What is the minimum altitude allowed during a restricted low approach?

The minimum altitude allowed during a restricted low approach is set at 500 feet. This altitude is established to ensure safety during flight operations while still allowing pilots to gain situational awareness and conduct necessary maneuvers. The 500-foot threshold offers a balance between the need for a low approach for specific operational requirements and the safety of the aircraft, crew, and any ground occupants.

Choosing this minimum altitude also aligns with various regulations and procedural guidelines that govern low-level flight operations. For instance, coming in at a lower altitude could pose risks related to obstacles, terrain, and proximity to populated areas, which is why 500 feet is deemed the minimum. Higher altitudes would unnecessarily limit operational flexibility and do not meet the criteria for restricted low approach scenarios.

In contrast, the other altitudes presented (1,000 feet, 750 feet, and 1,500 feet) exceed the established minimum. These higher altitudes do not provide the necessary conditions or requirements for a restricted low approach, making 500 feet the correct answer.
