Abstract:
The feasibility of constructing a device to give a measure
of pilot reliability has been investigated. A rig to meet the proposals
made by BLEU has been designed and basic circuits constructed and tested
for accuracy of operation and reliability. An estimate of the materials
required and the cost of construction has been made.
The rig has been designed to be subject operated for twentyfour
tests before requiring attention, and devices have been incorporated
to indicate unserviceability and prevent operation if starting cond4 tions
are not correct.
Switching sequences typical of the final period of an autoland
approach are demanded verbally by magnetic tape replay equipment and the
performance of the subject measured. The test consists of two phases;
a preparatory or "unloaded" phase, and a "loaded" phase during which
the subject performs a tracking task in addition to the switching
sequence. The performance of the subject is recorded on veeder counters
for both phases of the test in the form of actions demanded, actions
taken and actions taken during a memory period. A measure of performance
of the tracking task is also given by veeder counter.
