Definition#
VFR stands for Visual Flight Rules. These are aviation regulations that permit a pilot to operate an aircraft by maintaining visual reference to the terrain, horizon, and other aircraft. VFR is one of two sets of flight rules defined by ICAO; the other is IFR (Instrument Flight Rules).
Weather Minimums#
VFR flight requires specific minimum weather conditions, though the exact values vary by airspace class and jurisdiction. In the United States (FAA regulations), common minimums include:
| Airspace | Visibility | Cloud Clearance |
|---|---|---|
| Class B | 3 SM | Clear of clouds |
| Class C/D | 3 SM | 500 ft below, 1,000 ft above, 2,000 ft horizontal |
| Class E | 3 SM | 500 ft below, 1,000 ft above, 2,000 ft horizontal |
| Class G (day, ≤1,200 AGL) | 1 SM | Clear of clouds |
"SM" stands for statute miles. Cloud clearance requirements ensure pilots have enough time to see and avoid other aircraft and terrain.
When VFR Applies#
VFR is the default mode of flight for general aviation. It is used for:
- Recreational and training flights
- Cross-country flights in fair weather
- Helicopter operations in good visibility
- Many bush and backcountry operations
VFR vs IFR#
The key distinction: under VFR the pilot is responsible for see-and-avoid separation from terrain and traffic. Under IFR, air traffic control provides separation services and the pilot navigates primarily by instruments.
