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

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.
