Airspace and weather

VFR weather minimums by airspace (3-152)

Visibility and cloud clearance for every class of airspace, explained simply.

Basic VFR weather minimums tell you how much flight visibility you need and how far you must stay from clouds. They change with the class of airspace, your altitude, and (in Class G) whether it is day or night. Most of the chart is the "3-152" rule: 3 statute miles visibility, 1,000 ft above, 500 ft below and 2,000 ft horizontally from clouds.

Source: 14 CFR 91.155. Class G at night has one exception: in the traffic pattern within half a mile of the runway, 1 statute mile and clear of clouds is allowed (91.155(b)(2)).

Two more rules near airports

  • Ceiling: you may not fly VFR beneath a ceiling lower than 1,000 ft inside controlled airspace that goes down to the surface at an airport (91.155(c)).
  • Visibility to take off or land: in the surface area of Class B, C, D or E airspace, ground visibility at the airport must be at least 3 statute miles. If none is reported, use flight visibility (91.155(d)). Below these, you need a special VFR clearance.

How to remember it

Learn "3-152" first, because it covers Class C, D and E below 10,000 ft. Then learn the exceptions: Class B is "clear of clouds", high altitude is "5 and 1-1-1", and low Class G in the daytime is "1 and clear". Your flight planner and a real METAR from the METAR decoder are good places to practice applying them.

Common questions

What does 3-152 mean?

3 statute miles visibility, 1,000 ft above, 500 ft below and 2,000 ft horizontally from clouds. It applies in Class C, D and E below 10,000 ft MSL.

What are the VFR minimums in Class B airspace?

3 statute miles visibility and clear of clouds.

Why are the minimums higher at 10,000 ft and above?

Airplanes fly faster up high, so you need more visibility and more room from clouds to see and avoid traffic: 5 statute miles, 1,000 ft above and below, and 1 statute mile horizontally.
