What is assured in a Minimum Safe Altitude (MSA)?

• A. 500' obstacle clearance
• B. 1000' obstacle clearance
• C. 2000' obstacle clearance
• D. No obstacle clearance

Answer: (B)

The Minimum Safe Altitude (MSA) is designed to provide a certain level of obstacle clearance while navigating in the vicinity of an airport, particularly during an approach. Specifically, the correct choice indicates that a clearance of at least 1,000 feet above the highest obstacle within a defined radius is assured. This altitude is meant to enhance situational awareness and safety, ensuring that pilots can operate without the risk of colliding with obstacles such as buildings or terrain. By providing this buffer, pilots can maintain a degree of operational flexibility, especially in areas with varying terrain and potential obstructions. The other options do not reflect the MSA standards as established in aviation regulations. For instance, an altitude providing only 500 feet of clearance may not be sufficient in many circumstances, especially in mountainous areas or places with high structures. Similarly, 2,000 feet of obstacle clearance is more than what is typically required at MSA, making it an unnecessary elevation for ensuring safety in the context of the MSA. Thus, the 1,000-foot standard balances safety and operational efficiency appropriately.
