Task loading
A task load indicates the degree of difficulty experienced when performing a task, and task loading describes the accumulation of tasks that are necessary to perform an operation. A light task loading can be managed by the operator with capacity to spare in case of contingencies. Task loads are primarily associated with underwater diving. They are also associated with workloads in other environments, such as aircraft cockpits and command and control stations. In underwater diving, task loading increases the risk of failure by the diver to undertake some key basic function which would normally be routine for safety underwater. A heavy task loading may overwhelm the diver if something does not go according to plan. This is particularly a problem in scuba diving, where the breathing gas supply is limited and delays may cause decompression obligations. The same workload may be a light task loading to a skilled diver with considerable experience of all the component tasks, and heavy task loading for a diver with little experience of some of the tasks. Excessive task loading is implicated in many diving accidents, and may be limited by adding tasks one at a time, and adequately developing the requisite skills for each before adding more. Excessive task load can be referred to as task overload and task saturation.
