About Logger

Logger is a FS9 and FSX module that provides file read and write capability for XML gauges. Logger allows hundreds of different number or string variables of any type (A:, E:, P:, G:, L:, or gps) to be written to or read from the hard disk. The module enables the user to write XML Flight Data Recorder gauges, save and load flight plans, save and load initial values for XML gauges that cannot otherwise be saved with Flight Sim's Save Flight, or record flights for subsequent playback as Google Earth Tracks and Tours.

The Logger module, help file, file read and write format guide, and example XML applications can be downloaded here. Additionally, several visually interesting Google Earth Tour and Track files as well as an Excel 2003 application that generates Google Earth .kml files are available.


You may use Logger in both commercial and non-commercial gauges. You cannot sell Logger or distribute it through any means other than this site.
