Reverse Out Of Gate
I was aboard a DC9 a few years ago, I forget just where---Detroit, I believe. The airliner was backed away from the gate using reverse thrust. I have seen AirTran DC9's doing same in Atlanta. My questions: do engines equipped with cascade-type reversers provide as much reverse thrust as the clam shell, or bucket-type reverser? Could a cascade-typer reverser provide enough thrust to back an airliner out of its gate?
