Fredrik,

If you set your 76s to base its altitude as a barometer (auto-calibrate OFF?) and then initialise the height to be 200m lower than the actual height, what values are recorded? ie. will all recorded values be 200m lower than the actual height?

There are actually three altitude systems – Garmins with a pressure sensor record a height based on user calibration, GPS height and pressure readings.

If I use GPSDump to save a tracklog, which one of these systems is recorded, and is it possible to use this tracklog, without conversion, to check for altitude violations based on GPS height or barometric height?

If this cannot be done then I need to use additional software and convert tracklogs – FS / GPSDump does not provide the complete solution that I need.
