Landing tests were made with the EB2Y-6 flying boat to determine the effect of production step vents and forebody longitudinal steps on skipping. It vas found that skipping occurred at higher landing trims without either step vents or longitudinal steps. The step vents alle¬viated skipping somewhat but were not considered large enough to "be com¬pletely effective. The longitudinal steps caused a marked decrease in skipping which was not further affected by the addition of step ventilation.
