Temporary Airports are Airports that are established by Rigs. They were introduced in Advance Wars: Days of Ruin, and can be differentiated from standard Airports by their ability to only resupply units based within them.
Unlike Airports, Temporary Airports do not provide any income, nor can they build, or repair air units based upon them. Their defence rating is only one star, compared to the three stars a standard Airport provides. As previously mentioned, Rigs establish Temporary Airports, however the only terrain they can establish on are plains.
