FougaMagister,
Just to set the record straight and keep it technically correct, 'Pan' is actually said 6 times (Pan-Pan, pan-pan, pan-pan) if you are broadcasting an urgency message. I believe it was changed to keep it in line with Mayday so there are 6 syllables in any distress call. At least that's what's in CAP 413.
Safe flying,
PJ
