README for "Determining if There Is a Medical vs. Human Factors/Experience Risk Tradeoff in Pilots Operating Under BasicMed [supporting dataset]" dataset.

Dataset archive link: https://doi.org/10.21949/1528566 ---------------------------------------------------------------- SUMMARY OF DATASET ---------------------------------------------------------------- The purpose of the study is to determine if there is a medical vs. human factors/experience risk tradeoff for pilots operating under BasicMed. The hypothesis would be that, while the rate of mishaps caused by medical factors is greater for older pilots, the rate of mishaps caused by human factors is lower for these pilots. METHODS. The analysis followed three steps: (1) examine the ratio of medically caused mishap rates to human factors/experience caused mishap rates for BasicMed pilots by age decade, (2) examine the similar ratio of medically caused mishap rates to human factors/experience caused mishap rates for 3rd class medical certificate pilots by age decade, and (3) compare the mishap rate ratios determined in steps 1 and 2 among age decade. ---------------------------------------------------------------- TABLE OF CONTENTS ---------------------------------------------------------------- A.

Description of methods used for collection/generation of data: Flight hour counts for 3rd Class Medical pilots are based on reported flight hours for last six months from most recent medical exam. Hours are reported by the pilots are not independently measured. Annual hours are extrapolated from those reported for the most recent six months. Flight hour counts for BasicMed pilots are based on those 3rd Class Counts. Since BasicMed requirements do not include the same level of medical examination or reporting there is no direct basis for determining BasicMed hours flown by pilot. The three-year period, 2017 through 2019, yields a useful, representative sample of mishap and flight hour data. The BasicMed program began in 2017, so no BasicMed data before that year. The pandemic caused the years 2020 and 2021 to be anomalous in terms of flight. hours, and flight and mishap data after 2021 is currently incomplete. The analysis followed three steps: (1) examine the ratio of medically caused mishap rates to human factors/experience caused mishap rates for BasicMed pilots by age decade, (2) examine the similar ratio of medically caused mishap rates to human factors/experience caused mishap rates for 3rd class medical certificate pilots by age decade, and (3) compare the mishap rate ratios determined in steps 1 and 2 among age decade. 2.
