Track Log Settings (cont.)
Delete All allows you to clear all track logs, active and saved, from memory.
To delete all track logs from memory:
1. Select ‘Delete All’ from the Track Log Options and press ENTER.
2. Press ENTER again to confirm (or QUIT to cancel).
Setup Logging provides a setup screen to define how track log data will be recorded. The
Setup Logging Page provides options for ‘Record Mode’, ‘Interval’ and ‘Interval Value’.
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, wrapping through
available memory; replacing the oldest track data with new data.
Interval defines the frequency with which the track plot is recorded. Three
interval settings are available:
‘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.
‘Time’ – Records track log based on a user-defined time interval.
‘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.
Select ‘Save Active Log’ to save
the active log data for future
use. This process extracts the
most significant points along
the active route (up to 250)
and creates a ‘saved log’.
The ‘Setup Logging’ option
allows you to change the
criteria used to record the
active track log.
