:
MD80 cleared to 11000 ft. King air descending to 10000 ft after paradrop at 14500 ft. King air reported at 10000 ft but MD80 had RA causing climb. Problem appears to be that TCASII cannot track extremely fast descending aircraft. Airliner crew upset that they had to deal with RA. Problem compounded by airliner crew not looking out the window, identing traffic, and thus not having to comply with RA. IFR in VFR conditions means VFR -- look out the window.
Original NASA ASRS Text
Title: TCASII RA RESULTS FROM TCASII PERCEIVED CONFLICT BTWN DSNDING ACR AND DSNDING SKYDIVER ACFT.
Narrative: MD80 CLRED TO 11000 FT. KING AIR DSNDING TO 10000 FT AFTER PARADROP AT 14500 FT. KING AIR RPTED AT 10000 FT BUT MD80 HAD RA CAUSING CLB. PROB APPEARS TO BE THAT TCASII CANNOT TRACK EXTREMELY FAST DSNDING ACFT. AIRLINER CREW UPSET THAT THEY HAD TO DEAL WITH RA. PROB COMPOUNDED BY AIRLINER CREW NOT LOOKING OUT THE WINDOW, IDENTING TFC, AND THUS NOT HAVING TO COMPLY WITH RA. IFR IN VFR CONDITIONS MEANS VFR -- LOOK OUT THE WINDOW.
