What defines the Mode C Veil?

What defines the Mode C Veil?

• A. Airspace above 10,000 feet MSL around Class B airports
• B. Airspace within 30 NM of the primary airport within Class B airspace
• C. Airspace where only gliders can operate
• D. Airspace without any transponder requirements

Answer: (B)

The Mode C Veil is specifically defined as the airspace within a 30 nautical mile radius from the primary airport of a Class B airspace system, extending from the surface up to the ceiling of that Class B airspace. This designation requires aircraft operating within this veil to be equipped with a Mode C transponder, which allows air traffic control to receive altitude information. This is particularly important for maintaining safety and managing air traffic in congested areas near major airports, where the potential for conflict between high-density traffic and surrounding operations exists. Understanding this requirement helps pilots ensure compliance when flying in these areas and promotes better situational awareness. The other explanations do not accurately describe the Mode C Veil. For instance, airspace above 10,000 feet MSL is not a defining characteristic of the Mode C Veil, and there are no restrictions on glider operations specifically tied to this airspace. Additionally, while transponder requirements apply within the Mode C Veil, airspace without any transponder requirements does not relate to this particular classification.
