Flight Crew Human Performance
I was working both east and west arrival position when air carrier X called inbound from the northwest on the GQE3 arrival. I assigned air carrier X runway 18L and asked if they had ATIS information. Air carrier X responded that my transmission was broken. I attempted to make my initial transmission again; and air carrier X responded again that my transmission was broken. I had 4 other arrs inbound for mem and 2 aircraft inbound for a satellite airport (olv) and another aircraft trying to check in off another satellite airport (awm) and a VFR overflt. I went to clean up some of that traffic; but each time I transmitted to another aircraft; air carrier X responded that my xmissions were broken. My aircraft were split among 2 different frequencys; so some of the readbacks were stepped on; and others were difficult to hear because of air carrier X. Finally; air carrier X's xmissions caused enough of a disturbance that I asked the supervisor to split the arrs and get me some help. By the end of the briefing to the other controller taking the other arrival; air carrier X had figured out that it was their radio causing the problem and they had fixed the problem. I understand that equipment problems will happen; but pilots need to realize that they are likely not the only aircraft on a given frequency. Air carrier X's attempts to establish communication without any regard for other aircraft made my traffic situation much more difficult than it needed to be.
Original NASA ASRS Text
Title: MEM CONTROLLER DESCRIBED AN ARRIVAL AIRCRAFT FREQUENCY PROBLEM THAT COMPLICATED A COMBINED POSITION OPERATION WHEN A FLIGHT CREW MADE REPEATED CALLS TO ESTABLISH COMMUNICATIONS.
Narrative: I WAS WORKING BOTH E AND W ARR POS WHEN ACR X CALLED INBOUND FROM THE NW ON THE GQE3 ARR. I ASSIGNED ACR X RWY 18L AND ASKED IF THEY HAD ATIS INFO. ACR X RESPONDED THAT MY XMISSION WAS BROKEN. I ATTEMPTED TO MAKE MY INITIAL XMISSION AGAIN; AND ACR X RESPONDED AGAIN THAT MY XMISSION WAS BROKEN. I HAD 4 OTHER ARRS INBOUND FOR MEM AND 2 ACFT INBOUND FOR A SATELLITE ARPT (OLV) AND ANOTHER ACFT TRYING TO CHK IN OFF ANOTHER SATELLITE ARPT (AWM) AND A VFR OVERFLT. I WENT TO CLEAN UP SOME OF THAT TFC; BUT EACH TIME I XMITTED TO ANOTHER ACFT; ACR X RESPONDED THAT MY XMISSIONS WERE BROKEN. MY ACFT WERE SPLIT AMONG 2 DIFFERENT FREQS; SO SOME OF THE READBACKS WERE STEPPED ON; AND OTHERS WERE DIFFICULT TO HEAR BECAUSE OF ACR X. FINALLY; ACR X'S XMISSIONS CAUSED ENOUGH OF A DISTURBANCE THAT I ASKED THE SUPVR TO SPLIT THE ARRS AND GET ME SOME HELP. BY THE END OF THE BRIEFING TO THE OTHER CTLR TAKING THE OTHER ARR; ACR X HAD FIGURED OUT THAT IT WAS THEIR RADIO CAUSING THE PROB AND THEY HAD FIXED THE PROB. I UNDERSTAND THAT EQUIP PROBS WILL HAPPEN; BUT PLTS NEED TO REALIZE THAT THEY ARE LIKELY NOT THE ONLY ACFT ON A GIVEN FREQ. ACR X'S ATTEMPTS TO ESTABLISH COM WITHOUT ANY REGARD FOR OTHER ACFT MADE MY TFC SITUATION MUCH MORE DIFFICULT THAN IT NEEDED TO BE.
