Track Log Settings
Record Mode lets you select one of three track recording options:
‘Off’ – No track log will be recorded.
NOTE: Selecting ‘Off’ will prevent you from using the TracBack feature.
‘Fill’ – A track log will be recorded until the track memory is full.
‘Wrap’ (default) – A track log will be continuously recorded by wrapping through
available memory and replacing the oldest track data with new data.
Interval defines the frequency with which the track plot is recorded. Three interval
settings are available:
‘Time’ – Records track log based on a user-defined time interval.
‘Resolution’ (default) – Records track log based upon a user-defined variance from
your course over ground. The resolution option is recommended for the most
efficient use of memory and TracBack performance. The distance value (entered in
the ‘Interval Value’ field) is the maximum left/right deviation allowed from the last
defined ground track before recording a new point.
‘Distance’ – Records track log based on a user-defined distance between points.
Interval Value defines the distance or time interval used to record the track log.
Clear Log allows you to clear the track log data currently stored in memory.
To delete the track log data, highlight ‘Delete Track’ and press ENTER.
TracBack converts the track log data in memory into an inverted route and begins
navigation along the route. See pages 64-65.
‘Fill’ will record track log data
until memory is full, then pro-
vide a ‘Track Memory Full’
message.
To utilize the TracBack fea-
ture, you should clear the
track log before leaving the
departure airport.
