FAA Sport Pilot Airplane (SPA)Airspace and NavigationEasy

A pilot reviewing a sectional chart near Washington, D.C. notices an area outlined with a blue hatched border and labeled 'P-40.' What does this designation mean for VFR flight planning?

  1. AThe area is only hazardous during charted times listed in the Chart Supplement
  2. BFlight within the area is prohibited to all aircraft, regardless of prior arrangement
  3. CThe area requires a two-way radio contact with ATC before entry, but is otherwise open
  4. DThe area is reserved exclusively for parachute jump operations
Show answer & explanation

Correct answer: B. Flight within the area is prohibited to all aircraft, regardless of prior arrangement

A 'P' designation identifies a Prohibited Area, established for security or other reasons of national welfare. Unlike a Restricted Area, entry is never permitted, even with ATC clearance.

Why the other options are wrong

  • A. Time-limited hazard areas describe Alert or Restricted Areas, not Prohibited Areas.
  • C. This describes a Restricted or National Security Area, not a Prohibited Area.
  • D. Parachute operations are shown with a separate symbol, unrelated to the 'P' designation.

Prohibited Area

A block of airspace within which flight is prohibited for security or other reasons, charted with a blue border and the letter 'P' followed by a number.

  • Charted as 'P-XXX' with blue hatched border
  • No entry is allowed, even with ATC clearance
  • Established for national security or safety reasons
  • Examples include areas over the White House and Camp David

Memory trick: 'P' is for Positively No Entry!
