You can also jump to the point of interest in the log using the slider and control the speed of the playback with the predefined Speed buttons.
While the log is replaying, the HUD will move and the vehicles location on the map will update as it did during the flight. Individual data values can be seen through the Status tab and you can even display them in a graph by clicking on the “Tuning” checkbox under the map and then double clicking on the data legend to bring up a box from which you can choose exactly which data fields are graphed as shown below. This will show the recorded data changing as the flight progresses.
