FAA Sport Pilot Airplane (SPA)Airspace and NavigationMedium

A pilot wants to transit through Class B airspace surrounding a major airport. The pilot contacts approach control and reports the request. Which response from ATC would allow the pilot to legally enter the Class B airspace?

  1. A'Cessna 456CD, cleared into the Class Bravo airspace'
  2. B'Cessna 456CD, radar contact'
  3. C'Cessna 456CD, squawk 0451'
  4. D'Cessna 456CD, remain clear of Bravo airspace'
Show answer & explanation

Correct answer: A. 'Cessna 456CD, cleared into the Class Bravo airspace'

14 CFR 91.131 requires that an aircraft receive an explicit ATC clearance before entering Class B airspace. Only a specific statement authorizing entry, such as 'cleared into the Class Bravo airspace' or 'cleared to enter the Class Bravo,' satisfies this requirement; radar contact and squawk code assignment alone do not.

Why the other options are wrong

  • B. 'Radar contact' only means the aircraft is identified on radar, not cleared to enter.
  • C. Assigning a transponder code does not constitute clearance into Class B airspace.
  • D. This instruction explicitly tells the pilot not to enter.

Class B Clearance Requirement

Unlike Class C and D, Class B airspace requires an explicit ATC clearance to enter, not just two-way radio communication.

  • Governed by 14 CFR 91.131
  • 'Radar contact' or a squawk code assignment is NOT clearance
  • Clearance must explicitly state the aircraft may enter Class Bravo airspace

Memory trick: 'B is for Big permission' — Bravo needs a real go-ahead, not just a nod.
