Narrative:
While cruising at FL290 in french airspace, ATC directed an immediate climb. We disconnected the autoplt and climbed. During the climb, we observed visually a TCASII RA directing a descent. As we initiated our descent, we visually acquired the other aircraft above and to the left of us. We descended back to our cruising altitude of FL290. Apparently french ATC directed the other aircraft to descend on another frequency. His aircraft responded to the RA by climbing, against the controller's clearance. We initially had no RA, only controller's clearance/directive to 'climb immediately.' we subsequently had to resolve the visual (no voice warnings) RA guidance to descend, thus the conflict between aircraft.
Original NASA ASRS Text
Title: B767ER CREW WAS ISSUED AN IMMEDIATE CLB, RECEIVED A TCASII RA AND DSNDED. LTSS OCCURRED WITH AN A319.
Narrative: WHILE CRUISING AT FL290 IN FRENCH AIRSPACE, ATC DIRECTED AN IMMEDIATE CLB. WE DISCONNECTED THE AUTOPLT AND CLBED. DURING THE CLB, WE OBSERVED VISUALLY A TCASII RA DIRECTING A DSCNT. AS WE INITIATED OUR DSCNT, WE VISUALLY ACQUIRED THE OTHER ACFT ABOVE AND TO THE L OF US. WE DSNDED BACK TO OUR CRUISING ALT OF FL290. APPARENTLY FRENCH ATC DIRECTED THE OTHER ACFT TO DSND ON ANOTHER FREQ. HIS ACFT RESPONDED TO THE RA BY CLBING, AGAINST THE CTLR'S CLRNC. WE INITIALLY HAD NO RA, ONLY CTLR'S CLRNC/DIRECTIVE TO 'CLB IMMEDIATELY.' WE SUBSEQUENTLY HAD TO RESOLVE THE VISUAL (NO VOICE WARNINGS) RA GUIDANCE TO DSND, THUS THE CONFLICT BTWN ACFT.
