Why do some planes have two tails?
One advantage of having twin vertical stabilizers is that the location of vertical tails helps in having control authority at high alpha (where the fuselage/wing can blank a single vertical stabilizer). In modern stealth aircraft, having a twin tail enables them to be canted, helping in reducing RCS.
Why is tail fin important?
The tail fin (called the caudal fin) is the main source of movement for most fish. It’s like the motor on a boat. It shouldn’t be surprising then, that it is shaped differently according to how the fish needs to move most of the time. This helps the fish to move more efficiently through the water.

Why are twin tails used in military aircraft?
Use twin tail designs. I understand for military aircraft that the benefit is it allows for a small tail cross section. Reducing the chance of it being damaged in combat. In the case of the A225 and other similarly designed cargo aircraft it means the rear of the aircraft can be more easily designed as a cargo hatch.
What’s the difference between a twin tail and a pigtail?
In the context of hairstyles, the usage of the term pigtail (or twin tail or twintail) shows considerable variation. The term may refer to a single braid, but is more frequently used in the plural (“pigtails”) to refer to twin braids on opposite sides of the head.
Why do you need a twin tail propeller?
Separating the control surfaces allows for additional rudder area or vertical surface without requiring a massive single tail. On multi-engine propeller designs twin fin and rudders operating in the propeller slipstream give greater rudder authority and improved control at low airspeeds, and when taxiing.
