21.0 Time of Useful Consciousness
“Time of useful consciousness (TUC) is defined as the amount of time an individual
is able to perform flying duties efficiently in an environment of inadequate oxygen
supply. It is the period of time from the interruption of the oxygen supply or exposure
to an oxygen-poor environment to the time when useful function is lost, and the
individual is no longer capable of taking proper corrective and protective action. It
is not the time to total unconsciousness. The TUC has also been called Effective
Performance Time (EPT).” – Wikipedia.
