A Looming Pilot Shortage: It Is Time To Revisit Regulations, Christopher L. Caraway Jan 2020

A Looming Pilot Shortage: It Is Time To Revisit Regulations, Christopher L. Caraway

International Journal of Aviation, Aeronautics, and Aerospace

Forecasts predict we will need 790,000 pilots by 2037. This prediction means airlines will need to increase pilot levels by 267%. Finding a solution to this pilot shortage requires the aviation community to address limiting regulatory and other core factors. Many have claimed that 1,500-hour rule and mandatory retirements are critical issues contributing to the pilot shortage. However, the data does not support these claims. Instead, trends in pilot population levels and safety records indicate these regulations are only effecting the demographics of the current pilot population. The shift in the pilot population will harm future airline operations if the …
