4.5. Flight modes
ELIOS 3 offers multiple flight modes depending on the payload configuration. It is essential that the pilot
understands the differences between the several modes and when to use them.
4.5.1. Sensor Stabilized control—ASSIST (default)
Optical sensor limitation: Presence of dust, direct sunlight, or featureless surfaces.
LiDAR limitation: Presence of dust, cylindrical or general symmetric environments, as there are no
geometrical features to help the sensor understand where you are along the axis of symmetry.
By default, ELIOS 3 uses its optical sensors coupled with its IMU (accelerometer and gyroscope) to increase its
stability close to surfaces or objects.
ASSIST mode ensures that you never exceed the maximum collision speed of the drone and is thus the safest
mode to fly in.
4.5.2. Attitude control—ATTI
Limitation : Unstable static pressure
In an environment where ASSIST mode does not function due to the limitations of all the available sensors,
ELIOS 3 will fall back to relying solely on its IMU and barometer for stability. While in attitude control mode
(ATTI), the altitude of the aircraft is automatically handled by the barometer. The drone will
not automatically
remain stationary in this mode and will constantly drift due to local wind and turbulence effects.
The flight control system continuously monitors the quality of the sensor data, and automatically switches to
ATTI when necessary. Although the drone should always function with reliable stability it is ultimately the
pilot's duty to assess whether the stabilization is functioning sufficiently in a given environment, and to be
ready to manually switch to ATTI mode if needed.
Please note that in this mode the drone may exceed the maximum safe collision speed, ensuring you avoid
high-speed collisions, as they might result in loss of the aircraft.
4.5.3. Manual thrust control—MAN
Both the ASSIST and ATTI flight modes rely partially on barometric pressure data to maintain a constant
altitude. Strong local wind, ventilation, or natural drafts may disturb the static pressure measured by the
barometer of the drone, leading to erratic flight behavior. The pilot can disable the barometer by switching to
Manual Thrust Control (MAN). Switching on Manual thrust mode will automatically switch on ATTI mode.
In the MAN flight mode, the altitude joystick directly controls the motor RPM, leading to virtually unlimited
climb and descent speeds which can easily lead to extremely hard collisions. Please note that in this mode the
