Visual Flight Rules (VFR)
Definition
Visual Flight Rules (VFR) are a set of regulations that allow pilots to operate an aircraft in weather conditions clear enough to fly by visual reference to the ground, horizon, and other aircraft, rather than relying solely on instruments. VFR governs most general aviation, flight training, daytime operations, and non-commercial flying.
Purpose
- Enable flight using outside visual cues for navigation and separation
- Reduce dependency on air traffic control and instrument procedures
- Allow simpler operations in uncontrolled airspace or at non-towered airports
- Establish minimum weather and visibility standards for flight safety
Key Requirements
| Element | VFR Minimum |
|---|---|
| Visibility | ≥ 5 km (standard) – varies by airspace and altitude |
| Cloud separation | 1000 ft vertical / 1500 m horizontal (above 3000 ft AGL) |
| Remain clear of clouds | Mandatory in all cases |
| Daylight operation | Typically required unless equipped and rated for Night VFR |
| In sight of surface | Required for Special VFR and below certain altitudes |

VFR in Different Airspace Classes
| Class | VFR Allowed? | Clearance Needed? |
|---|---|---|
| A | ❌ Not permitted | — |
| B | ✅ (rare in Europe) | Yes |
| C | ✅ | Yes |
| D | ✅ | Yes |
| E | ✅ | No (advisory service available) |
| G | ✅ | No |
VFR Phraseology Examples
- “VFR departure to the north at 2500 feet, request taxi.”
- “Entering left downwind runway 27, full stop.”
- “Maintaining VFR, crossing Class E airspace westbound.”
Special VFR (SVFR)
A variation of VFR that allows flight within a control zone (CTR) below standard VFR weather minima.
Night VFR
VFR Limitations
- ❌ Not permitted in cloud, poor visibility, or Class A airspace
- ❌ May be restricted in busy terminal areas
- ✅ Pilots are responsible for terrain and obstacle clearance
- ✅ Must comply with right-of-way rules and maintain situational awareness
