Flight Modes
The aircraft supports N mode (Normal), S mode (Sport), and F mode (Function)
and flies in N mode by default. Flight modes can be switched using the remote
controller B after gain aircraft control. Normal Mode In N mode, the aircraft
uses GNSS to locate and stabilize itself when the GNSS signal is strong. When
the GNSS is weak, but the lighting and other environmental conditions are
sufficient, it uses the vision systems. When the Forward and Backward Vision
Systems are enabled and lighting conditions are sufficient, the maximum tilt
angle is 25 ° , and the maximum forward flight speed is 36 mph (54 kph).

DJI Dock 2 User Manual
Sport Mode In Sport Mode, the aircraft uses GNSS for positioning and the
aircraft is more responsive to control stick movements. Note that obstacle
sensing is disabled and the maximum flight speed is 21 m/s in Sport Mode.
Function Mode Function mode can be set to T-mode (Tripod mode) or A-mode
(Attitude mode) in DJI Pilot 2. In Tripod mode, the aircraft is more stable
during shooting Attitude mode must be used with caution. The aircraft
automatically changes to ATTI mode when the vision systems are unavailable or
disabled and when the GNSS signal is weak or the compass experiences
interference. In ATTI mode, the aircraft may be more easily affected by its
surroundings. Environmental factors such as wind can result in horizontal
shifting, which may present hazards, especially when flying in confined
spaces.
· DO NOT switch from Normal mode to other modes unless you are sufficiently
familiar with the aircraft behavior under each flight mode. You must turn on
Multiple Flight Modes in DJI Pilot 2 before switching from Normal mode to
other modes.
· The vision systems are disabled in Sport mode, which means the aircraft
cannot sense obstacles on its route automatically. The user must stay alert to
the surrounding environment and control the aircraft to avoid obstacles.
· The maximum speed and braking distance of the aircraft significantly
increase in Sport mode. A minimum braking distance of 30 m is required in
windless conditions.
· A minimum braking distance of 10 m is required in windless conditions while
the aircraft is ascending and descending in Sport mode or Normal mode.
· The responsiveness of the aircraft significantly increases in Sport mode,
which means a small control stick movement on the remote controller translates
into the aircraft moving a large distance. Make sure to maintain adequate
maneuvering space when flying with the remote controller B.
· When switching the GNSS to the BeiDou satellite positioning system in DJI
Pilot 2, the aircraft only uses a single positioning system and the satellite
search capability becomes poor. Fly with caution.

Return to Home
The Return to Home (RTH) function returns the aircraft back to the dock or the
alternate landing site when the GNSS signal is strong. RTH can be triggered in
three ways: userinitiated triggers, the aircraft has low battery, or the
control signal between the dock and the aircraft is lost. Alternate Landing
will be triggered if the dock is not suitable for landing. In this case, the
aircraft will fly to and land on the alternate landing site. Flight task will
be interrupted and RTH will be triggered if any of these situation occurs: ·
The aircraft approaches the GEO zones, or the flight distance approaches the
maximum distance.
The GNSS signal is poor during a flight route task. · RTH is triggered in DJI
FlightHub 2. · If the Intelligent Flight Battery level is low, low Battery RTH
will be triggered. · If the aircraft disconnects from the dock, Signal Lost
Action (Return to Home or Continue Task) will be triggered.
· Make sure to set an appropriate RTH Altitude when creating flight task
plans. The RTH altitude should also be at least 5 m lower than the altitude
limit of the GEO zone.
· The RTH feature will be disabled when the GNSS signal icon is red, or the
GNSS is unavailable.
· GEO zones may affect the RTH. Avoid flying near GEO zones. · The aircraft
will exit RTH if the lighting and environment conditions are to
complex to complete RTH, even if the vision systems are working properly.
Advanced RTH
When Advanced RTH is triggered, the aircraft will automatically plan the best
RTH path, which will be displayed in DJI FlightHub 2 and will adjust according
to the environment. The user can cancel RTH after gaining aircraft control in
DJI FlightHub 2. RTH can also be cancelled by pressing the Flight Pause button
or the RTH button on the remote controller B after gaining aircraft control.
After exiting RTH, users will regain control of the aircraft.
