Aircraft

This chapter introduces various functional characteristics of the flight control system, visual system and intelligent battery in the aircraft.

Aircraft overview

The S400 aircraft mainly consists of a flight control system, a communication system, a visual system, an image processing system, a propulsion system and a battery system. This chapter introduces the functions of various components on the aircraft in detail.

Aircraft indicator light

The fuselage has a total of 4 front and rear arm indicator lights, and their positions are shown in the figure

Flight modes

The aircraft has the following flight modes, which can be switched manually through the remote controller and the GDU Flight II App. Details are as follows:

1. A mode (attitude)
The forward/backward obstacle sensing system, GNSS positioning and downward visual positioning system do not work; when the aircraft is off the navigation control, it will drift in the horizontal direction if the control stick is not pushed. It is required to use the control stick for real-time control.
2. P mode (standard)
If the GNSS signal is strong, the aircraft will be positioned through GNSS; if the GNSS signal is weak and the light conditions meet the needs of the intelligent visual positioning system, the intelligent visual positioning system will be used. If the GNSS signal and visual assistance positioning fail, the aircraft will automatically switch to the A mode to be controlled by a professional pilot.
3. F mode (sport)
The F mode is the enhanced mode under the P mode. The aircraft performance is enhanced, and the GPS and the downward vision positioning system is functioning. The aircraft’s control sensitivity value is prompted, and the flight response is quick. Please fly with caution. In this mode, the obstacle avoidance system is disabled, and the aircraft is unable to avoid obstacles automatically.
4. T mode (tripod)
The tripod mode restricts the aircraft’s maneuvering performance on the basis of P mode to make the aircraft shooting more stable.
5. V mode (vision)
The V mode refers to vision positioning mode. When the GNSS signal is weak, and aircraft altitude is lower than 9m, the system will automatically switch to the V mode. At this point, the aircraft’s maximum speed is restricted to 10m/s.

A mode (attitude) description

1. The A mode is a professional mode. Please do not switch to this mode in non-special conditions.
2. When the GNSS satellite signal is weak or the compass is interfered, and the vision positioning conditions are not met, the aircraft will enter the attitude mode in a passive manner.
3. The user can use the flight mode switch button on the remote controller to manually switch to the A mode. In this mode, the aircraft is likely to be interfered, and will drift in the horizontal direction. In addition, the visual system and some intelligent flight modes will not work. Hence, the aircraft cannot achieve fixed-point hovering and automatic braking on its own in this mode. The user needs to manually control the remote controller to hover the aircraft.
4. In this mode, it is much more difficult to control the aircraft. The user must be familiar with theaircraft behavior in this mode and be capable of operating the aircraft skillfully. The user should never fly the aircraft for a long distance to avoid the loss of determination of the aircraft attitude, which may cause a risk.
5. Once the aircraft enters the attitude mode in a negative manner, please land the aircraft as soon as possible to a safe place so as to avoid accidents. Meanwhile, avoid flying the aircraft in a narrow, semi-obstructed environment, or an environment with weak GNSS satellite signals to avoid entering the attitude mode in a passive manner, which may result in flight accidents.
6. When the aircraft triggers the vision mode, it can only be switched to the A mode. The other modes do not work.

F mode (sport) description

1. The user must note that, when flying the aircraft in the F mode (sport), the visual obstacle avoidance will not work. The aircraft will not actively brake. The user must take note of surrounding environments and operate the aircraft to avoid obstacles along the flight route.
2. The user must note that, when flying the aircraft in the F mode (sport), the aircraft’s flight speed is much increased than that in the P mode (standard). As such, the braking distance is greatly increased. When flying the aircraft in a windless environment, the user should reserve at least 50m braking distance to ensure flight safety.
3. The user can switch the P mode to the F mode for operation only after getting familiar with the aircraft characteristics and various flight modes.

Advanced networking mode

Introduction
The S400E supports an advanced networking mode which is suitable for controlling one aircraft using multiple remote control terminals and controlling several aircraft with one remote control terminal. Based on the equal weight design principle (in other words, the roles of multiple remote controllers are not distinguished), after pairing is finished, all remote controllers can establish flight control over the UAV. During operation, the pilot can assign flight control over the aircraft and view display control as required to allow the user to be more focused and efficient during operation. There are two types of control operation parameters: Flight control and view display control. When a remote controller has the flight control assigned to it, it can control the flight; when the remote controller has the view display control assigned to it, it can display the real-time view of the current aircraft.
Setting of the advanced networking mode
Before using the advanced networking mode, it is necessary to set the pairing of the remote controller and UAV respectively. Refer to the steps below: Build a network in networking mode: 1. Select one set of one-to-one-paired aircraft and remote controller (if the aircraft is not paired with
the remote controller, please pair it based on the one-to-one pairing mode); 2. Run the GDU Flight II App and click ” ” to enter the “Settings” interface and “Remote Controller
Settings” interface; 3. Enter the Level 2 page in Advanced Networking mode. In the “Networking Mode” drop-down list,
select the required Networking Mode (default: 1-to-1 mode); 4. After switching the Networking Mode interface, an empty gray node icon will Appear on the App
networking interface. Operate other nodes (remote controller or aircraft) to be added to the network; enter the pairing status and click the empty node on the App networking interface; a prompt stating “Paired sent successfully” will Appear on the App networking interface;
5. When the network receives the addition of an empty node, the original remote controller will be temporarily disconnected. When the empty node is added, check the topology icon of the Advanced Networking mode interface in the App. If it is green, this indicates that the network connection was successful and the device is online.

