Illness. Even a minor illness suffered in day-to-day living can seriously degrade performance of many piloting tasks vital to safe fight. Illness can produce fever and distracting symptoms that can impair judgment, memory, alertness, and the ability to make calculations.
To understand a flight level, we should understand how altitude is measured in an altimeter, which is essentially a calibrated barometer - it measures air pressure, which decreases with increasing altitude.
10 mar 2024 · Here’s the definition of a Flight Level by the ICAO (International Civil Aviation Organization): “A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals.”
aeromedical and human factors » Aeromedical & Human Factors. Introduction: The human body is the most important system on any manned aircraft. Influenced by external factors such as pressure, oxygen, and chemicals, the body can be incapacitated or degraded through a variety of means.
The Physiologic Zone is 0-10,000' and is the most common zone for air medical flight, specifically rotor-wing (RW) operations. A healthy human being can breathe within this range without requiring additional oxygen.
Strictly speaking a flight level is an indication of pressure, not of altitude. Only above the transition level (which depends on the local QNH but is typically 4000 feet above sea level) are flight levels used to indicate altitude; below the transition level feet are used.
1 lip 1992 · The term stresses of flight is commonly used to describe the conditions and physiologic effects that the air transport environment may place on the patient and crew.11 The nine stresses of flight are identified as hypoxia, barometric pressure, thermal changes, dehydration, noise, vibration, gravitational forces, third spacing, and fatigue.12.
