Flight Condition Requirements
Weather Conditions and Surrounding Environment
The aircraft is designed to operate in good to moderate weather
conditions. To avoid collision, serious injury, property damage or
imposing health hazards, observe the following rules:
1. DO NOT use the aircraft in adverse weather conditions such
as winds exceeding 6 m/s, heavy rain (precipitation rate
exceeding 25 mm (0.98 in) in 12 hours), snow, or fog.
2. To prevent health hazards to nearby people and to ensure
effective spray, operate the aircraft to spray in wind speeds below
6 m/s. It is recommended to operate the aircraft in wind speeds
below 3 m/s when using herbicide, fungicides, or insecticides
that are easy to drift and that pose phytotoxic risks.
3. Keep the aircraft at least 10 m (30 ft) away from obstacles, people,
animals, buildings, public infrastructure, and bodies of water when
in flight. As the aircraft's altitude increases, keep an even further
distance away from the aforementioned objects or obstacles.
4. DO NOT fly over 4.5 km (14,763 ft) above sea level.
5. The DJI Agras app will intelligently recommend the payload weight
of the tank according to the current status and surroundings of the
aircraft. When adding material to the tank, the max weight should
not exceed the recommended value. Otherwise, the flight safety
may be affected.
6. DO NOT operate any part of the aircraft indoors.
1. Aircraft and battery performance is subject to environmental factors
such as air density and temperature.
a. Be careful when flying 2 km (6,560 ft) or more above sea level as
battery and aircraft performance may be reduced.
2. DO NOT use the aircraft near accidents, fire, explosions, floods,
tsunamis, avalanches, landslides, earthquakes, dust, or sandstorms.
3. In low temperature environments (between 0° and 10° C (32° and
50° F)), make sure that the flight battery is fully charged and be
sure to reduce the payload of the aircraft. Otherwise, it will affect
the flight safety or a takeoff limit will occur.
Interference with Flight Controller and
Communications
1. Fly in open areas. Tall buildings, steel structures, mountains, rocks, or
forests may affect the accuracy of the on-board compass and block
both GNSS and remote control signals.
2. Avoid using wireless devices that use the same frequency bands as
the remote controller.
3. When using with multiple aircrafts, including T50, T25, and other
aircraft, make sure that the distance between each aircraft is more
than 10 m to avoid interference.
4. The sensitivity of the radar module may be reduced when operating
several aircraft within a short distance. Operate with caution.
5. Be alert when flying near areas with magnetic or radio interference.
These include, but are not limited to, high voltage lines, large scale
power transmission stations or mobile base stations, and broadcasting
towers. Failing to do so may compromise the transmission quality
of this product or cause transmission errors which may affect flight
orientation and location accuracy. The aircraft may behave abnormally
or go out of control in areas with too much interference.
6. If the RTK dongle is used for field planning, the module should be
disconnected from the remote controller after planning is completed.
Otherwise, it will affect the communication performance of the
remote controller.
Operating the Aircraft Responsibly
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
8
1. Make sure you are not under the influence of alcohol, drugs, or
anesthesia, or suffering from dizziness, fatigue, nausea, or any
other conditions, whether physical or mental, that could impair
your ability to operate the aircraft safely.
2. DO NOT stop the motors mid-flight unless in an emergency
situation where doing so will reduce the risk of damage or injury.
3. Upon landing, power off the aircraft, and then power off the
remote controller.
4. DO NOT drop, launch, fire, or otherwise project any dangerous
payloads on or at any buildings, persons, or animals, or which
could cause personal injury or property damage.
1. Make sure you have been sufficiently trained and have contingency
plans for emergency situations or for when accidents occur.
2. Make sure you have a flight plan and DO NOT fly the aircraft
recklessly.
3. DO NOT use this product for any illegal or inappropriate purpose
such as spying, military operations, or unauthorized investigations.
4. DO NOT use this product to defame, abuse, harass, stalk, threaten, or
otherwise violate the legal rights of others, such as the right of privacy
and publicity.
5. DO NOT trespass onto private property of others.
Flight Modes, Operation Modes, Functions,
and Warnings
Flight Modes
The aircraft will fly in N-mode (Normal) by default.
The aircraft will revert to A-mode when the GNSS signal is weak or
when the compass experiences interference. The flight speed in
A-mode depends on its surroundings such as the wind speed.
In A-mode, the aircraft cannot position itself 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. 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.
Operation Modes
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. Make sure that you fully understand the aircraft's behavior under
each operation mode before use.
2. Stay clear of obstacles near the operation route. Maintain line of
sight to the aircraft and observe its status at all times.
3. Only operate in Route or Orchard Operation mode when receiving
a strong GNSS signal.
Failsafe and Return to Home (RTH)
1. RTH will not work if there is a weak or no GNSS signal.
2. Tall buildings may adversely affect RTH. Therefore, it is important
to set an appropriate failsafe altitude before each flight. Adjust the
aircraft location, altitude, and speed while returning home to avoid
obstacles when there is a strong remote controller signal.
3. Make sure to fly the aircraft within the transmission range of the
remote controller.
4. Only use RTH in emergency cases, as they may be affected by the
weather, the environment, or any nearby magnetic fields.
5. The aircraft decelerates and brakes and hovers if there is an obstacle
within 20 m of the aircraft. The aircraft exits RTH and waits for further
commands.
