The U.S. Air Force is taking public comment on a proposal to allow for low-altitude training in several areas of Arizona.
That could lead to training flights below 500 feet of altitude if approved.
The proposal covers portions of the state along the southern border and the New Mexico border, and also includes areas near Wickenburg and Lake Havasu City.
Public hearings have taken place in Arizona through August and will continue through this week in New Mexico.
In the draft statement, the Air Force says the changes in those areas are necessary as there is not enough airspace to conduct the training required. It also said the move will alleviate training shortfalls at Davis-Monthan Air Force Base , Luke Air Force Base, and Morris Air National Guard Base.
The Air Force is proposing to also lower the altitude for releasing flares to 2,000 feet and allowing supersonic flights to 5,000 feet.
A final decision on the draft is expected to come in the spring of next year.
