Flight mode
GDU Byrd supports the following three flight modes:
1. P mode (positioning mode)
When the GPS signal is good, the GPS module is used to maintain the aircraft’s position;
When the GPS signal is not so good or is lost, it will turn to the visual and acoustic positioning
When both GPS positioning and the vision positioning do not work, only the attitude stabilization
is provided.
2. F Mode (Course lock mode)
In this mode, forward control of the aircraft is related to the direction the pilot is facing and is not
dependent upon the direction of the nose of the aircraft. Forward is forward even if the nose of the
aircraft is pointing backward. This allows new pilots to enjoy flying while learning to control the
orientation of the aircraft. This mode relies on GPS data, so please use it when GPS signal is good.
3. A mode (Attitude mode)
In this mode, GPS positioning and the visual and acoustic positioning are not used and only the
attitude stabilization is provided. It is a manual mode and should only be used by experienced
pilots.
※ To change flight modes, please use the FLIGHT MODE switch on the remote control.
RTH mode
GDU Byrd has the function of returning to home automatically. If the home point is recorded
successfully before the flight, then the aircraft will return to home point and land automatically
when connection between the remote and the aircraft is lost. The following three conditions can
cause this to happen: return to home is activated on remote control, when aircraft reaches low
battery and when the aircraft loses contact with the remote control.
1. Home point
Home point refers to the point at which the aircraft has been unlocked for the first time
successfully and in Mode P and the GPS signal is good. Home point will only be logged if starting
off in MODE P. IT WILL NOT WORK IF FLIGHT IS STARTED IN OTHER MODES.
2. RTH mechanism
When this mechanism is started,the aircraft will rise or descend to the pre-set height (if the current
height is lower than the pre-set height, the aircraft will rise to the pre-set height. If it is higher, and
the aircraft will descend to the pre-set height) and it will fly to the point above the home point and
hover for five seconds before slowly landing.
10
※ Connection between remote controls and mobile equipment are different for different Byrd models
(WiFi/USB connection) and the specific connection is subject to actual conditions.
※ When return to home is activated, the aircraft WILL NOT avoid obstacles. Please make sure that the
height is set to avoid any obstacles between you and the aircraft. IF YOU CANNOT SEE THE
AIRCRAFT, DO NOT ACTIVATE RETURN TO HOME.
※ Use the parameter adjustment software to change the altitude of the aircraft when return to home is
activated. A safe altitude is dependent upon the environment in which you fly.The return altitude can
be set through the FCS Configuration Software or the Flight setting page in the APP.
3. Return to home (RTH)
During flying, automatic return can be realized by pressing “Return to home” (RTH) button
in the remote control or click the RTH icon on the APP interface.
4. RTH in low battery
Before RTH automatically happens, there is a warning issued to the pilot regarding the state
of the flight battery.
Low battery warning
When the aircraft power is less than 30%, low battery warning will be activated and APP will
send alarm to you, so that you can return ASAP.
RTH in severe low battery
When the electric quantity is less than 20%, the battery is serious low and the aircraft will
return to home automatically.
11
5. Out-of-control return
In normal conditions, the GPS signal is good, the compass works normally and the aircraft will
record the home point successfully. If the signal between the remote controller and the aircraft is
interrupted or lost, the aircraft will hover until signal is regained. If the signal interruption lasts for
over three seconds, the aircraft will return to home automatically. During returning, if the signal is
back to normal, the returning will be stopped and the pilot can regain control of the aircraft.
※ When GPS signal is not good enough, automatic return won’t work.
Aircraft status indicator
The flight status of GDU Byrd can be judged by two groups of LED indicators at the head and tail
of the aircraft. Their locations are as shown in the following picture.
The two groups of LED indicator lights show the current status of the flight control system
through different groups of colors and flickers. See the following table for more details.
12
Vision positioning system
This positioning system consists of the visible light camera and the ultrasonic module. The former
is used to obtain the position information of the flight to provide reference for the horizontal
direction of the aircraft. And the latter will judge the current flight height to provide reference for
the height from the ground to maintain the flight at a certain height.
This system is adaptable to the environment in which the height is lower than 6 meters, where
there is no GPS signal or the GPS signal is not good enough. It is particularly suitable for indoor
flight.
13
The precision of the visual and acoustic system can be affected by the illumination intensity and
the surface texture of articles. And the ultrasonic will not measure the distance in certain damping
materials. If both vision and ultrasonic do not work, the flight mode will be turned into the
Attitude mode automatically. Therefore, please notice the following conditions during flight:
The normal flight height of this system ranges from 0.2m to 6m. Please stay in this range when
the aircraft is used indoor;
The illumination condition is 10 lux–100000 lux;
Within the required range of the illumination conditions, all textures could be used to position
the flight except pure colors (such as pure black, pure red, pure white and pure green);
Be cautious on the surface where there is intensive reflected light or inverted images;
The flight speed should not be too fast and the highest speed should not exceed 8m/s(17mph).
The maximum flight inclination should not be more than 30°.
The range of flight temperature is -10℃-55℃(14 F to 131 F).
The flight altitude should not be more than 4000 meters (13,000 feet).
※ In Mode P and when the GPS signal is lost or not good enough, the system will turn to the visual and
acoustic positioning mode and no manual operation is needed.
※ This system is only open to GDU Byrd Advanced/Premium version.
