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

ElementVFR Minimum
Visibility≥ 5 km (standard) – varies by airspace and altitude
Cloud separation1000 ft vertical / 1500 m horizontal (above 3000 ft AGL)
Remain clear of cloudsMandatory in all cases
Daylight operationTypically required unless equipped and rated for Night VFR
In sight of surfaceRequired for Special VFR and below certain altitudes

VFR Flight Planning

  • No IFR flight plan required
  • In some cases, VFR flight plan is optional or recommended
  • Pilots must comply with airspace structures, ATC clearances, and traffic procedures
  • Must always see and avoid other aircraft

VFR in Different Airspace Classes

ClassVFR Allowed?Clearance Needed?
A❌ Not permitted
B✅ (rare in Europe)Yes
CYes
DYes
ENo (advisory service available)
GNo

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.

  • Requires explicit ATC clearance
  • Pilot must remain clear of cloud and in sight of ground
  • Visibility ≥ 1500 m (or 800 m for helicopters)

Night VFR

  • Requires specific equipment, training, and authorization
  • May involve route restrictions, weather minima, and ATC clearance in some airspace

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

Tips for VFR Pilots

  • ✅ Always check weather, NOTAMs, and airspace before departure
  • ✅ Carry up-to-date VFR charts and ATC frequency guides
  • ✅ Use LearnATC to practice circuit entries, position reporting, and airspace navigation
  • ✅ Maintain visual scanning to ensure see-and-avoid traffic safety
