How to change the igc flight log time interval on CN2:

CN2 stores logs internally at 1 second. You can d/l to USB at 1, 2, 4 or 10 second intervals.

Please pay close attention to the voice over. There is one especially non-obvious press of the down arrow key.

We think that d/l at 4 second interval solves (really: masks) the discontinuity that occurs when the UTC - GPS time offset update is received from the GPS system.
