Support Animation and Rigging

I want to make an airplane animation, that has to follow a path.

The problem is the path has to go like this

straight line, then a spiral like screwdriver modifier 4 times around up, and then a straight line again.

How do you create a path line like that ? (where i have some control over the screwdriver).

Also the plane has to keep a constant speed.
