Last week they were flying into BRS in an MD. They declared some kind of fuel emergency and got a priority landing. I had to slow down to min clean and stooge around.
They did not declare a PAN or Mayday.
They seemed to be using some obscure terminology about "fuel distress". Their accent was tricky.
Landed without incident and I have no idea of the facts.
I speculated at the time as to why ATC did not force their hand to declare a PAN.
