Amendment of United States Area Navigation (RNAV) Route Q-436; Northcentral United States

Federal Aviation Administration (FAA), DOT.

This action amends United States Area Navigation (RNAV) Route Q-436 by changing the name of the “EMMMA”, MI, Fix route point to become the “KAYYS”, MI, Fix. The FAA is taking this action due to the similarly pronounced and sounding names of the EMMMA, MI, Fix and the EMMAS, WI, waypoint (WP) that is located approximately 200 nautical miles (NM) west of the EMMMA Fix. This action is an administrative change to match the Fix name change in the FAA's National Airspace Resource (NASR) database and does not affect the airspace boundaries, route alignment, or operating requirements of Q-436.

Effective date 0901 UTC, August 7, 2025. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order JO 7400.11 and publication of conforming amendments.

A copy of this final rule and all background material may be viewed online at www.regulations.gov using the FAA Docket number. Electronic retrieval help and guidelines are available on the website. It is available 24 hours each day, 365 days each year.
