AB- This paper describes a piloted simulation conducted on the NASA Ames
Vertical Motion Simulator. The objective of the experiment was to
investigate the handling qualities benefits attainable using new
display law design methods for hover displays. The new display laws
provide improved methods to specify the behavior of the display symbol
that predicts the vehicle's ground velocity in the horizontal plane; it
is the primary symbol that the pilot uses to control aircraft
horizontal position. The display law design was applied to the Apache
helmet-mounted display format, using the Apache vehicle dynamics to
tailor the dynamics of the velocity predictor symbol. The
representations of the Apache vehicle used in the display design
process and in the simulation were derived from flight data. During the
simulation, the new symbol dynamics were seen to improve the pilots'
ability to maneuver about hover in poor visual cuing environments. The
improvements were manifested in pilot handling qualities ratings and in
measured task performance. The paper details the display design
techniques, the experiment design and conduct, and the results.

AB- The operation of control systems has been determined largely by
mechanical constraints. Compatibility with the characteristics of the
operator is a secondary consideration, with the result that control may
never be optimal, control workload may interfere with performance of
secondary tasks, and learning may be more difficult and protracted than
necessary. With the introduction of a computer in the control loop, the
mode of operation can be adapted to the operator, rather than vice
versa. The concept of natural control is introduced to describe a
system that supports control of the information used by the operator in
achieving an intended goal. As an example, control of speed during
simulated approach to a pad by helicopter pilots is used to contrast
path-speed control with direct control of global optical flow-pattern
information. Differences are evidenced in the performance domains of
control activity, speed, and global optical flow velocity.
