Which symbol stands for Special Electronic Installation?

• A. A
• B. E
• C. F
• D. T

Answer: (B)

Reading aerodrome symbols, each marking on the diagram maps to a facility category in the legend. This lets you quickly identify what kind of installation is nearby and why it matters for operations. For Special Electronic Installation, the symbol used is the letter E. That association comes from the chart legend, which assigns E to that category, so E is the mark you look for when you need to know there’s a special electronic installation present. The other letters correspond to different types of installations, not to Special Electronic Installation, so they wouldn’t indicate that category. Keeping the legend in mind helps you read the airfield layout accurately and understand any electronic sources that could affect movement or safety.
