the soundness and conservatism of pilot proficiency and performance capability of the twin-turbine helicopter. The helicopter has substantially less exposure than fixed-wing aircraft during the landing and take-off maneuver. From your own experience in flying in helicopters you have undoubtedly observed firsthand that the helicopter's slow speed flight capability and control response inherently provides a longer available pilot reaction time. The vertical landing and take-off technique provides more margin for judgement than the procedures used in operation of earlier single-engine helicopters. The helicopter is also less disturbed by weather and air traffic problems. There is simply no correlation possible between fixed-wing and helicopter operations in this region of flight.

Site selection and use, therefore, are determined initially by passenger convenience and accessibility, in other words, by the befits to be derived by the public.
