Warning Areas are typically located how far offshore and may be hazardous to nonparticipating aircraft?

• A. 3 NM off coast
• B. 12 NM off coast
• C. 25 NM off coast
• D. 50 NM off coast

Answer: (A)

Warning areas are offshore airspace designed to warn pilots of potential military activity that may be hazardous to nonparticipating aircraft. They typically begin 3 nautical miles offshore and extend outward over international waters. That 3 NM starting point is the standard boundary from the coast where these warning areas can begin, which is why it’s the correct choice. The activities inside—like military training or live ordnance—pose risks to pilots who are not part of the activity, so awareness and avoidance are important.
