Establishment of Area Navigation Instrument Flight Rules Terminal Transition Routes (RITTR); Cincinnati, OH

This action establishes three Area Navigation Instrument Flight Rules Terminal Transition Routes (RITTR) in the Cincinnati, OH, terminal area. The FAA originally proposed to establish four routes as part of this action, but one route (T-212) was deleted because it did not meet RITTR design criteria and its short length would provide limited benefits. RITTR's are low altitude Air Traffic Service (ATS) routes, based on Area Navigation (RNAV), for use by aircraft having Instrument Flight Rules (IFR)-approved Global Positioning System (GPS)/ Global Navigation Satellite System (GNSS) equipment. The FAA is taking this action to enhance safety and facilitate the more flexible and efficient use of the navigable airspace in the Cincinnati terminal area.
