If its a for a personnal aviation website $0. If it was to be used in the press like a magazine, it really depends on the photo. The real truth, is the press will offer you a price, not you offer them a price. Thats usually how it goes.
From what I hear, photographers get paid around $200 for a photo to be used in the press in some way. It changes though depending on the value of the photo. Its quite difficult to give you a specific price, it depends on the photo and the way it is being used.
