What altitude should be maintained over the Lexington when arriving at KNGP?

The correct altitude of 1,000 feet MSL is specified for maintaining safe vertical separation and compliance with air traffic control requirements when approaching KNGP (Naval Air Station Kingsville). This altitude is often used in the context of standard arrival procedures in a controlled airspace, particularly when approaching relatively busy airfields where specific altitude thresholds help manage traffic and ensure safety.

When arriving at KNGP, maintaining 1,000 feet MSL helps ensure that arriving aircraft are compliant with local procedures while providing adequate separation from the airport environment and any potential obstructions in the area. This altitude is typically intended to keep traffic out of the way of departing flights and operations on the airport.

Other altitudes listed may not provide the necessary clearance or may conflict with other aircraft in the vicinity, making the choice of 1,000 feet MSL the most practical and safest option for the given approach.
