how to know a intersection point at a line with specific slope?

i have coordinates data and altitude data(this is aircraft data).

I want to get a data(coordinates) when a line(consisting of cooridnates) intersect the red line

and even if, i didn't plot altitude data here, if you know how to get a data(altitude) together, let me know please

thanks!

As always would make it possible for somebody to have a chance if you would attach your data as .mat file containing the data with which you make the above plot and the code that did so...then we at least are able to get where you are...otherwise, we have to make up stuff first.

Do you want to find out the intersection point coordinates for two lines in 3-D plane?

Do you have your line as an equation? You could then tabulate the values of x,y,z to find the points. Then you can find the distance between the points of your line and the points of your aircraft data, when the distance is below a certain value (as it may not be exactly the same place) you can assume that these intersect.
