Understanding Body Mass Index (BMI)

Body Mass Index (BMI) is a commonly used measurement to assess a person’s weight in relation to their height. It provides a quick and easy way to determine if an individual is underweight, normal weight, overweight, or obese. BMI is calculated by dividing a person’s weight in kilograms by the square of their height in meters.

Formula:

BMI = weight (kg) / height2 (m2)

The resulting number is then compared to the standard BMI categories, which help classify a person’s weight status. These categories include:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI of 30 or higher

The Federal Aviation Administration (FAA) recognizes BMI as one of the indicators of a pilot’s health and fitness for flying. Pilots are required to maintain a healthy BMI within an acceptable range to ensure they are physically fit to perform their duties safely.

The Impact of Obesity on Aviation Safety

Any amount of excess weight, regardless of whether it falls under the classification of obesity, can have a significantly adverse impact on aviation safety.
