4 – Flying ELIOS 2
ELIOS 2 USER MANUAL
Page 29 of 106
Limitation: The surface can’t be too thin or be a reflective surface.
Thanks to its multiple vision and distance sensors, ELIOS 2 is able to fix its distance with regard to a surface.
The distance is set from the Front distance sensor. Hence, the distance always represents the horizontal
distance between the front of the aircraft and the surface independently from the camera orientation.
Flight data logging and video recording
Data logging
LOG SD CARD
As soon as the battery is plugged in, ELIOS 2 is turned on it starts to record data onto the LOG SD card.
The LOG files can be read with the Flyability Inspector software in order to access the Thermal Camera
footage and flight parameters such as altitude, heading, and POIs. The drone can not fly without a LOG
SD card.
AV SD CARD
The Avionics LOG files contain the flight information such as sensor values, internal aircraft states, and
even controller inputs from the pilot. It is the black box of the drone. This data can be downloaded and
sent to Flyability engineers to analyze malfunctions should they occur, but they are not readable for
the end user. Old files are automatically overwritten after 20 flights. The drone can not fly without an
AV SD card.
Video recording
The video recording starts as soon as Elios is armed and stops when Elios is disarmed, provided that the CAM
SD card is inserted with enough free space. The video as well as still images are saved onto the CAM SD card.
Tablet Backup Recording
The video stream received by the tablet can be saved to create a low-quality backup of the flight video as well
as some telemetry data, preventing a complete loss of data in case of an accident.
COCKPIT BACKUP RECORDER
This feature can be turned on in the settings menu of the Cockpit App. It records a video file with the
received video stream and creates a subtitle file (.srt) with the telemetry data.
A LOSS OF POWER (DUE TO A CRASH OR BATTERY DISCONNECTION)
WHILE ELIOS IS FLYING MAY CAUSE A LOSS OF THE VIDEO FILE BEING
RECORDED ON THE CAMERA SD CARD.
