Version 2.45

July 6, 2022
Dynon users only: Some black box data recordings include a 17 second skip back in time. Also handles other incorrectly written time values in the file.
Experimental functionality, do not use. Export to X-Plane.

Version 2.44

May 25, 2022
Small bug fix for all analysis tools. These tools require a range greater than one second to be selected before the analysis tool is run. In some cases a one second range was allowed and would cause the analysis tool to fail.

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.

October 26, 2021
Small enhancement for users of Garmin devices. Recognizes and handles additional variants of 'RPM' CSV header.
Small enhancement for users of EFIS devices that do not record the altimeter setting (QNH). The 'IAS Calibration' tool formally required QNH, now it will fall back to use actual outside air pressure (if available).

Version 2.36

September 15, 2021
New feature: Experimental! Airports can be shown on the flight path.
Enhancement: MGL devices emit CSV files with slightly different schemas. This version will recognize all versions (to date).

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.
For Dynon users - Added fuel pressure column. Added option to select fuel pressure scale (PSI, Millibar, " Mercury) to the Options dialog.
Selecting ranges is now much faster.
If you select a range before exporting data to a CSV file (full or Savvy) only the data in the selected range is exported.
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 2.11

Released December 27, 2018
Fuel remaining now accounts for more than one fuel tank.
Added a setting to limit the number of flight data windows that can be open at a time. The default is 15. A large number of open windows consumed excessive memory.
Added a 'Help Tips' window which is displayed on startup.
Multiple flight data (*.FDXML) files can be opened from the Windows command line.
Bug fix. Fuel flow when displayed in liters/hour is now correct.
Bug fix for the older 'Enigma.rec' file format. Only affected users below the equator. Longitude and latitude are now correctly extracted from the data file.

Display voltage and current. Only available on Enigma and Extreme Mini. Current value is usually unreliable.
Display G-force reading on EFIS display when it is above 1.4 G.
Better handling of current row selection in the details 'spreadsheet' when using the playback control. Retains currently viewed columns.
Added new AHRS (Yaw) equipment enables in 'Options'. Previously selecting AHRS displayed pitch, bank and yaw columns. The saved AHRS (Yaw) value is meaningless on most EFIS systems. Default value is 'do not display'.
Added help tips to many of the 'Options'.
