FLIGHT RECORDER
When the Digifly instrument is recoding a flight, the record icon in shown at
the bottom of the screen.
If the recorder starts before the “UTC SYNC” had been obtained, it records a flight in
“2D” using the barometric altitude and the “R2d" icon is shown.
While recording in “2D” mode, if a valid GPS position had been obtained, the recorder
starts to record a new flight in “3D” mode and the record icon is at the
bottom of the screen.
In order to respect the FAI rules access to the “MAIN SETUP” menu on the Digifly
instrument is blocked when the flight recorder has been activated.

“AUT” Automatic start record mode.
-
“ALW” Always record mode
-
“OFF” No data recording.
8.1.1
AUTOMATIC START RECORD MODE
The default record mode is automatic start record mode, “AUT”, parameter (MAIN
SETUP \ n. 22 RECM).
In the automatic start record mode it is possible to change the parameters that initiates
the recording. You can adjust the change of height in meters (MAIN SETUP \ n. 23
R.DS) required for the instrument to automatically start recording a flight
In the automatic start record mode, the flight recorder will start on take off.
The take off is detected when there is a change of height (lift or sink) greater than 2
meters (MAIN SETUP \ n. 23 R.DS) over 4 seconds.
e.g. MAIN SETUP \ n. 23 R.DS = 2 means that a vertical speed (lift or sink) bigger
than 0,5 m/s for at least 4 consecutive seconds is required to recognize a take off (0,5
x 4 = 2).
In order to respect the FAI rules access to the setup menu on the Digifly instrument is
blocked when the flight recorder has been activated.
Once the recorder is activated, the flight recorder will only stop recording when the
instrument is turned off.
