FLIGHT MODES
NOT CONNECTED FLIGHT MODE
Not Connected Flight mode is set when there is no aircraft bound to DataPilot™. A valid RC connection is
required for a flight mode to be present.
AUTO-POSITION FLIGHT MODE
Auto-Position Flight mode is automatically set when the aircraft is flying autonomously but has no
commands to execute. In this case, the H520 will hold its current position and hover in place.
MANUAL FLIGHT MODE
Manual Flight mode is selected either by flipping switch S4 to the top position or tapping the flight mode
soft key on the DataPilot™ home screen. Manual Flight mode disables all GPS on the H520, however
altitude is maintained using barometric sensors. Manual Flight mode enables the Pilot to fly in GPS-denied
environments such as indoors or under/around obstacles. Manual Flight mode will not prevent drifting
during maneuvers, hence the Pilot is required to apply opposite stick input to stop drift. Manual flight Mode
is indicated on the H520 by the yellow LEDs on the two rear motor arms.
ANGLE FLIGHT MODE
Angle Flight mode is selected by centering switch S4 or by tapping the flight mode soft key on the
DataPilot™ home screen. Angle Flight mode incorporates GPS, barometric and other sensors to maintain
stable position in-flight. Angle Flight mode is indicated on the H520 by the purple LEDs on the two rear
motor arms.
MISSION FLIGHT MODE
Mission Flight mode is the mission execution mode. After uploading and starting a mission, the H520 will
automatically be set to Mission flight mode. Mission Flight mode is indicated on the H520 by the blue LEDs
on the two rear motor arms.
RETURN TO LAUNCH (RTL) FLIGHT MODE
Return to Launch flight mode is selected by placing switch S4 in the full down position or by tapping the RTL
soft key on the ST16S Fly panel. Return to Launch Flight mode is an automatic execution of the H520 to
return to the launch point. During RTL, the Pilot has limited control over the H520. RTL Flight mode is
indicated by flashing blue LEDs on the two rear motor arms.
LOW BATTERY FLIGHT MODE
During low battery flight mode, the H520 will attempt to RTL. In some cases, the H520 might be too far
from the launch site to return. During low battery flight mode, the Pilot has limited lateral control and no
vertical control of the H520. Low battery flight mode is indicated by flashing red LEDs on the two rear
motor arms.
