N/A N/A N/A
When Critical battery level warning is triggered and the aircraft begins to land automatically,
you may push the left stick upward to make the aircraft hover at its current altitude, giving you
an opportunity to navigate to a more appropriate landing location.
The colored zones and markers on the battery level indicator bar reflect the estimated
remaining ight time. They are automatically adjusted according to the aircraft’s current location
and status.
Precision Landing
The Phantom 4 automatically scans and attempts to match the terrain features underneath during Return
to Home. When current terrain matches home point terrain, the Phantom 4 will start landing immediately
to achieve precision landing. The DJI GO 4 app will show a terrain feature mismatch prompt if matching
fails.
Precision Landing performance is subject to the following conditions:
a) Home point is recorded upon take off, and cannot not be refreshed during ight.
b) Aircraft must take off vertically. Take off altitude must be greater than 7 meters.
c) Home point terrain features remain largely unchanged.
d) Home point terrain with no distinctive features will affect the performance.
e) Lighting conditions cannot be too light nor too dark.
The following actions are available during landing:
a) Pull throttle down to accelerate landing.
b) Moving the control sticks in any other direction will stop Precision Landing. The Phantom 4
will descend vertically and Landing Protection will remain active.
