FAR 91.133 — Restricted and Prohibited Areas
FAR 91.133 explains the rules for flying in restricted and prohibited airspace. Learn what's required, who to ask, and how to prep for your checkride.
FAR 91.133 governs how pilots interact with two types of special use airspace: restricted areas and prohibited areas (both designated in Part 73).
The rule has two main parts:
- No entry without permission. You may not operate an aircraft inside a prohibited area at all, and you may not enter a restricted area contrary to its restrictions, unless you have permission from the using or controlling agency.
- Approved operators get flexibility. If you're conducting an approved operation inside a restricted area that creates the same hazards the area was designated for, you may deviate from rules in this subpart that aren't compatible with your operation.
Why it matters: Restricted areas can contain artillery fire, aerial gunnery, or guided missiles — real hazards to non-participating aircraft. Prohibited areas (like P-56 over the White House) are off-limits for national security. Busting either one can mean intercepts, certificate action, or worse. Always check the sectional chart for boundaries and times, and contact the controlling agency (often listed on the chart) before operating anywhere near these areas.
