The experiment is of the explorative type seeking to establish if the BCG task could be executed during flight and if it gives an indication of the pilot spare information handling capacity as a workload measure.

Material and Methods.
Two pilots flew the Rotterdam Overshoot Procedure (2 times each) in a DC-7 flight simulator (see experiment 5 in the list of the contents window on the left).
The BCG was used in the aural mode, the tones emitting from the pilots headset.
Required responses were pressing one of two little buttons spaced approximately 1 cm apart on a small strip fixed on the left top side of the control column, close to the place were the column is normally held.
Samples of BCG performance are taken in 5 experimental conditions (flight phases) supposedly increasing in mental load. The conditions are similar to those as in the experiment 5 just mentioned and the characters on the horizontal axis have the same meaning.
Results are given in figure 1.

The general trend is in the predicted direction, except when comparing take off and approach.
It is felt that the possibility of using the BCG as a workload measure quantifying spare information handling capacity during the flight task has been demonstrated. The curve of relationship between treatment and dependent variable is very similar to the trend of the physiological variables as in the other relevant experiments above. The discrepancy between the values for take-off and approach also occurred in these experiments.
