Autopilot / Flight Controller – All RPAs have a Flight Controller or Autopilot. Common examples include the DJI Naza or A2 or the 3DR Pixhawk or APM. Ready-to-Fly aircraft usually have their own specialised controller. A typical autopilot system may consist of one or more modules or boxes. These may include a PMU (Power Management Unit), MCU (Main Control Unit), a GPS/Compass Module and an IMU (Inertial Measurement Unit). Some controllers have separate units for each of these while others have them integrated into one unit.
Camera Gimbal – A camera gimbal is a motorised attachment for an RPA that enables a camera to remain stable while the RPA is moving. Additionally, a gimbal maintains a constant direction which the camera is pointed in utilising its on-board servos or motors
Data Link – Data links transmit information between autopilot systems and information technology such as PCs, tablets or smartphones. This link allows the user to pilot the RPA from their own personal platform. This may also allow for enhanced automation, waypoint and flight planning capabilities. Many programs are available for PC’s, Apple products and Android phones.
ESC – ESC stands for electric speed controller. ESC’s are similar to a remote switch that regulate how much current flows through an RPA’s motors, hence how fast the propellers spin and how much lift the aircraft generates
First Person View – Abbreviated FPV, First Person View systems allow for a video stream to be delivered to the Remote pilot station (RPS). This makes the Remote Pilot (RP) feel as if he/she is on board the aircraft, allowing for ease of control and increased visibility and flying precision. Note however that in Australia, a Remote Pilot is required to maintain Visual Line of Sight at all times, so an observer must be used if flying FPV.
Retractable Undercarriage – Retractable undercarriage systems can be used to enhance a Gimbal’s freedom of movement, whilst sometimes also reducing drag on the aircraft. Just remember before landing; AYWD – Are Your Wheels Down?
Transmitter/Receiver Systems – More commonly known by terms such as remotes or ariels, Transmitter/Receiver systems (abbreviated Tx and Rx) allow control inputs to be transmitted from the remote pilot station (RPS) to the RPA.
Video Overlay Software – Video overlay software can be used as an FPV accessory. Usually on board the RPA, a video overlay system is connected to an autopilot system, imposing critical flight data such as airspeed, altitude and attitude onto the FPV video stream. This data can greatly enhance the accuracy and safety of operating an RPA.
