def control_surfaces(segment):
"""
Updates control surface deflections from solver unknowns
Parameters
----------
segment : Segment
The mission segment being analyzed
- assigned_control_variables : Data
Control variable configurations
- {control_type}.active : bool
Whether control is active
- {control_type}.assigned_surfaces : list
Surface names for each control group
- state.unknowns : Data
Solver unknown values
- state.conditions.control_surfaces : Data
Results data structure
- analyses : list
Analysis modules containing vehicle definition
Returns
-------
None
Updates segment state and vehicle model directly
Notes
-----
This function applies control surface deflection values from the solver's
unknowns to both the vehicle model and results data structure. It handles
all types of control surfaces including elevators, slats, rudders, flaps,
and ailerons.
The function processes:
1. Elevator deflections
2. Slat deflections
3. Rudder deflections
4. Flap deflections
5. Aileron deflections
6. Spoiler deflections
**Control Surface Types**
Supported controls:
- Elevator
- Slat
- Rudder
- Flap
- Aileron
- Spoiler
**Major Assumptions**
* Valid control surface definitions
* Proper surface assignments
* Compatible deflection values
* Well-defined vehicle geometry
