Advancing vision standards in aviation: Embracing evidence-based approaches.

ABSTRACT: This study explores the relationship between visual acuity, contrast sensitivity, and pilot performance in simulated flight scenarios, including poor weather conditions, attempting to determine minimum visual requirements for safe flight. Twenty-six participants with normal or corrected-to-normal vision and varying flight experience (0-400 flight hours) completed simulated flight circuits under different weather conditions (e.g., rain, wind) using either Cambridge Simulation Glasses or defocusing lenses to degrade vision. Flight performance was assessed subjectively by an instructor using standardized criteria and objectively via simulator data. Visual acuity and contrast sensitivity were measured at each level of visual degradation. Mixed model analysis of variance revealed significant di
