class Avionics(Component):
    """
    A class representing aircraft avionics systems and their power requirements.

    Attributes
    ----------
    power_draw : float
        Power consumption of the avionics system, defaults to 0.0
        
    tag : str
        Unique identifier for the avionics system, defaults to 'Avionics'

    Notes
    -----
    The avionics class models the electrical power requirements of aircraft 
    electronics and instruments. This includes:
        * Flight management systems
        * Navigation equipment
        * Communication systems
        * Display systems
    
    **Major Assumptions**
        * Constant power draw during operation
        * Instantaneous power availability
        * No thermal management considerations
    
    **Definitions**

    'Power Draw'
        The electrical power required by the avionics system during operation
        
    'Bus'
        The electrical distribution system supplying power to the avionics
