Abstract
A system is presented for monitoring an alertness of an operator of a powered system which operates based on a profile. The monitoring system includes a controller to initiate a query to the operator during an operation of the powered system. The query is used to prompt the operator for information related to the operation of the powered system along the profile. The controller compares a response to the query with a correct answer of the query to determine the alertness of the operator.
