Narrative:
On very short final we (X) were told by tower, first cleared to land at around 100 ft AGL, then to go around at around 50 ft AGL. The runway was clear, no aircraft on runway. The controller sounded confused. The controller was operating/controling both louisville's runways 35L and 35R. Each runway has its own tower frequency, the controller was simulcasting. I think the controller temporarily lost situational awareness and who was who, and who was where. This seems to be a developing trend throughout the united states, especially at night. At many airports (rfd, sat, abq, mem) the same controller routinely is working approach, tower, ground and clearance. All the while receiving calls on all these frequencys at the same time. Pilots can't tell if they are blocking incoming calls on other frequencys. I predict that this continued undermanning of ATC position may result in an accident. One guy can only do so much at a time.
Original NASA ASRS Text
Title: B757 FLC COMPLIES WITH GAR INSTRUCTIONS. NO APPARENT CONFLICT SEEN. LCL CTLR XMITTING ON MULTIPLE FREQS.
Narrative: ON VERY SHORT FINAL WE (X) WERE TOLD BY TWR, FIRST CLRED TO LAND AT AROUND 100 FT AGL, THEN TO GAR AT AROUND 50 FT AGL. THE RWY WAS CLR, NO ACFT ON RWY. THE CTLR SOUNDED CONFUSED. THE CTLR WAS OPERATING/CTLING BOTH LOUISVILLE'S RWYS 35L AND 35R. EACH RWY HAS ITS OWN TWR FREQ, THE CTLR WAS SIMULCASTING. I THINK THE CTLR TEMPORARILY LOST SITUATIONAL AWARENESS AND WHO WAS WHO, AND WHO WAS WHERE. THIS SEEMS TO BE A DEVELOPING TREND THROUGHOUT THE UNITED STATES, ESPECIALLY AT NIGHT. AT MANY ARPTS (RFD, SAT, ABQ, MEM) THE SAME CTLR ROUTINELY IS WORKING APCH, TWR, GND AND CLRNC. ALL THE WHILE RECEIVING CALLS ON ALL THESE FREQS AT THE SAME TIME. PLTS CAN'T TELL IF THEY ARE BLOCKING INCOMING CALLS ON OTHER FREQS. I PREDICT THAT THIS CONTINUED UNDERMANNING OF ATC POS MAY RESULT IN AN ACCIDENT. ONE GUY CAN ONLY DO SO MUCH AT A TIME.
