Regarding the second flight scenario, 20 runs were performed in the engineering simulator from a preprogrammed point shortly before the loss of engine thrust in which pilots attempted to return to either runway 13 or 22 at LGA or runway 19 at TEB. Five of the 20 runs were discarded because of poor data or simulator malfunctions. Of the 15 remaining runs, in 6, the pilot attempted to land on runway 22 at LGA; in 7, the pilot attempted to land on runway 13 at LGA; and in 2, the pilot attempted to land on runway 19 at TEB. In eight of the 15 runs (53 percent), the pilot successfully landed after making an immediate turn to an airport after the loss of engine thrust. Specifically, two of the six runs to land on runway 22 at LGA, five of the seven runs to land on runway 13 at LGA, and one of the two runs to land on runway 19 at TEB immediately after the loss of engine thrust were successful. One run was made to return to an airport (runway 13 at LGA) after a 35-second delay, and the landing was not successful.
