What is the purpose of the visual flight rules (VFR) to IFR transition?

The purpose of the VFR to IFR transition is primarily to provide a structured and safe method for pilots to change from visual navigation, which relies on the pilot's ability to see and interpret the outside environment, to instrument navigation, which relies on the aircraft's instruments and navigation aids. This transition is especially critical in low visibility conditions, where visual references may be severely limited or nonexistent. By having a defined transition process, pilots can maintain safety during these challenging conditions.

When transitioning to IFR, pilots receive specific instructions from air traffic control that help them safely navigate and communicate their intentions, ensuring that they can operate within controlled airspace while adhering to the protocols and regulations associated with instrument flying. This process is vital for preventing accidents and ensuring orderly air traffic flow in conditions where visual navigation is not possible.
