When to Recalibrate
1. When compass data is abnormal, and the Aircraft Status Indicator is
blinking red and yellow.
2. When ying in a new location, or a location that is dierent from your last
ight.
3. When the mechanical structure of the N3 has changed, i.e. the mounting
position of the compass has changed.
4. When severe drifting occurs in ight, i.e. the N3 does not y in a straight line.
Flight Functions
Flight Modes
P-mode is preferred for most ying scenarios. Users can switch to Atti mode where and when
P-mode is unavailable. Be aware that some features are NOT available in Atti mode, and take
EXTRA caution when ying in Atti mode.
1. P-mode (Positioning): P-mode works best when the GNSS signal is strong. There are three
dierent states of P-mode, which will be automatically selected by the ight control system
depending on GNSS signal strength and Vision Positioning sensors:
a. P-GPS: GNSS and Vision Positioning are both available, and the aircraft is using GNSS for
positioning.
b. P-OPTI*: If GNSS is NOT available, the aircraft will use the Vision Positioning System to hover
accurately.
c. P-ATTI: When neither GNSS nor Vision Positioning is available, the aircraft is using only its
barometer for positioning, so only altitude is controlled.
2. Atti mode (Attitude): The GNSS and Vision Positioning System are NOT used for positioning.
The aircraft only uses its barometer to maintain altitude. If it is still receiving a GNSS signal, the
aircraft can automatically return home if the Remote Controller signal is lost and if the Home
Point has been recorded successfully.
3. S-mode (Sports): S-mode is identical to P-mode in terms of ight controller settings, except that
the handling gain values of the aircraft are adjusted in order to enhance the maneuverability of
the aircraft. The maximum ight speed of the aircraft is increased in this mode.
4. Manual mode: Only use it in emergency situations.
Using DJI GO (Lightbridge 2 is required):
Tap the Aircraft Status Indicator bar in the DJI GO app and select “Calibrate”, then follow the on-
screen instructions.
If the Aircraft Status Indicator blinks red and yellow after the calibration, move your
aircraft to a dierent location to carry out compass calibration.
Calibrate the compass before each ight. Launch DJI GO App, follow the on-screen
instructions to calibrate the compass.
