Definition
A set of FAA regulations that allow a pilot to operate an aircraft in weather conditions generally clear enough for the pilot to see where the aircraft is going by looking outside. VFR specifies minimum visibility and cloud clearance requirements that must be met for flight without reference to instruments alone, and the pilot is responsible for seeing and avoiding other aircraft, terrain, and obstacles.
Plain English
Rules for flying when the weather is good enough to navigate and stay clear of other aircraft by looking out the window.
Context Anchor
Pilots encounter VFR when checking weather, planning a route, choosing an altitude, entering certain airspace, or deciding whether a flight can legally continue.
Derivation
From Latin visualis (relating to sight). The term simply means rules based on flying by sight — distinguishing it from Instrument Flight Rules (IFR), which govern flight conducted by reference to cockpit instruments.
Why Pilots Care
Determines whether a pilot without an instrument rating can legally fly a given route and helps avoid entering weather that could cause disorientation.
Intuition Check
Do not read VFR as simply “flying on a nice day.” VFR is a specific set of legal weather and operating rules, not just a general feeling that the weather looks good.
Example Sentence 1
The weather briefing showed clear skies and 10 miles of visibility, so the student planned a VFR cross-country flight to the practice area.
Example Sentence 2
Because the ceiling and visibility allowed it, the cross-country trip was completed entirely under Visual Flight Rules.
