Question 6: How do "Aerodynamic Drag Models" influence simulation accuracy, and what methods do you use to ensure the correct modeling of drag forces in aerospace simulations?

Which action should you take?

Choose only one option

Drag models only apply to low-speed, subsonic aircraft

Accurate drag models account for air density, velocity, and surface characteristics, but challenges include modeling turbulent flow and varying conditions

Drag models are unnecessary if the aircraft is tested in a wind tunnel

Drag models are irrelevant as drag does not affect flight performance
