Quick question re:emergency squawks

[E-n-i-g-m-a-8-3]

what's this term medical emergency by the way??? its a pan a mayday or its nowt but an attempt to get to ones original destination first. medical emergency but I'll fly past lots of suitable airports is obviously not an emergency in the first place

Maybe there is a medical emergency on board which requires the urgent assistance of somebody on the ground at the original destination, and the pilot is just declaring the 'medical emergency' so as to have priority over other traffic in the vicinity...

I guess you call the Pan first and then when asked about the nature of the emergency you declare it as medical. That way ATC know you're aircraft is technically OK but you require assistance for an expeditious approach, and to be met by medical services.
