The use of multiple physiological measures to determine flight segment in F4 pilots

Discriminant analysis techniques were used to classify flight segments for ten F-4 pilots from data recorded during air-to-ground training missions. Cardiac and eye blink parameters were used as variables, and 93% correct classification was found. It is concluded that this is a quite good result, especially since the combined measures correctly classified all of the segments for 6 of the 10 pilots, with the lowest percentage of correct classification being 80%. This indicates that this method should be considered for use in situations where pilot state and workload must be known. Application of this technique to flight environments of the future is discussed
