What this covers

Sample questions

What is the minimum requirement to enter Class B airspace under VFR?

  1. Two-way radio contact with the approach controller
  2. A filed VFR flight plan and a discrete transponder code
  3. Radar contact and a traffic advisory from approach control
  4. An ATC clearance to enter the Class B airspace
Show the answer

D. An ATC clearance to enter the Class B airspace

Class B requires a specific clearance, such as 'cleared into the Class Bravo airspace'. Two-way radio contact is enough for Class C and D, which is why it is the tempting wrong answer here.

Reference: 14 CFR 91.131

The basic VFR weather minimums in Class B airspace are

  1. 3 SM visibility and clear of clouds
  2. 3 SM visibility; 500 below, 1,000 above, 2,000 horizontal
  3. 1 SM visibility and clear of clouds
  4. 5 SM visibility; 1,000 below, 1,000 above, 1 SM horizontal
Show the answer

A. 3 SM visibility and clear of clouds

In Class B a VFR aircraft needs 3 statute miles and must simply remain clear of clouds, because ATC separates all aircraft there. The 500/1,000/2,000 cloud clearances apply in Class C, D and most Class E.

Reference: 14 CFR 91.155

Before entering Class C airspace, a VFR pilot must

  1. receive a clearance that names the Class C airspace
  2. establish two-way radio communication with the ATC facility
  3. file a VFR flight plan with Flight Service
  4. be issued a discrete transponder code by ATC
Show the answer

B. establish two-way radio communication with the ATC facility

Class C requires two-way radio communication to be established before entry, plus a Mode C transponder and ADS-B Out. An explicit clearance is needed only for Class B.

Reference: 14 CFR 91.130
