How can I know the coordinates that the aircraft has moved along the path. If i don't know the position and direction?

I understand that speed, time, and the direction and position of the aircraft are necessary to make an aircraft move. But if we only know the direction and position of the aircraft at first, how can I know the coordinates that the aircraft has moved along the path if we don't know the position and direction?

The speed is 50m/s, the first direction of the rider is 0 degrees based on the azimuth, and the time is set to dt=0.1s. In this situation, can the aircraft pull out the coordinates along the path? And I'm also curious about how to draw those coordinates.

hello

I have some difficulties to understand what your problem is

the aircraft is a body subjected to forces (engine thrust, aerodynamic forces , gravity)

so you have to solve those equations and you get your solution
