At the time, Mr. Trump told a reporter with The Palm Beach Post that he was flattered, but Thursday morning, he issued a statement that said:

“‘Making America Great Again’ is far more important to me than an honor I never knew I had ... meaning a blip on the radar,” he said in a statement released by Michael D. Cohen,executive vice president and special counsel at the Trump Organization.

Other navigation points were named IVNKA ONE, in honor of Mr. Trump’s daughter, Ivanka, and BUFIT ONE, after the singer Jimmy Buffett.

Ms. Brown said she wasn’t sure if IVNKA ONE would be renamed as well, but said that nothing would happen immediately.

“Because of the charting cycle, the updates could take several months to take effect,” she said.

The coordinate names are used for a type of instrument area navigation, called RNAV. The points entered into the computer should be five letters long and must be unique to that airport. Ideally, they relate to the area where the coordinates are located.

Mr. Trump has had a long history with the area, where his daughter, Tiffany, was born in 1993. He purchased Mar-a-Lago, an estate built in the 1920s for Marjorie Merriweather Post, in 1985. After renovating it, Mr. Trump opened the estate in 1995 as a private club, though he still maintains a residence there.
