When conducting ELPs (Tower or RSU), what is the minimum altitude below clouds that must be maintained?

When conducting Enhanced Low Visibility Procedures (ELPs) such as those involving a Tower or Remote Tower Service Unit (RSU), maintaining a minimum altitude below clouds is essential for safety and adherence to regulations. The requirement to maintain 500 feet below clouds helps to ensure that pilots have sufficient vertical separation from the cloud layer, allowing for better visibility and situational awareness. This altitude allows for safe navigation in reduced visibility conditions while also providing enough room for the pilot to recognize the terrain and avoid potential obstacles.

This specific altitude aligns with standard aviation regulations and practices intended to enhance safety during approach and landing phases when visibility may be limited due to weather conditions. The option of maintaining 500 feet below clouds specifically addresses the critical need for pilots to establish a clear visual reference while engaged in these procedures, promoting safer operations in low-visibility environments.
