The inversion in these growth rates indicates another interesting statistic, which is that the average unit value will increase significantly. Summarizing then from a business point of view, we believe that there is an attractive rate of financial growth, coupled with a clear shift toward larger vehicles, which is a fairly typical aerospace trend.

The requirement for ease of air transportation physically limits the external dimensions of the Black Hawk in order to meet the internal dimensions of Air Force transport aircraft. The result is a passenger cabin envelope unsuited to civilian passenger standards.

the civil market potential revenue is a miniscule l.5 percent of total dollar volume and the lightweight class has shrunk from its 75 percent of units produced to only one-third of the total market revenue. I believe, therefore, that NASA should pursue areas involving the central core of the helicopter market -- the intermediate/medium class.

I believe it is generally agreed that the helicopter has reached only about 50 percent of its technical potential, whereas the fixed-wing subsonic transport is very close to maturity. Helicopter research will provide rapid and visible advances, whereas fixed-wing research will require increasingly heavier funding for relatively marginal gains.

They come under the general heading of improved operational capability and are as follows: -- Development of helicopter instrument approaches -- Noise abatement -- Dedicated helicopter airways -- Cockpit integration and human factors -- Crashworthiness In my view, success in these areas of research is essential if we are to enable the helicopter to play its appropriate role in relieving the traffic constriction in this country's air transport system. While the FAA also has a vital role to play in this arena, there is much that NASA can do to help.
