Good call Genghis,
I have been helped out on more than one occasion by a calm voice who I have never met.
When your head is bouncing off the canopy and you are unable to make contact with any of the buttons on the panel because of turbulence the last thing you need reminding of is the fact that you are on the wrong quadrantal etc...
My favourite 3 controller voices are all based in the Southwest (and Jersey) and would give Mr Kipling a run for his money in the soothing voice stakes.
I am sure the all make exceedingly good cakes also,
