I created a new simulation project called 'ski_jumper_handout':

In these simulations I have chosen to use the following angles of attack: **5° (25°)** and **10° (30°)**.

By comparing the two solutions we notice that the increase of the AoA corresponds roughly to a 14% increase of the lift (for 5° L≈246 N, for 10° L≈280 N) while the drag increases approximately only by 8% (for 5° D≈162 N, for 10° D≈175 N).

**Therefore the choice of the AoA of 10° is evidently the best, since it offers the biggest lift-to-drag ratio.**
