NALYSIS AND ANSWERS TO
FAQ
Ask: it is promoted that the mode toggling fails in the air while the UAV has been
successfully switched immediately, why?
Answer: In the case of bad signal transmission, the communication between the flight
control and ground control station is quite poor. When the ground control station does
not receive the flight control information after a while, the ground control station will
prop up the prompt indicating the mode toggling fails. If the instantaneously blocked
signal is sent to the ground control station once again, then the mode will be switched
successfully. If it is still unsuccessful for a while, you do the re-operation. If the prompt
appear repeatedly, you need to check whether the data transmission signal is table or
not, and it is suggested that, the flight is made when the data transmission signal
remains above 70%. The real-time flight isn't recommended if the data transmission
signal is extremely unstable.
Ask: when you test the lost-control protection on the ground, you switch to the RTL,
LAND or shut down the control, the motor will stop, is the phenomenon normal? Will
the same problem occur in the air?
Answer: the functions of RTL and LAND: the flight control program will read the value
of barometer to determine the height of aircraft; when the aircraft returns and lands on
the ground, the flight control program will stop the motor to avoid the accident. Because
it is tested on the ground, the flight control believes that the aircraft has returned and
landed, and then it stops the motor. This phenomenon is normal, and no similar
phenomenon will occur in the air.
Ask: when do you need to calibrate the magnetic compass?
Answer: 1. you have moved or disassembled GPS or flight control, or the current
location is quite distant from the area when last time you calibrated the magnetic
compass, for example, you have moved to another city, and you need to calibrate the
magnetic compass.
