Safe Flight Guidelines

Flight Condition Requirements

Operational Requirements
Before using the product, please read the Disclaimer, “User Manual”and “Maintenance Manual”carefully.

Flight Restrictions
Please regularly update the flight restriction database online, and consult relevant local authorities before flying to ensure compliance with local laws and regulations. Before flying in a restricted flight zone, please apply for a waiver in advance.

Transportation Guidelines
The storage and transportation of smart batteries have certain safety requirements. Please strictly follow the contents of the “Battery Safe Operation Guidelines” for the best practices.

Firmware Upgrade
Before each use, it is recommended to update the firmware of the aircraft, intelligent flight battery and remote controller to the latest for a better experience. Please refer to the User Manual for firmware upgrade methods and precautions. If the upgrade fails, please restart the device and try again. If you still can’t solve the problem, please contact the official after-sales service of Autel Robotics.

Maintenance And Checks

It’s important to regularly carry out inspections and regular maintenance before operating the drone, as this can greatly improve product reliability, reduce potential safety hazards, and prolong drone service life.

Pre-flight Checks

Before each flight, the following items must be checked:

1. The batteries of the remote controller and the aircraft are fully charged, and the batteries must be installed in place without detaching;
2. Make sure that the propeller is an authentic Autel Robotics supplied propeller, the appearance is intact, it is installed firmly, the front and back propellers are both installed correctly, there is no foreign matter or debris in the motor and propeller, and there is no blockage in the manual rotation of the motor;
3. Make sure that the arms are fully unfolded, and ensure that the arms do not rebound and have a strong pre-tightening force;
4. Make sure that drone camera normal, and the lens is free of oil, occlusion, and fingerprints;
5. Make sure that the gimbal motor has been stabilized and the camera is facing the normal direction;
6. Make sure that the protective cover of the card slot and interface is securely closed, otherwise water may enter and affect the flight;
7. Make sure the antennas of the remote controller are unfolded and adjusted to an optimal angle;
8. Turn on the remote controller and the aircraft, check whether the indicator lights of the remote controller and the aircraft are normal, ensure that the remote controller is connected to the aircraft normally, and can correctly control both flight and gimbal;
9. Enter the flight interface of Autel Enterprise, check whether the flight status is”Safe to fly”, whether the obstacle avoidance function is turned on normally, and check whether any other parameters you may require are met in the settings to ensure flight safety;
10. If multiple aircrafts are operating at the same time, please pay attention to your flight area to avoid collisions and accidents.

Maintenance And Checks
It is recommended that users refer to the following standards to carry out regular inspections and maintenance to maintain the best condition of the aircraft and reduce potential safety hazards.

Flight Control System

1. The “Visual Positioning Mode” will appear after turning on the aircraft. Please observe the surrounding environment and place the aircraft in an open and unobstructed environment to search for satellites. If the number of searched satellites is more than 28, this is good and within the recommended range.
   

2. If the app prompts “Compass abnormal”, please stay away from interference areas and recalibrate.
   

3. If the app prompts “IMU is abnormal”please perform an IMNU calibration. If the problem cannot be solved, please contact Autel After-Sales service.

4. If the app prompts “Barometer abnormal”, please restart the aircraft and try again. If the abnormality continues, please contact Autel After-Sales service.

Battery Life
To prolong battery life, please avoid the following situations:

1. Avoid placing the battery in an environment with a temperature above 28℃ for a long time. The ideal storage temperature is 22-28℃.
2. Avoid storing fully-charged batteries for a long time. In order to protect the battery, BMS has a self-discharge function, lasting for 2-3 days. It is recommended to charge the battery to 60~75% before storage instead of activating the self-discharge function.
3. Avoid low battery storage. If the power is too low, BMS will enter ultra-low power protection. The battery itself has self-discharge, and if the battery is too low, it will damage the battery.
4. Avoid placing the battery in a high-humidity and high-salt environment for a long time, which may damage the interface and shell.
5. Do not use unauthorized chargers. The voltage and current output by unauthorized chargers cannot fully match the battery cells, which may cause damage to the batteries.
6. Avoid leaving the charger plugged in for a long time as this may damage the charger.

Battery Maintenance Conditions

In order to keep the aircraft battery healthy, maintenance is recommended if any of the following conditions are met

1. The battery has been cycled 50 times.
2. The battery has been inactive for 3 months.
3. The App prompts users that the battery needs maintenance.

Battery Inspection Process

1. The battery performs a standard charge and discharge operation.
2. Insert the battery into the aircraft and power on, check the battery information through the app, check whether the voltage difference between the battery cells is less than 0.1V, and whether the battery firmware is up to date.
3. Check whether the battery is bulged, leaked, or damaged.
4. Check the battery connector for dirt, damage or rust.

Charging And Discharging a Battery
Use the original charger, or the maintenance charging mode of the charging box, charge to 100% and let it stand for 24 hours. Then discharge to below 20% and let it stand for 1 hour.

1. Charge the battery to 100% and let it sit for 24 hours.
2. Insert the battery into the aircraft to fly, when the battery is less than 20%, land the aircraft. After landing, remove the battery.
3. Let the battery stand for 1 hour.
4. After completing the battery maintenance process, it can be charged and stored.

Battery Replacement Standards

1. There are obvious bulges, leakage, and damage on the battery surface.
2. Replacement is recommended after 300 cycles.
3. After 2 consecutive standard charging and discharging operations, if the abnormality of the battery still cannot be recovered, it is recommended to replace it.

Battery Disposal

1. Use an insulated bucket filled with 5% salt water and fully submerge in it for more than 48 hours until fully discharged.
2. After step 1, refer to the “Battery Safe Operation Guidelines” for correct recycling procedures to avoid any environmental pollution.

Precautions

1. Keep away from flammable and explosive items during charging.
2. Avoid using the battery in a humid environment to prevent the battery from short-circuiting.
3. Do not disassemble or puncture the battery.
4. Store the battery in a cool and dry place.
5. If the app prompts that the battery temperature is too high during flight, please return to home as soon as possible.

Update And Calibration
Please update the firmware of the aircraft and remote controller regularly, and perform regular calibrations.

Wearing Parts List
Replace damaged and consumed parts promptly to keep the aircraft in the best possible condition and reduce any potential safety hazards.

*Each power motor uses 2 blades CW or CCW.
**Replacement only required for deep maintenance.
