What is the difference between VFR and IFR?

The distinction between VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) revolves around the conditions under which pilots operate their aircraft. VFR is conducted under visual conditions, meaning that pilots rely on their eyesight to navigate and maneuver the aircraft. This type of flying requires good weather conditions, allowing pilots to see landmarks, other aircraft, and the horizon.

On the other hand, IFR is primarily instrument-based, which means that pilots operate the aircraft using instruments, regardless of external visibility. This is essential in conditions where visibility is limited, such as in overcast weather or fog. IFR allows pilots to navigate safely without relying solely on visual cues, using procedures and regulations set by air traffic control to ensure safety.

The other options do not accurately represent the fundamental difference between VFR and IFR. VFR is not specifically associated with time-based operations, nor does it require a higher certification than IFR; both types of flying have their own licensing requirements. Furthermore, VFR can be conducted during both day and night, provided the aircraft is equipped appropriately and the pilot meets any required qualifications for night flight.
