Anthropometric evaluation of cockpit designs

Area of Science:

• Human Factors Engineering
• Aerospace Ergonomics
• Pilot Physiology

Background:

• Effective cockpit design is crucial for pilot performance and safety.
• Ensuring adequate visual access and reach envelopes accommodates a diverse pilot population.
• Previous studies highlight variability in pilot anthropometry impacting cockpit fit.

Purpose of the Study:

• To evaluate critical cockpit dimensions and visual sufficiency for 90% of potential pilots.
• To identify ergonomic mismatches and propose improvements for cockpit design.
• To determine the relationship between pilot stature, eye level, and visual angles.

Main Methods:

• Anthropometric measurements and reach evaluations within a representative cockpit.
• Statistical analysis, including regression modeling, to predict visual sufficiency.
• Calculation of control limits for key cockpit measurements.

Main Results:

• Most cockpit dimensions were found to be acceptable for pilot accommodation.
• Eye level and associated visual variables were identified as critical areas needing improvement.
• Strong positive correlations were found between stature, eye level, and visual angle (R² > 0.97).

Conclusions:

• Cockpit design is generally suitable for pilot fit and reach, with exceptions in eye level and visual parameters.
• Adjustments to seating height and display panel positioning are recommended to enhance visual sufficiency.
• Optimizing seat adjustments can resolve identified ergonomic issues for a wider pilot demographic.
