A-81-134
NTSB Safety Recommendation — Aviation
Recommendation text
BASED ON INFORMATION CONTAINED WITHIN SPECIAL INVESTIGATION REPORT NTSB-SIR-81-6, THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REDESIGN THE LOW ALTITUDE/CONFLICT ALERT AT ARTS III FACILITIES SO THAT THE AUDIO SIGNAL ASSOCIATED WITH THE LOW ALTITUDE ALERT IS READILY DISTINGUISHABLE FROM THAT ASSOCIATED WITH THE CONFLICT ALERT AND HEARD ONLY BY CONTROLLERS IMMEDIATELY CONCERNED WITH THE INVOLVED AIRCRAFT.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to redesign the Low Altitude/Conflict Alert at ARTS III facilities so that the audio signal for the low altitude alert is clearly different from the conflict alert and is heard only by controllers directly handling the involved aircraft.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
