published in the “Wehtpsychologische Untersuchungen”.). The condensation required 60 hours
of processing time, and the results were stored in 7 data banks for later ease of access.
In the second stage of evaluation, correlations were made between the individual variables and
the results from the later Plying screening. In this way the variables best able to predict the
results of the Plying screening were high-lighted.
In the third stage of evaluation, based on a regression analysis of the most predictive variables
from stage 2, a representative value for each candidate was calculated for the individual sections
of each mission, and also for each complete mission (or in the case of mission 02, for each circuit
of the mission).
The validity of the values for each complete mission thus caIculated were correlated with the
results of the Plying screening. All correlations were highly significant, but differed widely
between missions. The fact that the first mission had a lower correlation could perhaps be
explained by the unfamiliarity of the test environment at this early stage of FPS screening.
In a fourth evaluation stage, the fall-out frequencies during Plying screening within groupings
of candidates with similar PPS performances were computed. Table 2 (next page) shows clearly
that candidates with low PPS performances frequently failed the Plying screening.
The second mission appears to have been particularly predictive. Mission 3 and 4 show
irregularities in the middle stages, which could perhaps be explained by the fact that some. of
the skills being tested in these missions, do not play a part in the Flying screening.
Those particularly at risk from the Plying screening are candidates who scored below 51 in the
FPS (most candidates scored in the range 40 to 76). The group of candidates with the best FPS
results ( 69 FPS points) on the other hand, had a 90% success-rate in the Plying screening.
Conclusion
After exhaustive statistical evaluation, it was possible to conclude that the FPS was capable of
predicting success or failure at Plying screening with acceptable accuracy.
A final evaluation of the success of this method of screening (remembering that the full screening
process consists of all five stages in Phases 1 to 3, as at present Plying screening is being retained)
will only be possible after the collection of sufficient statistical evidence of candidates subsequent
performance in training and later operational flying. The same applies, of course, to the
other in-flight disciplines for which PPS screening takes place.
To date, second-rate pilot-candidates have been channclled into positions as Weapon System
Officers and Navigators. It is hoped that the specific results of FPS missions 3 and 4 will show
a better cormIation with subsequent candidate skills in these specialist activities.
