Blogs if you don't have forward speed and you don't have vertical speed while up at 2000ft in the air you are hovering! That's not a path.
If you don't have forward speed but you descent at 700ft/min, you are dropping. The angle of your path is then 90 degrees.
If you fly at 130kts and you have no vertical speed you are flying straight and level. The angle of your path is 0 degrees.
So In order to fly a 3 degree path you need to go forward or backward (speed) and you need to descent or climb (vertical speed)
Mate study some physics!
