automatically switch between three flight modes.
Table 1-9 Flight Modes
Flight Modes Description
GNSS Mode
GNSS mode is activated when the aircraft detects an appropriate
GNSS signal. In GNSS mode, if the visual obstacle avoidance system is
turned on, the visual system will provide auxiliary information to
more accurately locate and avoid obstacles, provide stable and
smooth flight control, and support return-to-home and failsafe
protection and other safety functions.
Visual Positioning
Mode
When the aircraft is in the visual positioning mode, and the GNSS
signal detected is not strong enough to activate GNSS mode, and it
meets certain environmental and altitude requirements (ensure that
the surrounding environment is well lit, the ground texture is clear,
and the height of the aircraft must be within the perception range of
the visual system), the visual positioning mode will be activated.
ATTI Mode
When there is no GNSS signal and the environment and height cannot
meet the vision system, that is, when there is no GNSS signal and
visual positioning failure at the same time, the ATTI mode will be
activated. In this mode, the obstacle avoidance system is disabled,
and the aircraft only controls the altitude through the barometer.
If you have not fully mastered the flight control of the aircraft and the aircraft is in ATTI
mode, please do not take off rashly as this may lead to accidents or loss of your aircraft.
1.3.2 Speed Modes
The user can set the default speed mode in the "Flight Control Settings" interface, or switch
the flight speed modes in the "Status Notification Bar". For details, see "4.3.1 Flight Control
Parameter Settings" and "4.4 Status Notification Bar".
