Hi Jason, I wish you luck. Mike B has tried fighting this one before, and his "Joey" does have the pressure altitude facility. The FAI seems to be paranoid about cheating, so insists on suitable security for the process and the resultant files. The pressure altitude is required because the GPS altitude measurement is (or used to be before the switching off of Selective Availability) not sufficiently accurate, and the height reported by GPS is above the theoretical geoid rather than above MSL. In other words, they needed something like a standard barograph. This question has been done to death on rec.aviation.soaring, so I think any chance of changing the collective mind of FAI-IGC is low. There is no problem, for local contests, for the local rules to allow the use of any GPS arrangements they wish. Some local contests in USA have allowed use of hand held GPS devices which have sufficient track storage to accommodate the duration of the task. Cheers, John G.
