Final answer:
Part 2 of a flight physical, or FDME, is a detailed examination of a person's fitness for aircrew duties, whereas FDHS is a less comprehensive, regular health check-up for those already certified.
Step-by-step explanation:
Part 2 of a flight physical exam typically involves a more detailed examination of a person's health status following the general assessment in Part 1. The FDME (Flight Duty Medical Examination) is an in-depth medical exam that evaluates an individual's fitness for aircrew duties. It includes a thorough evaluation of the cardiovascular, neurological, musculoskeletal, vision, and hearing systems, among others. The FDHS (Flight Duty Health Screening), on the other hand, is often a less comprehensive screening that may focus on monitoring the health and wellness of individuals who have already been deemed fit for flight duties. It can serve as a more regular check-up to ensure ongoing compliance with health standards required for flight.
