hover height

Two of the three criteria perscribed to meet the American Helicopter Society Sikorsky Prize competition were achived, with only hover height falling short.

It was later found that the craft's hover height was improved by the addition of a skirt of flexible fabric or rubber around the hovering surface to contain the air.

He deliberately released several of the systems in order to speed up the operation, taking over the cab manually for positioning and by allowing the PCS to find the hover height of forty feet.

Demonstrated at the Farnborough Airshow in 1960, it was shown that this simple craft could carry a load of up to 12 Marines with their equipment as well as the pilot and co-pilot with only a slight reduction in hover height proportional to the load carried.
