Abstract:
|
In order to support the development of remote sensing technologies, the requirements of cockpit
information systems for flight operations in icing conditions were investigated. Pilot information
needs were investigated in a web-based survey. Results identified important information
elements, frequently used information paths for obtaining icing-related information, and data on
significant icing encounters and key icing-related information and decision criteria. In addition,
the influence of potential ice detection system features on pilot decision-making was investigated
in a web-based experiment. Results showed that the use of graphical displays improved pilot
decision-making over existing text-based icing information. The use of vertical view was found
to support better decision-making. Range enhancement was not found to have strong positive
influence; however the minimum range tested was 25 nautical miles, which may be in excess of
current technical capabilities. The depiction of multiple icing severity levels was not found to be
as important as accurate information on the location of icing conditions. This may have
significant impact for remote sensing and forecasting efforts currently under way, as the
technical challenges for accurate detection of icing presence may be significantly inferior to
those of accurate detection of multiple icing severity levels. |
