1) Map module: display the map interface;
2) HUD module: displays UAV stance, horizontal speed, vertical speed, flight height,
battery information and data transmission signal;
a. Battery information: when the battery is high, the background color of voltage turns
to green; when the voltage triggers the primary low voltage protection, the background
color turns to yellow; when the voltage triggers secondary low voltage protection, the
background color turns to red and starts to flash; the details of low voltage protection
are as per "Fault Protection";
b. Data transmission signal: when the data transmission signal is in good status, it is
green; when the flying instructions for GUIDED are poorly received , if the data
transmission is poor, it will prop up the dialog box; if the connection is broken off (when
data transmission is 0%), it turns to red;
3) Warnings: for any dangers found in flying control or linking;
4) direction module: displays the head's direction, vertical speed, horizontal speed,
number of satellites, horizontal accuracy, distance from home, height, target GUIDED
distance and current mode (when the background is green, it is of manual mode, while
yellow flashing shows other modes);
5) Control module: sending command in real-time to control the UAV;
6) Remote control: display the current control feedbacks of remote in real-time;
