The move, which will not apply to future control towers, comes as Dayton International Airport officials are awaiting federal approval on a new master plan for the airport on Springboro Pike in Miami Twp.
It also comes at a time when airport and Miami Twp. officials have been discussing long-range plans for further development at the 527-acre site. There have been preliminary talks about expanding the Miami Twp.-Dayton Joint Economic Development District to include land in Washington Twp. east of the airport.
