P

Payload: The amount of additional weight a drone is able to lift in addition to its own weight and batteries. If you attach a camera and gimbal to your drone, the combined weight is the payload.

Pitch: A measure which describes the flight angle along one axis, usually measured from level in case of aerial vehicles.

Pre Flight Planning: The activities conducted by the pilot and flight crew prior to takeoff to ensure that the flight will be conducted safely and in accordance with all applicable standards and regulations. The activity includes, but is not limited to, such things as checking weather, route of flight, airspace, equipment configuration, support personnel, terrain and communications requirements.

Power Distribution Board: is the PDB and is a board that is used on the multicopters to help distribute the power to each of the motors to provide proper stabilization of the unit.

R

Radio Controller: wireless handheld device used to control flight of the drone.

R/C : Abbreviation for Radio Controlled.

RC: Abbreviation for Radio Controlled - it refers to control of a drone via radio waves.

RTF: Ready to Fly - This means the drone is sold with everything needed in the pack. All you need to do is put it together, add batteries and you are ready to use it. It is possible you may need to buy the batteries separately. This fact is usually mentioned on the box.

S

Sense And Avoid: The capability of a UAS to remain well clear from and avoid collisions with other airborne traffic. Sense and Avoid provides the functions of self-separation and collision avoidance.

Servo: A shorter name for servomotor or servomechanism. Aerial vehicles use servomotors for various functions such as pan cameras and wing flaps adjustments which can be controlled from the ground.

sUAS:  acronym for - small Unmanned Aircraft System

T

Throttle: Control that influences the RPM or the speed of electric motors.

Toy grade: The basic level of quadcopters, usually priced under $100, using relatively cheap components. Not very reliable, toy grade quads can still offer a wide variety of functions. They can be an excellent way to start for beginners, as they can still provide a lot of fun, despite the lack of reliability. when you are ready, you can move on to a hobby grade machine or even or more advanced ones, but you have to be ready to pay a higher price.

TX: Abbreviation for transmitter or transmit.

U

UAV: unmanned aerial vehicle. A device that can propel itself through the air without a pilot onboard. Drones and quadcopters are UAVs.

Ultrasonic sensor: A sensor that uses the ultra sound wavelength to communicate with a transmitter. In aerial vehicles, ultrasonic sensors are used for calculating the distance to the ground by bouncing sound waves back and forth. They don't work further than a few meters from the ground.

V

Visual line of sight: is the term that is going to control how the pilot can see the aircraft from the ground without the use of artificial vision.

Visual Observer: A crew member who assists the UAS pilot in the duties associated with collision avoidance. This includes, but is not limited to, avoidance of other traffic, airborne objects, clouds, obstructions, and terrain. Most associated with FPV flying.

VLOS: Acronym for Visual Line of Sight.

W

Waypoint: A set of coordinates which define a point in space. Waypoints are useful in designing various autonomous missions for quadcopters. Mapping out would be impossible without a possibility to define these physical locations.
