Flight Controller
The Phantom 4’s controller is based on DJI flight controller with several enhancements such as new flight mode
and new safe mode. Three safe modes are available: Failsafe, Return Home and Dynamic Home Point. These
features ensure the safe return of your aircraft if the control signal is lost. A flight recorder stores crucial
flight data for each flight.
Flight Mode
Three flight modes are available. The details of each flight mode are found in the section 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 4 depending on GPS signal strength and Vision
Positioning sensors:
P-GPS: GPS and Vision Positioning both are available, and the aircraft is using GPS for positioning.
P-OPTI: Vision Positioning is available but the GPS signal is not. Aircraft is using only Vision Position-
ing for hovering
P-ATTI: Neither GPS or Vision Positioning available, aircraft is using only its barometer for positioning, so only
altitude is controlled.
A mode (Attitude): GPS and Vision Positioning System is not used for stabilization. The aircraft only uses
its barometer to stabilize. The aircraft can automatically return home if remote control signal is lost if the
Home Point is recorded successfully.
F mode (Function): Intelligent Orientation Control (IOC) is activated in this mode. For more information about
IOC, refer to the IOC in Appendix.
Use the Flight Controller mode switch to change the flight mode of the aircraft, refer to the “Flight Mode
Switch” on P24 for more information.
