Strong GNSS Signal
Flight Restrictions Prompt in DJI Fly App
Max Altitude
Altitude of the aircraft cannot ex-
ceed the value set in DJI Fly.
Max ight altitude reached.
Max Distance
The straight-line distance from
the aircraft to the Home Point
cannot exceed the max ight dis-
tance set in DJI Fly.
Max ight distance reached.
Weak GNSS Signal
Flight Restrictions Prompt in DJI Fly App
Max Altitude
• Altitude is restricted to 30m
from the takeo point if light-
ing is sucient.
• Altitude is restricted to 3m
above the ground if lighting
is not sucient and the 3D in-
frared sensing system is func-
tioning.
• Altitude is restricted to 30m
from the takeo point if light-
ing is not sucient and the 3D
infrared sensing system is not
functioning.
Max ight altitude reached.
Max Distance No limit
• Each time the aircraft is powered on, the altitude limit will be automatically
removed as long as the GNSS signal becomes strong (GNSS signal strength ≥
2), and the limit will not take eect even if the GNSS signal becomes weak
afterwards.
• If the aircraft ies out of the set ight range due to inertia, you can still control
the aircraft but cannot y it any further away.
GEO Zones
The DJI GEO system designates safe ight locations, provides risk levels and safety
notices for individual ights, and oers information on restricted airspace. All restricted
ight areas are referred to as GEO Zones, which are further divided into Restricted
Zones, Authorization Zones, Warning Zones, Enhanced Warning Zones, and Altitude
