The minimum separation for nonparticipating aircraft above FL290 from the vertical limits of Special Use Airspace is ______ feet.

• A. 500
• B. 1000
• C. 1500
• D. 2000

Answer: (B)

Nonparticipating aircraft near Special Use Airspace need a safety buffer from the SUA’s vertical limits to prevent inadvertent entry into potentially hazardous airspace. Above FL290, that buffer is 1,000 feet. This provides a practical margin for navigation errors, wind drift, and any late changes to airspace activity, ensuring the aircraft stays outside the SUA while maintaining safe separation. The other options don’t align with this established minimum. Therefore, the required separation is 1,000 feet.
