Also, whats with people wearing their phones (or blackberries) on their belts with the ringer on the highest volume....
Vibrate? After a day spent teaching in piston twins, you think I can feel anything, let alone hear anything? My POS cell phone doesn't have an indoor detector to know when to go into quiet mode. I'm just happy if the POS cell phone will actually receive 4 out of 5 calls without needing to reboot.
I set it for the ramp and leave it there. If you don't like loud noises, wear ear plugs and get out of aviation.
