class Vertical_Tail_All_Moving(Vertical_Tail, All_Moving_Surface):
"""
A class representing an all-moving vertical tail that provides directional control
and stability.
Attributes
----------
tag : str
Unique identifier for the surface, defaults to 'vertical_tail_all_moving'
sign_duplicate : float
Sign convention for duplicate surface deflection, defaults to -1.0
(opposite deflection for yaw control)
Notes
-----
The all-moving vertical tail combines the functions of a vertical stabilizer and
rudder by pivoting as a complete surface. It inherits from both Vertical_Tail and
All_Moving_Surface to combine their functionality.
See Also
--------
RCAIDE.Library.Components.Wings.Vertical_Tail
Base class providing vertical tail functionality
RCAIDE.Library.Components.Wings.All_Moving_Surface
Base class providing pivoting surface functionality
RCAIDE.Library.Components.Wings.Control_Surfaces.Rudder
Alternative yaw control using conventional rudder
"""
def __defaults__(self):
"""
Sets default values for the all-moving vertical tail attributes.
Notes
-----
See All_Moving_Surface.__defaults__ and Wing.__defaults__ for
additional inherited attributes.

"""
Creates a reflected copy of the vertical tail over the x-z plane.
Returns
-------
Component
Reflected vertical tail with appropriate deflection sign
Notes
-----
* Used when vertical tail's symmetric attribute is True
* Deflection is reflected according to sign_duplicate convention
* Should be called after setting control surface deflections
