Aircraft This section introduces the aircraft components, features and functions. © 2019 DJI All Rights Reserved.
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.
P4 Multispectral User Manual Aircraft Status Indicators The P4 Multispectral has Front LEDs and Aircraft Status Indicators. The positions of these LEDs are shown in the figure below: Front LEDs Aircraft Status Indicators 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 flight controller.
P4 Multispectral User Manual Return to Home (RTH) Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail. Description GNSS Home Point If a strong GNSS signal was acquired before takeoff, the Home Point is the location from which the aircraft launched.
P4 Multispectral User Manual Low Battery RTH The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect the safe return of the aircraft. The user can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds for these warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point. The Low Battery RTH will only be triggered once during the same flight.
P4 Multispectral User Manual When the Critical low battery level warning is triggered and the aircraft begins to land automatically, push the left stick upward to make the aircraft hover at its current altitude, giving you an opportunity to navigate to a more appropriate landing location. The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time. They are automatically adjusted according to the aircraft’s current location and status.
P4 Multispectral User Manual Aircraft cannot return to the Home Point when GNSS signal is weak ([ ] displays grey) or the module is unavailable. If you move the throttle stick after the aircraft rises above 65 feet (20 meters) but below the pre-set Failsafe RTH altitude, the aircraft will stop ascending and immediately return to the Home Point.
P4 Multispectral User Manual decreases to 0% will the aircraft land. Users retain control of aircraft flight orientation. 3. If Landing Protection is inactive, DJI GS Pro will display a landing prompt when the aircraft descends below 0.3 meters. Tap to confirm or pull down the control stick for 2 seconds to land when the environment is appropriate for landing.
P4 Multispectral User Manual In , set the capture mode, bands to be stored, and NDVI colormap. Capture mode: Select between single shot and timed shot. Bands to be stored: Choose which spectral band photos to save according to the application. When configuring visible imaging settings, users can select RGB, BLUE, GREEN, RED, RE, and NIR. When configuring multispectral imaging settings, users can select NDVI, BLUE, GREEN, RED, RE, and NIR. Only the photos of the selected bands will be saved.
P4 Multispectral User Manual Using with the DJI D-RTK 2 Mobile Station 1. Go to Mission Page in DJI GS Pro, tap the icon or RTK on top of the screen to go to the RTK settings menu, and then select D-RTK 2 as the RTK data source. Enable the aircraft RTK at the bottom of the menu to ensure the aircraft has access to RTK data. 2. Tap Link. The remote controller will start beeping. Then press the link button on the mobile station. 3. Tap Connect to establish connection with the server.
P4 Multispectral User Manual Detection Range The detection range of the Vision System and Infrared Sensing System are depicted as follow. Note that the aircraft cannot sense and avoid the obstacles that are not within the detection range. 0.7m 13.1cm 6.8m 7m 6.8m 7m 0.7m In P-mode, both the forward and the rear Vision Systems work if the speed is within 13mph (22kph). At higher speeds, only the vision system facing the direction of travel is active.
P4 Multispectral User Manual Follow the steps below to use Vision Positioning: 1. Turn on the aircraft. The aircraft status indicator will flash green two times, which indicates the Vision Positioning is ready. 2. Gently push the left stick up to lift off and the aircraft will hover in place. Assisted Braking from Obstacle Sensing Powered by the Obstacle Sensing, the aircraft will now be able to actively brake when obstacles are detected around the aircraft.
P4 Multispectral User Manual Flight Recorder Flight data is automatically recorded to the internal storage of the aircraft. To access this data, connect the aircraft to the PC through the Micro USB port and launch the DJI Assistant 2. Attaching and Detaching the Propellers Use only DJI approved propellers with your aircraft. The grey and black ring on the propeller indicate where they should be attached and in which direction whey should spin.

Flight This section describes safe flight practices and flight restrictions. 40 © 2019 DJI All Rights Reserved.
Flight Once the pre-flight preparation is complete, it is recommended to hone your flight skills through training and practice flying safely. The altitude limit is 1, 640 feet (500 meters). Avoid flying at any altitudes higher. It is important to understand basic flight guidelines for the safety of both you and those around you. Refer to the disclaimer and safety guidelines for more information. Flight Environment Requirements 1. Do not use the aircraft in severe weather conditions.
P4 Multispectral User Manual Warning Zones, Enhanced Warning Zones, Authorization Zones, Altitude Zones, and Restricted Zones. By default, GEO limits flights into or taking off within zones that may result in safety or security concerns. There is a GEO Zone Map, which contains comprehensive global GEO Zone information on the official DJI website: https://www.dji.com/flysafe. The GEO System is for advisory purposes only.
P4 Multispectral User Manual GEO Zone Flight Restrictions GEO Zone Description Takeoff: The aircraft’s motors cannot be started. Restricted Zone In-flight: When GNSS signal changes from weak to strong, DJI GS RTK starts a 20-second countdown. Once the countdown is over, the aircraft immediately lands in semi-automatic descent mode and turns off its motors after landing. In-flight: When the aircraft approaches the boundary of the Restricted Zone, it automatically decelerates and hovers.
