Improvements in displaying the direction of movement (predictor)

[bc38]

I propose to add the direction vector of the expected course (predictor) in the form of a line whose length depends on the speed of movement. In the settings, the parameter of the expected rate in minutes is set, i.e. vector length displays the distance traveled from the target (A) to the end of the vector (B) in a given period of time.

The course display type (predictor) is common among marine navigation systems and is also presented in the marinetraffic service

What is the given period of time?

[bc38]

at the speed of movement - 10 km/h course predictor equals - 5 minutes vector length is - 0.83 km

Is there some formula?

У меня нет
