Definition
The branch of ergonomics concerned with how the human body's anatomical, physiological, and biomechanical characteristics relate to physical activity, including the design of workstations, controls, displays, and tools so they fit the operator's body and movement.
Plain English
The study of how to design equipment and workspaces so they fit the human body well — making things easier to reach, see, hold, and operate without strain or injury.
Context Anchor
Seen in human factors, cockpit design, aircraft maintenance, and discussions of pilot workload or fatigue.
Derivation
From Greek 'ergon' (work) and 'nomos' (law) — literally 'the laws of work.' 'Physical' narrows the focus to the body itself, as opposed to cognitive ergonomics (mental workload) or organizational ergonomics (team and process design).
Why Pilots Care
Good physical ergonomics helps pilots maintain precise control and avoid fatigue on long flights.
Analogy
A well-adjusted driver’s seat in a car is a simple example. If the seat, pedals, mirrors, and steering wheel fit the driver, the driver can control the car with less effort and fewer distractions.
Intuition Check
Physical ergonomics is not just about comfort. It is about making the physical setup fit the person so the job can be done safely and accurately.
Example Sentence 1
Physical ergonomics influenced the placement of the landing gear lever so it could be reached easily without the pilot looking away from the instruments.
Example Sentence 2
Engineers improved physical ergonomics by adjusting the seat height and control spacing.
