Table 2 Pre-flight: individual and group mean and SD of the touchdown parameters for all pre-flight trials; touchdown (TD) speed (KIAS), landing force (lbs), distance (range) of touchdown from the runway threshold (km), vertical sink rate (Hdot ft/s), and height over runway threshold (ft).

  1. POST-FLIGHT: individual touchdown parameters for the four post-flight landing simulations, two on the day of return (R + 0–1) and one each on R + 3–4 and R + 7–9. Post-flight group mean is also shown.
