Analysis of Procedure Following as Concerned Work
Published in Erik Hollnagel, Handbook of Cognitive Task Design, 2003
The data we report here were collected as part of a research project exploring the design and use of procedures in commercial aircraft. As part of this project we interviewed commercial airline pilots about the documents they use when following procedures and the problems they encounter. One key document used by pilots is something referred to as a Quick Reference Handbook (QRH). This document is intended for use in the cockpit as a reference book for procedures. In an interview with one particular pilot about his use of the QRH, a fascinating and complex story emerged. The pilot provided us with a copy of a QRH that he owned. The QRH contained numerous pencilled annotations. An analysis of these annotations has been reported elsewhere (McCarthy, Wright, Monk, & Watts, 1998; Wright, Pocock, & Fields, 1998). We also interviewed the pilot about his life as a commercial airline pilot. In this context, he gave us an account of where his annotations came from, why they were made, how they feature in his ongoing work as an airline pilot, and what he intends for them in the future. It is this interview that forms the central part of the analysis of concerns. However, before we report this analysis, we provide some necessary background about procedures and the QRH in the modern commercial cockpit.

Working from the top of the hierarchy down, the control actions associated with each stakeholder for current operations are considered in turn. The regulator (top, Figure 2) provides an aircraft operating certificate (AOC) to the airline, allowing them to operate and charge to transport passengers and freight on its aircraft fleet (arrow from regulator to airline, top left Figure 2). The airline is then responsible for ensuring its crew is provided recurrent training with simulators for emergency and non-standard situations (arrow from airline to crew, Figure 2). In the event of a rapid decompression event, the crew is responsible for completing the quick reference handbook (QRH) drills to ensure both adequate oxygen levels for the crew and adequate pressure levels in the cabin. This includes donning oxygen masks, and descending to 10,000 feet - terrain permit (arrow from crew to aircraft, Figure 2). CAs also exists between the crew and ATC/ATM (arrow from crew direct to ATC/ATM, far left of Figure 2) with a Mayday call made by crew (including route and aircraft position changes resulting from the incident). The interrogation of the onboard transponder (identifying aircrafts position, altitude and call sign) represents a CA from ATC/ATM to the aircraft.
