determined with three steady loading conditions: design, low-loading, high-loading. The overall trend showed significant
(approximately 10 dB) increases in the generated noise for the highly loaded stator.

There are many challenges facing designers and operators of our next-generation aircraft in meeting the demands for
efficiency, safety, and reliability which are will be imposed. This paper discusses aeronautical sensor requirements for a
number of research and applications areas pertinent to the demands listed above. A brief overview will be given of aeronautical
research measurements, along with a discussion of requirements for advanced technology. Also included will be descriptions
of emerging sensors and instrumentation technology which may be exploited for enhanced research and operational
capabilities. Finally, renewed emphasis of the National Aeronautics and Space Administration in advanced sensor and
instrumentation technology development will be discussed, including project of technology advances over the next 5 years.
Emphasis on NASA efforts to more actively advance the state-of-the-art in sensors and measurement techniques is timely in
light of exciting new opportunities in airspace development and operation. An up-to-date summary of the measurement
technology programs being established to respond to these opportunities is provided.

The Evaluation of Two CDU Concepts and Their Effects on FMS Training
Abbott, Terence S.; [1995]; 6 pp.; In English; No Copyright; Avail: CASI; A02, Hardcopy
One of the biggest challenges for a pilot in the transition to a ‘glass’ cockpit is understanding the Flight Management
System (FMS). This is due to both the complex nature of the FMS and to the pilot-FMS interface. For these reasons, a large
portion of transition training is devoted to the FMS. The intent of the current study was to examine the impact of the primary
pilot-FMS interface, the Control Display Unit (CDU), on FMS training. The hypothesis of this study was that the interface
design could have a significant impact on training. An FMS simulation was developed with two separate interfaces. One
interface was similar to a current-generation design and the other was a multi-windows CDU based on graphical user interface
techniques. For both application and evaluation reasons, constraints were applied to the graphical CDU design to maintain as
much similarity as possible with the conventional CDU.
