Is that what you heard Merc pilot? Pretty annoying I'll bet. On approach as well? Ouch.
Most likely that's what it was. I had to ask the cabin crew to check that their phones were switched off and if they could check to see if any pax were visibly using one. I even made a PA to remind pax that its an offence to use their phones in flight but it didn't stop until we were pulling onto the gate.
It was very distracting especially as we were on approach to an extremely busy international airport and the Wx was appalling!
In hindsight I maybe should have filed a report or possibly even an ASR.
I'd always thought that the aircraft intercoms would be protected against it (but in fairness I wasn't flying the latest in 2 winged technology that night!)
