Standard Instrument Approach Procedures; Miscellaneous Amendments

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) for operation at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to provide safe flight operations under instrument flight rules at the affected airports.
