Definition
Aeronautical charts published for the two main categories of flight: Visual Flight Rules (VFR) charts, which depict terrain, landmarks, airspace, and airports for pilots navigating by visual reference to the ground; and Instrument Flight Rules (IFR) charts, which depict airways, navigation aids, intersections, altitudes, and procedures for pilots navigating solely by instruments.
Plain English
Two different kinds of flight maps. VFR charts are used when the pilot can see outside and navigate by looking at the ground. IFR charts are used when the pilot is flying by instruments alone, often in cloud, and must follow published routes and altitudes.
Context Anchor
You see VFR and IFR charts during preflight planning, route selection, weather evaluation, and in-flight decisions about where the airplane can safely and legally go.
Derivation
VFR stands for Visual Flight Rules and IFR stands for Instrument Flight Rules. The chart names simply identify which set of rules the chart is designed to support.
Why Pilots Care
Selecting the correct chart type supports accurate navigation and prevents disorientation or regulatory violations.
Grounding Statement
The chart must match the way the flight is being conducted: visual flying needs VFR chart information, and instrument flying needs IFR chart information.
Intuition Check
Do not assume VFR and IFR charts are the same map with different labels. They are built for different ways of flying: one based mainly on outside visual reference, the other based on instruments and air traffic control guidance.
Example Sentence 1
Before the cross-country flight in clear weather, she reviewed the VFR sectional chart to identify checkpoints along the route.
Example Sentence 2
Before the IFR flight, the crew studied the IFR chart to confirm the assigned airway.
