Aircraft

Profile

The P4 Multispectral aircraft includes a flight controller, a communication system, a positioning
system, a propulsion system and an Intelligent Flight Battery. This section describes the functions
of these components.

Flight Modes

The P4 Multispectral provides the following flight modes. Use the flight mode switch on the
remote controller to switch between different flight modes. The P and S positions on the remote
controller are for P-mode, and the A position is for A-mode.
P-mode (Positioning): P-mode works best when the GNSS signal is strong. The aircraft utilizes
the GNSS / RTK module and Vision System to automatically stabilize itself and navigate between
obstacles. When the GNSS signal is strong, the aircraft uses GNSS for positioning. When RTK
module is enabled and the differential data transmission is good, it provides centimeter-level
positioning. When the GNSS signal is weak and the lighting conditions are sufficient, the aircraft
uses Vision System for positioning. When the forward obstacle sensing is enabled and lighting
conditions are sufficient, the maximum flight attitude angle is 25° with a maximum flight speed of
31 mph (50 kph). When forward obstacle sensing is disabled, the maximum flight attitude angle is
35° and the maximum flight speed is 36 mph (58 kph).
A-mode (Attitude): GNSS is not used for positioning and the aircraft can only maintain altitude
using the barometer.
Attitude Mode Warning
The aircraft will enter A-mode in the following two instances:
Passive: When there is weak GNSS signal or when the compass experiences interfer-
ence where the Vision System is unavailable.
Active: Users toggle the flight mode switch to A-mode.
In A-mode, the Vision System and some advanced features are disabled. Therefore,
the aircraft cannot position or auto-brake in this mode and is easily affected by its
surroundings, which may result in horizontal shifting. Use the remote controller to
position the aircraft.
Maneuvering the aircraft in A-mode can be difficult. Before switching the aircraft into
A-mode, make sure you are comfortable flying in this mode. DO NOT fly the aircraft too
far away as you might lose control and cause a potential hazard. Avoid flying in confined
spaces or in areas where the GNSS signal is weak. Otherwise, the aircraft will enter A-mode,
leading to potential flight risks. Land the aircraft in a safe place as soon as possible.
