President Barack Obama's brief trip through Anchorage en route to Asia Saturday will ground some flights for a few hours.
A Federal Aviation Administration temporary flight restriction is in place from 4 p.m. through 7:15 p.m.
"Please plan ahead," Anchorage's Merrill Field airport manager Paul Bowers warned in an advisory issued Friday.
The president is on a refueling stop on his way to a trip to Asia. He's expected to be the first president to visit Hiroshima, the site of one of the two nuclear bombs dropped by the U.S. at the end of World War II.
The flight restrictions ground all operations within an "inner ring" 7-mile radius except law enforcement, military aircraft supporting the Secret Service, approved air ambulance flights and scheduled commercial passenger and cargo flights. The restriction asks operations outside that inner ring but within a larger 30-mile radius from Girdwood to Willow to limit activity and stay in radio contact with air traffic controllers.
