While the aircraft is travelling between waypoints, you can offset its speed by using the throttle joystick on the remote controller. getMaxFlightSpeed is this offset when the joystick is pushed to maximum deflection. For example, If maxFlightSpeed is 10 m/s, then pushing the throttle joystick all the way up will add 10 m/s to the aircraft speed, while pushing down will subtract 10 m/s from the aircraft speed. If the remote controller stick is not at maximum deflection, then the offset speed will be interpolated between [0, getMaxFlightSpeed] with a resolution of 1000 steps. If the offset speed is negative, then the aircraft will fly backwards to previous waypoints. When it reaches the first waypoint, it will then hover in place until a positive speed is applied. getMaxFlightSpeed has a range of [2,15] m/s.
The base automatic speed of the aircraft as it moves between waypoints with range [-15, 15] m/s. The aircraft's actual speed is a combination of the base automatic speed, and the speed control given by the throttle joystick on the remote controller. If getAutoFlightSpeed >0: Actual speed is getAutoFlightSpeed + Joystick Speed (with combined max of getMaxFlightSpeed) If getAutoFlightSpeed =0: Actual speed is controlled only by the remote controller joystick. If getAutoFlightSpeed <0 and the aircraft is at the first waypoint, the aircraft will hover in place until the speed is made positive by the remote controller joystick.
As same as Waypoint 1.0 Add a waypoint to the waypoint mission. When a waypoint is added successfully, getWaypointCount will increment by 1. A waypoint will only be valid if the distance (in three dimensions) between two adjacent waypoints is in range [0.5,2000] meters.
