Part 4/8:
The dorsal fin serves not only to stabilize the aircraft in various flight conditions but also to stall at higher angles of attack. It helps manage airflow around the rudder more efficiently, which is akin to design strategies used in some fighter jets, particularly when the aircraft experiences a significant slip angle. Despite its advantages, the fin does not bear any structural load—this distinction plays a significant role in understanding the missed fin's implications on flight safety.
