Flight Status Indicator

The Phantom 3 4K has Front LEDs and Aircraft Status Indicators. The positions of these LEDs are shown

in the gure below:

The Front LEDs show the orientation of the aircraft. The Front LEDs glow solid red when the aircraft is

turned on to indicate the front (or nose) of the aircraft. The Aircraft Status Indicators communicate the

system status of the ight controller. Refer to the table below for more information about the Aircraft Status

Indicators:

Flight Controller

The Phantom 3 4K’s ight controller features several important upgrades, including a new ight mode.

Safety modes include Failsafe and Return-to-Home. These features ensure the safe return of your aircraft

if the control signal is lost. The ight controller can also save critical ight data from each ight to the on-

board storage device. The new ight controller also provides increased stability and a new air braking

feature.

Flight Mode

Three ight modes are available. The details of each ight mode are found below:

P-mode (Positioning) : P-mode works best when GPS signal is strong. There are three different states of

P-mode, which will be automatically selected by the Phantom 3 4K depending on signal strength of GPS

and Vision Positioning sensors :

P-GPS: GPS and Vision Positioning both are available. The aircraft is using GPS for positioning.

P-OPTI: Vision Positioning is available but the GPS signal strength is not sufcient. The aircraft is

using only the Vision Positioning System for positioning.

P-ATTI: Neither GPS nor Vision Positioning is available. The aircraft is using only its barometer for

positioning, so only altitude can be stabilized.

A-mode (Attitude): GPS and Vision Positioning System are not used for stabilization. The aircraft only uses

its barometer. The aircraft can still automatically return to the home point if the control signal is lost and

the Home Point was recorded successfully.

F-mode (Function): Intelligent Orientation Control (IOC) is activated in this mode. For more information

about IOC, refer to the IOC section in the Appendix.

Use the Flight Controller mode switch to change the ight mode of the aircraft, refer to the “Flight

Mode Switch” on Page 26 for more information.
