FAQ
What is ActiveTrack?
ActiveTrack allows an aircraft to track a moving subject without a separate GPS tracker. Simply tap on the
mobile device screen inside the DJI GO app to select the subject to be tracked. The aircraft will lock on the
subject and start tracking it automatically from a safe distance.
What is TapFly?
TapFly means you can y in any direction with a tap of the nger, without a remote controller. With Obstacle
Avoidance turned on, the aircraft will automatically avoid obstacles, slow down or hover when required,
provided that the scene is bright enough ( < 300 lux) or too bright ( > 10,000 lux).
What is the Phantom 4 Obstacle Sensing System?
The Phantom 4 is equipped with an Obstacle Sensing System that constantly scans for obstacles in front of
it, allowing it to avoid collisions by going around, over or hovering.
Why does the Phantom 4 have a magnesium core?
The revolutionary magnesium core embedded into the aircraft greatly increases rigidity, minimizing
unwanted vibrations. This ensures the precision and performance of the inertial measurement unit (IMU).
The weight of the aircraft is also reduced through this magnesium core.
What changes were made to the Phantom 4 remote?
The Phantom 4 introduces a Sport mode, accessible through a new trio of modes, P, S and A.
P (Position) mode is the standard mode, giving access to normal ight as well as Intelligent Flight Modes,
ActiveTrack and TapFly.
S (Sport) Mode unlocks maximum ight speeds of up to 44mph (72kmh).
A (Attitude) Mode remains the same and removes satellite stabilization in ight. It allows the Phantom to
move more smoothly and naturally.
The ‘Playback’ button on the top right of the remote controller has been changed into a ‘Pause’ button that
lets you put the Phantom into hover during any Intelligent Flight Mode, ActiveTrack or TapFly with a tap.
What improvements have been made to the Phantom 4 Vision Positioning Unit?
The Vision Positioning System now uses four sensors to increase hovering accuracy and reliability, creating
a more controlled ying experience. Its sonar system has been improved and now functions from up to 10
meters off the ground. In ideal situations, these combine to give the Phantom 4 Vision Positioning System a
vertical hover accuracy of +/- 0.1 m and a horizontal hover accuracy of +/- 0.3 m.
What is the effective range of the Obstacle Sensing System on Phantom 4?
The effective range of the Obstacle Sensing System is 0.7 to 15 meters. Although the DJI GO app will indicate
when there are obstacles present, pilots should always be paying attention to the aircraft during ight.
