During phase I, the aviation research associates group proposes to develop a pilot judgment skills test battery for use on an IBM PC/XT applicable to the military pilot of high performance aircraft. This test battery will be designed to discriminate between judgment and decision making through the use of a conceptual model which identifies the types of instruments needed for each element in the judgmental process. Six basic tests are proposed for this battery as follows: knowledge, vigilance, recognition and diagnosis, alter native generation and selection, risk assessment, and risk-taking tendency. Each of the tests will be designed so as to permit the use of feedback for training purposes. A brief training test will be conducted to assess-the value of the package. The major systematic transfer of training programs will be conducted during phase II.
