I was coming up with ways to make my airliners more realistic and stop a bit faster and the one way I came up with was thrust reversers much like real airplanes. I figured out by taking a larger engine Building a Nacelle around it and adding a smaller forward facing jet with the activation on "Brake" you can achieve pretty realistic stopping distance
