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.
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 |
Class | VFR Allowed? | Clearance Needed? |
---|---|---|
A | ❌ Not permitted | — |
B | ✅ (rare in Europe) | Yes |
C | ✅ | Yes |
D | ✅ | Yes |
E | ✅ | No (advisory service available) |
G | ✅ | No |
A variation of VFR that allows flight within a control zone (CTR) below standard VFR weather minima.
