Introduction: Color is an important characteristic of the aviation environment. Pilots must rapidly and accurately differentiate and identify colors. The medical standards published by the International Civil Aviation Organization (ICAO) require that pilots have "the ability to perceive readily those colors the perception of which is necessary for the safe performance of duties.

- * The introduction of safety management systems in aviation offers a structured way to manage safety by organizing accountability, policies, and procedures effectively.
- * By applying safety management principles, improvements can be made in areas such as medical examination protocols, data reporting and analysis, and fostering a supportive culture for aeromedical event reporting among companies and regulators.
Aeromedical decision-making: an evidence-based risk management paradigm.

Aeromedical decisions take many forms and are made by different groups and individuals. Because of the ubiquity of aviation in the world today, it is important that aeromedical decisions are of the highest quality that can be reasonably achieved. A paradigm of evidence-based aeromedical risk management is reported on here.

In this study, auditory sensitivity to 1, 8, 12, and 16 kHz tones was compared between conditions of hypoxia and normoxia at the same simulated altitude (3700 m).
Method: In the hypoxic condition, the partial pressure of oxygen in the inspired air was allowed to decrease with increasing altitude.
