What is required for a Contact IAP?

For a Contact IAP (Instrument Approach Procedure), the requirements include being clear of clouds and having a minimum flight visibility of 1 statute mile. This condition is essential because a Contact IAP is designed for pilots to visually navigate and land while still adhering to certain cloud clearance and visibility requirements. The 1 statute mile visibility ensures that the pilot has adequate visual reference to the runway environment and surrounding terrain, which is crucial for maintaining safe flight operations during the approach phase.

In contrast to other options, the requirement for being clear of clouds ensures that pilots can maintain visual contact with the ground and the runway without relying solely on instrumentation. While there may be situations where runway insight is important, and daylight can aid in visibility, the primary regulation for a Contact IAP is based on cloud clearance and visibility, which underscores the necessity for pilots to engage in visual flight conditions during this type of approach.
