Wing Pecking
Have been reading a book by Eric Brown which has left me with a few items that I thought I might ask about. One is Wing Pecking. In the chapter about the Gloster Meteor, he talks about high speed flight and says: "The compressibility characteristics displayed were a nose-up pitch with a porpoising motion, accompanied by strong wing pecking, the latter being the limiting factor."
Details(that are not too technical) are welcome.
