L. Vigeant-langlois et Rj. Hansman, Influence of icing information on pilot strategies for operating in icing conditions, J AIRCRAFT, 37(6), 2000, pp. 937-946
The influence of potential remote ice-detection system features on pilot de
cision making was investigated through a Web-based experiment. Display feat
ures including a graphical plan view depiction of icing severity, vertical
view depiction, single and multiple icing severity levels as well as sensor
range were varied in a part-task simulation experiment. Using information
from each display, pilots were presented with a set of four Eight scenarios
and probed on their routing decisions and comfort level with those decisio
ns. The experiment also included a subjective display preference evaluation
. Results show that all of the displays improved pilot decision making over
existing text-based icing information. The three-dimensional displays that
included vertical depiction of icing conditions were found to support impr
oved decision making. Range was not found to be a strong factor in the expe
riment; however, the minimum range tested was 25 n miles, which may be in e
xcess of current technical capabilities, The depiction of the severity of i
cing conditions was not found to be as important as accurate information on
the location of icing conditions.
