What is the recommended altitude when not previously established on course rules, according to the NORDO procedure?

The recommended altitude when not previously established on course rules, according to the NORDO (No Radio) procedure, is 3500' MSL above KNGP (Kingsville Naval Air Station). This altitude is established to provide a safe vertical separation from ground operations and other traffic, ensuring that an aircraft operating NORDO maintains an altitude that is consistent with typical traffic patterns and airspace requirements.

Choosing this altitude helps to mitigate the risks associated with operating without the ability to communicate, as it places the aircraft in a position where it is less likely to interfere with other aircraft and can facilitate easier management of the flight path. The selected altitude aligns with standard practice in the absence of established course rules, providing a guideline to maintain safety and operational integrity.
