Pilots who will be flying in western Iowa during the period of Sept. 4 to 21 should be sure to check the status of a temporary military operations area (TMOA) that could affect their flight planning, including the availability of several Victor airways.
The Hawki TMOA was established at the request of the Air Force to support annual training exercises. The TMOA will be established underneath the existing Crypt MOA complex, as AOPA reported May 2.
Active altitudes have been designated from 4,500 feet msl up to but not including 8,000 feet msl. The TMOA’s active times are scheduled from Sept. 4 to 11 between 0900 and 2030 CDT; Sept. 16 to 21 between 0730 and 0100 CDT; and at other times by notices to airmen.
AOPA submitted formal comments May 15 noting concern that the TMOA could render two Victor airways entirely unusable during periods of TMOA activation, and adversely affect use of three other routes.
The association recommended raising the floor of the TMOA to 6,000 feet to allow for bi-directional IFR traffic floor of 4,500 feet because radar coverage for IFR flights in the area is not available below 4,000 feet—possibly causing extensive route changes for many flights.
The TMOA also could have an effect on the Iowa Aviation Promotion Group’s Fly Iowa airshow scheduled for Sept.15, in Atlantic, Iowa.
Pilots are urged to check notams frequently during the Sept. 4 to 21 period for active TMOA status and any changes to scheduled periods of TMOA activation.

Safety and Education
Two tragic accidents that occurred within a week of each other, involved pilot incapacitation at high altitudes.
George Perry recognized the signs quickly: Hypoxia is something he spent 20 years training for as a U.S. Navy fighter pilot and instructor.
AOPA is opposing an FAA proposal to decommission Bettles Airport’s approach lighting system because such a move could negatively impact IFR operations at the airport.
