Alternative 3 is a variation of Alternative 2 for consideration. Under Alternative 3, the horizontal expansion of Tombstone MOA would not occur, but the floor of Tombstone MOA would still be lowered to 100 feet AGL. To make up for this loss of training airspace, the floor of the Jackal MOA would be lowered to 100 feet above ground level. The other proposed changes would be the same as Alternative 2.
Please review the Summary of Alternatives by Airspace to obtain more details on how these proposed changes affect each MOA.
