Important Notice when uploading flights to the OLC

During uploading flights = *.igc files to the OLC server somtimes this flights will be marked with "invalid"

There are several reasons this can happen, please take care of:


1. Don't rename the *.igc file of a flight.

2. If the flight looks defect at Flachart or Maxpunkte, please open the flight at the instrument and activate "Recalc Sign" and download the flight again. Take care that there is no other USB software active as mobile phones programs.

3. All flights recorded with the IQ-BASIC-GPS are using a different digital signature as the other Brauniger units! This is causing problems at the OLC server. If such a flight is marked "invalid", please inform the OLC under
