Slip and turn
Here we go ... so now we have a fuel pan whch appears to be different to a pan pan pan, which in turn have nothing to do with Mayday mayday mayday or a fuel emergency. Anyone else see the intermittent fog appearing as usual?
Sorry, my earlier comment may have been misleading. There is no such thing as a fuel PAN, all I meant was a PAN PAN PAN which was declared due to fuel levels. Same rules apply! No intermittent fog.
Definition of MAYDAY is
A condition of being threatened by serious and/or imminent danger and of requiring immediate assistance
Of PAN is
A condition concerning the safety of an aircraft or other vehicle or of some person onboard or within sight but which does not require immediate assistance
As before, if you need the assistance i.e. priority approach when you get to the airport and not before then that's a PAN. If you need the assistance now, then that's a MAYDAY.
