Which is a key difference between Y and Z IAP?

• A. Type of navigation aid used
• B. Minimum visibility requirements
• C. Approach category classification
• D. Procedure complexity

Answer: (B)

The key difference between Y and Z Instrument Approach Procedures (IAP) often lies in the minimum visibility requirements. Each procedure is designed with specific criteria that must be met for a safe approach and landing. In the case of Y and Z procedures, the "Y" approach may be developed with slightly more lenient visibility requirements, allowing for operations with lower visibility conditions, while the "Z" approach is typically more stringent, requiring better visibility to ensure safety during the approach phase. This distinction is crucial, as it directly impacts the pilot's decision-making regarding which procedure to use based on the prevailing weather conditions. Understanding minimum visibility requirements is essential for pilots to ensure compliance with regulations and to execute successful approaches under varying flight conditions.
