- Abstract
The aviation industry operates in an environment where forcing functions and catastrophes can be deadly to the public and not easily explained away. The industry formed a safety improvement collaboration known as CAST, the Commercial Aviation Safety Team. Within ten years, the fatal accident rate decreased from the pre-CAST rate by more than 80% while also improving productivity. Signals carry information while noise interferes with information. This distinction is one of predictability versus unpredictability. Noise as a stochastic variation may represent unrecognized influences in the system. By existing in a world of stochastic variation, biological systems must maintain dynamic stability far from equilibrium. The meaning of the types of environmental stochastic noise comes from the characteristics of their fluctuations that cause unpredictable events and the energy of their 'forcing functions.' Frequencies with the power to force a system or population to respond to the environment are forcing functions. White noise environments follow the Gaussian distribution and are amenable to prediction, algorithms, rules, and protocols. Red and pink noise develop from autocorrelation, the feedback from the past influencing the present or a system interacting with other systems. Red noise environments with low frequency forcing events have a greater influence on the system than white noise. Red noise environments contain ill-structured problems requiring the use of heuristics and experience. Considered a response to reddened frequencies, we can discuss safety as information about long-period events and forcing functions or as the forcing function itself. The threat of punishment and litigation incentivized pilots, as it currently does healthcare professionals, to hide their errors and near misses and not report the errors and near misses of others.
