Managing operationalperformance to reduce risk in the execution of air traffic control (ATC) procedures depends on understanding human performance in relation to patterns established in procedures. Procedures specify performance requirements meant to minimize unintended variation that is outside expected performance criteria and tolerances.We define human performance risk as unintended variation outside theenvelope of applicable procedures.
