4.13 Data Recording Setup
The XTreme has the ability to act as a black box recorder recording flight data directly onto an inserted SD card for later
playback and investigation using the MGL Avionics Enigma Black Box viewer program. See the Enigma Black box viewer
documents for further information. The Black box viewer can also convert the data into other file formats such as:
• KML: Keyhole Markup Language / Google Earth
• CSV: Comma-Separated Variable
• IGC: FAI Gliding commission
The XTreme automatically records the following flight data when the data recording is enabled:
• Data and Time
• Altitude
• Barometer
• Airspeed
• TAS
• VSI
• Glide/climb ratio
• Volts
• OAT
Other fields such as engine data, attitude, and GPS data are user selectable. The XTreme records all available data for
each selected category once per second WHEN A VALID FLIGHT IS DETECTED (AUTOMATIC OR MANUAL FLIGHT
DETECT MODE).
CREATE RECORDING FILE ON SD CARD:
Selecting this menu option will create a file on the SD card (If inserted and not write protected) called enigma.rec with a
fixed file size of 10MB. The reason behind the fixed file size of the recording file has to do with limited write cycles of the
SD card and the instability of the MS-DOS file system. With a fixed file size, the EFIS never has to write to either the
directory structure or FAT tables of the SD card eliminating wear of the card or possible data corruption. Once the
recording file has been filled, the recording continues at the start of the file again, overwriting the oldest data in the file.
The file size is large enough to record 5-20 hours of data depending on what data is recoded.
DATA RECORDING ON:
Selecting “ON” will enable the data recording functionality.
RECORD ENGINE DATA:
Select “ON” to include the engine data in the recoded flight data.
RECORD ATTITUDE DATA:
Select “ON” to include the attitude data in the recorded flight data.
