Identify which design patterns are used

class Aircraft {  private int capacity;   private String name; } 
class FirstClassCabinAircraft extends Aircraft { } 
class ViewingAreaAircraft extends Aircraft { } 
class CommunicationsSystemAircraft extends Aircraft { } 
class FirstClassCabinCommunicationsSystemAircraft extends Aircraft { }

I was unable to identify What is wrong with the design? Which design pattern would be suitable to remove deficiencies in the design. Can someone please help me Thanks.
