ABSTRACT
The demands placed upon aircrew are complex. In addition to the safe conduct of flight, they may be required to perform a multitude of additional tasks that vary with their role. These can be as extreme as search and rescue winchman duties, operating a door gun, or high-altitude airborne dispatch while at the other end of the scale steward duties and monitoring of data feeds are also regularly undertaken. What unites all of these is that they are conducted in any climate, by day and night and in all weather conditions.
