DCA: late takeoff & go-around due to radio interference
(1/1)
eboelter:
KDCA tower at 1950 UTC on 9 January 2019
VASAviation:
Thank you for sharing, eboelter.
Is it known the cause of the interference? It sounds like a hot mic at some point but I'm not really sure.
flyflyfly:
Certainly sounded like a hot mike. You can hear the usual humming sound of two transmitters interfering. Also, there's some background noise suggesting it's a hot mike.
The hot mike could have been in 5512, the aircraft sitting on the runway waiting for its takeoff clearance: after the event they said "5512, we never heard *any* transmission...". Well, when there's a hot mike, there's usually only exactly one aircraft which did not hearing anything... :-) Everyone else would at least have heard some humming and garbled comms...
eboelter:
I wasn't clear what the tower meant by his reference to working a helicopter and it being an issue at "local control". I wonder if light guns were used at any point?
Also, unrelated, it seems to me KDCA is using runway 4 more frequently. I'd be curious to find out how its use is determined if anyone knows.
