What is the delta altitude for KNGP, KNWL, KRKP, and KTFP?

The delta altitude for KNGP (Naval Air Station Corpus Christi), KNWL (Hugh G. Smith Army Airfield), KRKP (Port Isabel-Cameron County Airport), and KTFP (Harlan County Airport) is established based on specific air traffic control guidelines and local regulations. Selecting 2000 feet MSL (Mean Sea Level) as the delta altitude indicates a standard altitude used in these airspaces.

This altitude is significant in ensuring the safe separation of aircraft operating in the vicinity of these airports. It provides an appropriate buffer to account for factors such as terrain, obstacles, and standard safety margins in aviation operations. The use of this altitude helps to maintain safe vertical separation between different air traffic, especially in areas where multiple airports may have intersecting flight paths.

Understanding these altitudes is crucial for pilots and air traffic controllers to avoid potential conflicts and enhance operational safety in controlled airspace.
