Which airport corresponds to the ICAO code KPNS?

The ICAO code KPNS corresponds to Pensacola Airport, which is located in Florida. Each airport is assigned a unique ICAO code that is a four-letter alphanumeric designation used for air traffic control and other purposes. In the case of KPNS, the "K" indicates that this airport is in the United States, and the "PNS" is specific to Pensacola. This airport serves both commercial and military aviation, reflecting its importance in the region.

The other choices represent different locations or facilities that do not share the same ICAO designation as KPNS. Pine Bluff, Robbins AFB, and San Antonio have their own distinct ICAO codes, which are used to identify them uniquely in air traffic operations. This specificity of ICAO codes is critical for ensuring accurate communication and navigation in the aviation industry.
