Flight numbers?

I realised just now that something I had taken for granted I was familiar with is, now I think about it, not as clear in my head as I thought, so may I ask.... What prefix does ATC (and the pilots) use to identify their flight number. I am not talking about their callsign... For instance, British Ai...

Re: B737 - normal use of DC power knob?

Moving the knob to different positions does not alter anything on the airplane itself, the selector just picks up the DC voltage from the selected bus and indicates the voltage on the display above the knob.
