A sectional chart shows an area labeled 'P-40' around Camp David. What does this designation mean?

Why: The Remote Pilot Study Guide describes prohibited areas as airspace of defined dimensions within which flight is prohibited for security or other reasons associated with the national welfare, charted as 'P' followed by a number (e.g., P-40 around Camp David). Under 14 CFR § 107.45, a remote pilot may not operate in a prohibited or restricted area without permission from the using or controlling agency.

• This describes restricted areas, which are tied to active/inactive hours and hazardous activities, not prohibited areas, which are a distinct and more absolute category.
• This invents an unrelated parachute-jump-area scenario; prohibited areas have nothing to do with parachute operations.
