skibeagle,
Just curious to know: are you a pilot? As Basil says one would expect a pilot to be familiar with the term 'bunt', and 6000' generally means 6000 feet above sea level, or 6000 feet QNH or 6000 feet MSL as you may say in the U.S.
I haven't heard 'Pressure Altitude' since I was studying for my PPL so could that be about where you're at my friend?
