- Flightcrew Member Line Operational Simulations: Line-Oriented Flight Training, Special Purpose Operational Training, Line Operational Evaluation
- Date issued
- Office of Primary Responsibility
This advisory circular (AC) presents guidelines for the design and implementation of Line Operational Simulations (LOS), including Line-Oriented Flight Training (LOFT), Special Purpose Operational Training (SPOT), and Line Operational Evaluation (LOE) for flightcrew members. This document does not interpret the regulations; interpretations are issued only under established agency guidelines. As operators develop LOSs, they should develop an interdependent relationship between their human factors, Crew Resource Management (CRM), flight operations, and safety initiatives, because they are linked to a common safety goal.
This AC describes a means by which LOS scenarios are developed, scripted, tested, evaluated, and (in the case of LOFT and LOE) approved by the Administrator for use in an operator’s training program. The methodology set forth also achieves the Federal Aviation Administration’s (FAA) mandate to ensure that each certificate holder provides the highest level of safety in the public interest, while meeting the agency’s responsibility to reduce or eliminate the possibility or recurrence of accidents in air transportation.
