Altimeters
If the issue is interference with radio altimeters, why wouldn't this affect them in other areas as well as near an airport. If the reported altitude is incorrect, pilots are going to try get their assigned altitude. If they are flying on instruments this could lead to all sorts of accidents and near misses; assuming the problem is real. Also, 2nd or 3rd harmonics of the signals would be an issue around an airport; I have not looked up what is assigned those frequencies. The 2 bands are not harmonically related.
