TermDefinition
AGLRefers to the vertical height of the aircraft relative to the take-off point.
AltitudeRefers to the vertical height of the aircraft relative to sea level.
Yaw AngleIt is used to set the position where the nose of the aircraft is facing. The default is to follow the route. When the point of interest has been added, it is often set in conjunction with the point of interest, that is, the yaw angle of the aircraft is set to turn to the point of interest.
Gimbal pitchThe observable range of the gimbal camera, that is, the angle from the top to the bottom (0° ~ 90°).
Finish ActionRefers to the actions that the aircraft will perform after finishing the waypoint mission.
Lost ActionRefers to the actions that the aircraft will perform when the flight application displays a warning saying “Aircraft disconnected.” during flight.

Segment ActionRefers to the actions performed by the camera, the gimbal, and the aircraft during the flight segment formed between the current waypoint and the next waypoint.
Waypoint ActionRefers to the actions performed by the camera, gimbal, and aircraft at a specific waypoint.