User Manual
Advanced networking description
1. Ensure that the first remote controller has been paired and connected to the aircraft. By default, the remote controller connected first has the control right over all devices (flight control right, view display control right), and the remote controller connected later can be repaired after the remote controller connected first assigns an unpaired node position.
2. When the remote controller has authorization to control devices (aircraft, gimbal camera, view display), it can control the device using the control stick, dial, shortcut key, UI icon, and other functions. The usage method is the same as using the remote controller alone.
3. The user can click to select the aircraft to be controlled and obtain the flight control permissions and view display control right over this aircraft. They can press and hold the aircraft to be controlled to only obtain the flight control right. Only a remote controller with flight control right can enable the function to return or cancel the return.
4. By default, the Advanced Network icon on the Flight Control interface is in the Networking Mode (namely, one remote controller controls one aircraft). In addition, this icon is not displayed. This icon is displayed in the non-default Networking mode to obtain the number of specified aircraft in the current Networking mode (including online, offline, and unpaired statuses).
5. In multi-control operation scenarios, when one remote controller loses communication with the aircraft, a message notification will be triggered. The user can manually select whether to take over the flight control rights. When the online remote controller opts not to take over the flight control rights, the aircraft will execute the lost communication solution. When the online remote controller fails to make a decision within specified time, the aircraft will also execute the lost communication solution.
6. During flight operation, when a remote controller that has lost communication is connected to the aircraft again, it is defaulted to have control over all devices.
7. All remote controllers can set the operation of devices related to flight, including flight control software, sensing system, battery, and video transmission settings provided that the flight control permission has been granted.
8. When no operation mission is being executed, the node can be removed by pressing and holding the paired node on the “Networking Mode Settings” page. After the node is removed, the node position will be adjusted to be unpaired, and the device’s networking status will be reset. To pair the device again, a paired remote controller is required to specify an unpaired node position and connect the node to the network again after pairing.
9. When no operation mission is being executed, the networking mode can be set on the “Networking Mode Settings” page. When the number of devices in setting mode decreases, and this type of node has been connected to all corresponding device, it is required to manually remove excessive node devices to finish the mode switch; when the number of devices in setting mode increases, the total number of devices is restricted to 2-3, including the aircraft and remote controller.
10. The node type, node number, and node sequence in the Networking Mode cannot be changed. 11. When all nodes in the Networking Mode are paired, the device cannot be connected before
specifying an unpaired node; however, the remote controller in the first node can be replaced for connecting through the default remote controller pairing mode. This is Applicable to initial pairing, a lost remote controller, and other scenarios. Description of video transmission The S400E aircraft adopts the professional video transmission technology developed by GDU that supports dual-channel 1080p video transmission and the operation of a single remote controller or multiple remote controllers
· The video transmission resolution is limited by the output capacity of different payloads. Please refer to the actual display.

This chapter introduces flight precautions, flight restricted areas and aircraft precautions

Flight
Before a normal flight, please ask the professionals to conduct flight training and guidance training. During flight, please choose an appropriate flight environment to ensure the flight safety. Before a flight, be sure to read the Disclaimer and Safety Guidelines to learn safety precautions.
Flight restriction functions
No-fly zone
The no-fly zone is based on the 12 coordinate points of the restriction surface and tolerance buffer zone of civil airport obstacles published by the Civil Aviation Administration. The aircraft cannot take off in a no-fly zone. When approaching from an external area to the buffer zone at the no-fly zone boundary, the aircraft will automatically decelerate and hover. When the aircraft enters a no-fly zone due to special reasons, the forced landing function will be triggered. At this point, the aircraft will be forced to land. During descending, the aircraft can move in the horizontal direction, but the control stick cannot be pushed upwards. The altitude limit zone is a rectangle area of roughly 20km wide and 40km long by extending the midpoints at both ends of the runway outward for 20km, and extending for 10km along the two sides of the runway (the non-intersect part with the no-fly zone). In the altitude limit zone, the aircraft’s flight altitude is restricted to 120m.

User Manual
Buffer zone
The buffer zone is the zone by extending the no-fly zone outwards by 120m. 1. When the aircraft approaches to the buffer zone, the App starts to prompt the user that the aircraft
is approaching the no-fly zone. Please note the flight direction. 2. When the aircraft enters the buffer zone, the same will start automatic braking until hovering. Within
the buffer zone, pushing the control stick towards the no-fly zone direction will not work. However, the control stick can be pushed in other directions within the altitude limit range.
Mission flight
1. When the mission flight route is within the no-fly zone, the aircraft cannot take off and cannot execute the mission.
2. In the restricted zone, when the point height of the flight route mission does not exceed the 120m altitude limit, the mission can be executed normally; and when the set altitude is higher than the 120 m altitude limit, the aircraft will hover at 120m.
3. When the waypoint A in the flight route is within the restricted zone, and waypoint B is outside the restricted zone and above the altitude limit, the aircraft will first fly to the altitude limit A1 and move horizontally out of the restricted zone to A2 position. Then, it will adjust the altitude to B point altitude and reach the A3 position to execute the mission. As shown in the figure below:
