How does IFR navigation differ from VFR navigation?

• A. IFR requires no ATC guidance
• B. IFR relies on instrument-based navigation and ATC guidance; VFR relies on visual navigation and pilotage
• C. IFR uses only visual cues
• D. IFR is only for large airliners

Answer: (C)

IFR navigation is guided by instruments and ATC discipline. Pilots rely on cockpit instruments and navigation equipment (VOR, DME, RNAV, GPS, ILS, etc.) to determine position, course, and altitude, and they receive routing and separation services from air traffic control. This setup allows safe operation in reduced visibility or instrument meteorological conditions. VFR navigation, on the other hand, is based on seeing and using visual references outside the cockpit plus basic piloting skills like pilotage and dead reckoning. Pilots navigate by landmarks, ground features, charts, and known routes, provided weather permits good visibility and cloud clearance. So the intended distinction is that IFR uses instrument-based navigation with ATC guidance, while VFR uses visual navigation and pilotage. The other statements don’t fit because IFR does involve ATC guidance, IFR is not limited to large airliners, and IFR is not based on visual cues only.
