The following points are examined: pilot comments following the opening of the facility; the advisability of. a model study; the need for field wind measurements; the configuration of the helideck, including its location on the rooftop, dimensions, and the size of the air gap under it; and the effects of rotor downwash and temperature on helicopter power and lift. Recommendations for site measurement of wind characteristics and additional future work are given.en-USReport
