What weather minimums are required for a contact approach?

The correct choice regarding the weather minimums required for a contact approach emphasizes the necessity of having 1 nautical mile (NM) flight visibility and ensuring that the aircraft remains clear of clouds.

This minimum visibility of 1 NM is crucial because it allows pilots to visually identify landmarks and the runway environment, which is essential for safely conducting such an approach. In a contact approach, pilots leverage visual references for navigation rather than relying solely on instrument readings. Additionally, remaining clear of clouds ensures that the pilot can see the landing area and approach path, thereby enhancing situational awareness and safety.

Weather conditions such as clouds being below 1,000 feet, 3 statute miles (SM) visibility with no obstructions, or having a 500-foot ceiling with 3 SM visibility differ from the requirements for a contact approach. These conditions are generally applicable to other types of approaches or operations but do not define the specific parameters that apply to a contact approach, where visual references are paramount for safe maneuvering during descent and landing.
