A study was made of the effect of airflow disturbance aft of the ramp and in the landing area on the pilots ability make a precise carrier final approach and landing. Tests conducted on board USS MIDWAY CVA-41, USS RANGER CVA-61, USS CORAL SEA CVA-43 and USS SARATOGA CVA-60 determined that, from the pilots viewpoint, a Wind-Over-Deck WOD of 25 kt for jet and 15 kt for propeller airplanes is optimum. The determination of an optimum WOD was predicated upon operational feasibility as well as pilot considerations. A 25 kt WOD, in comparison with a 35 kt WOD, accrued the following advantages for jet airplanes Less demanding on the pilot reduction in landing gear loads improved approach airspeed control less deviation in alignment and increased jet recovery flexibility. The increased closure rate of a reduced WOD resulted in the following disadvantages Earlier wave-off initiation slightly degraded landing dispersion and increased bolter rate. Based on arresting gear andor airplane limits, fleet capability for utilizing a reduced WOD was determined.
