A pictorial electrical diagram provides

• A. Shows a detailed circuit diagram
• B. Shows color coding only
• C. Uses standard electrical symbols
• D. Shows a pictorial sketch instead of electrical symbols

Answer: (D)

Pictorial diagrams are drawn to resemble the actual hardware and its layout. They show components as pictures or simple drawings placed in roughly the same positions as they appear in the aircraft, so you can quickly recognize parts and understand how wires connect in the real world. Because of that visual, non-symbolic approach, a pictorial diagram presents a pictorial sketch rather than a detailed circuit using standard electrical symbols. Color coding may be used for clarity, but the defining feature is the depiction of components as pictures rather than symbolic circuit diagrams.
