OOPS.... I'm sorry. I did not notice. I thought all you did not have
valid GPS altitude. Reading too fast , But you could change all
those lovely Vs in your file into As. With a proper ASCI editor it
takes all of about 1millisecond. Then it will work.

You could use Flight Display program fromhttp://www.soaringpilotsoftware.com/FDpage.htm
It would let you display the pressure altitude or GPS altitude after
displaying flight on map. You select which one to use in settings.

Ok, I'll bite. *How can I display the flight on a map if it has no GPS
data? *WiIl this software actually work with an IGC file that has no
valid GPS data?
