What are the two main types of navigation used in aviation?

The correct answer focuses on the two primary methods used for navigating aircraft: Visual Flight Rules (VFR) and Instrument Flight Rules (IFR). VFR navigation relies on the pilot's ability to see and interpret visual cues from the environment, such as landmarks, terrain, and weather conditions. It is typically used when the weather is clear, and pilots can maintain a visual reference to the ground. On the other hand, IFR navigation is utilized when visibility is poor or when flying through clouds. This method depends on instruments within the aircraft, allowing pilots to navigate safely and effectively by following prescribed routes, utilizing air traffic control, and ensuring they maintain appropriate altitudes.

The distinction between these two navigation types reveals their intended use based on weather conditions and pilot visibility, which is fundamental for flight safety and operational efficiency. This understanding is essential in aviation for ensuring that pilots can select the appropriate navigation method based on current conditions and flight requirements.
