Version 2.43
May 17, 2022
| Dynon users only: Some black box data recordings include a 17 second skip back in time. The skip back is due to the GPS clock changing during the flight. This version shifts the times so that all are unique and correct. |
Version 2.42
May 8, 2022
| New feature: added 'Fuel Economy' analysis. Requires fuel flow and GPS data. |
| 'Takeoff Performance' analysis will use GPS groundspeed if IAS is not available. |

| New: Feature added to the 'Climb and Glide Rate Analysis tool'. You can now permanently delete data points. |
| Minor bug fix: Incorrect bank and pitch direction labels in the data grid have been fixed. |
| Minor bug fix: User could click on a graph or the flight path while the flight playback feature was active. This would move the cursor momentarily but it would immediately pop back to the running playback position. Now clicking while playback is active will have no effect. To set the cursor stop playback first. |
Version 2.24
August 18, 2020
| Large files (with flights longer than about 1-1/2 hours) load faster and use less memory. |
| For Dynon users - Added % power graph and column. |

| Some columns that do not contain any data will no longer be included in the data grid. For example: AGL, slip. |
| For Dynon users - Fixed the 'Local Time' for data extracted from Dynon files. The displayed value (first column) will be the local time of the flight event. The next column shows the time since the flight started. (Note: You can click on the 'Time (Local)' column header and the data will switch to 'Time (Zulu)'. Clicking again switches it back.) |
| 'Analyze' --> 'Statistics'. You can now select the number of decimal places to display. Useful for values like fuel flow. |
| Fixed the fuel usage box in the fuel flow graph. (Note: To change the fuel used units you'll need to change the fuel volume units on the data configuration.) |
Version 2.23
July 3, 2020
| Bug fix for users of versions 2.21 and 2.22. When changing options the application will save changes then terminate when the OK button is pressed. |
Version 2.22
June 7, 2020
