Aircraft
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 Inspire:
P-GPS: GPS and Vision Positioning both are available, and the aircraft is using GPS for position.
P-OPTI: Vision Positioning is available but the GPS signal is not. Aircraft is using only Vision
Positioning for hovering.
P-ATTI: Neither GPS or Vision Positioning available, aircraft is using only its barometer for
position, so only altitude is controlled.
A mode (Attitude): The GPS and Vision Positioning System is not used for holding position. The
aircraft only uses its barometer to maintain altitude. If it is still receiving a GPS signal, the aircraft can
automatically return home if the Remote Controller signal is lost and if the Home Point has been
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.
Vision Positioning is a positioning system that uses ultrasonic and image data to help the
aircraft identify its current position.
Use the Flight Controller mode switch to change the flight mode of the aircraft.
The Inspire 1 comes with the Front LED, Rear LED and Aircraft Status Indicator. The positions of these
LEDs are shown in the figure below:
The Front LED (solid red) and Rear LED (solid green) show the orientation of the aircraft.
