It's possibly if the air nomads where wiped out, that like aang giving korra energy bending that the previous avatars would have had to train the new avatar in air bending. also aang was the only known descendant of an air bender, there may have been other people that didn't know they were of the air nation and the avatars would give them the ability to air bend as next avatars then having kids and starting the air nomads again.
