eral followed by an overview of the unique characteristics of pilot commuting. The chapter also includes a review of stakeholder comments that were either provided to the committee or obtained through an analysis of public comments submitted to the FAA on the NPRM. The chapter concludes with a discussion of aviation industry characteristics that are relevant to the effects of commuting on pilot fatigue, including airline pilot hiring policies; airline crew schedules and pilot work patterns; airline route networks and crew basing; and competitive and external factors.

Chapter 3 provides background information on aviation safety, including sources of safety improvement, followed by an analysis of information on fatigue-related aviation accidents from reports by the NTSB. The chapter concludes with a discussion and analysis of pilot commuting patterns that exist today.

Chapter 4 provides an overview of the relevant science related to sleep, circadian rhythms, and fatigue. Chapter 5 includes a discussion, followed by illustrative examples, of aspects of pilot commuting that contribute to the risk of fatigue.

The concluding Chapter 6 discusses ways to reduce the risk from fatigue caused by commuting. The chapter begins with background information on the current regulatory context followed by a discussion of fatigue risk management strategies for airlines. The committee’s recommendations are presented at the end of Chapters 5 and 6.

Following the list of references, a glossary and an acronym list are provided. Additional background information, data sources, and analyses are included in the seven appendices. Appendix A identifies the airlines, associations, and groups that submitted documents for the committee’s review. Appendix B provides the agendas for the committee’s open meetings, which list the organizations and individuals that presented before the committee and responded to its questions. The committee conducted a thorough review of all the documents submitted by airlines, associations, and groups as well as a few individual pilots; a summary of its review is included in Appendix C. In addition, the committee examined public comments in response to FAA’s NPRM that related to commuting. Appendix D presents a summary of the analysis of that purposeful sample of public comments. An analysis of scheduled aircraft departures for the third quarters of 2000, 2005, and 2010 is discussed in Chapter 2. The data for this analysis in number of aircraft departures by airline and by city are available in Appendix E for mainline airlines and in Appendix F for regional airlines. Also provided in Appendix E is a list of airport codes alongside the corresponding airports and cities. The final appendix (Appendix G) includes the biographical sketches for the committee members and staff.
