Introduction to the flight axis and its terminologies
Until now, we have covered flight terminologies. We can say that a multi-copter hovers when the lift force is equal to the weight of the drone and the cruise speed in the air, which can be termed as cruising in three-dimensional (3D) space. To ease the calculations, we have considered a drone working in 3D space under the major three universal axes, namely, the X-, Y-, and Z-axes. These help us design and program the drone. The balance and uniform distribution of mass and forces across these three axes help us to attain stable flight. Let’s look at the movement of the drone across these axes and its terminologies more.

As discussed above, the movement of s drone across the X-, Y- and Z-axes of the 3D plane is coined by roll, pitch, and yaw movement, respectively. A brief description of these movements is given...
