## Abstract

The FAA is amending its airports and locations special operating restrictions regulation to clarify a minor discrepancy in terminology. This amendment standardizes the language used to describe the altitude at which aircraft operating within 30 nautical miles of the listed airports are required to be equipped with an altitude encoding transponder. This action is not making any substantive changes to the regulation.
