Small Airport Capacity Modeling Factors

Principal Investigator(s) 

Lovell, David J.


Federal Aviation Administration

This project is a joint effort between researchers at the University of Maryland and the Ohio State University. The Federal Aviation Administration is interested in developing new capacity modeling factors for small aircraft operations at busy general aviation airports, as current estimates for small airport operating capacity are dated. This research seeks to identify specific data that will contribute to the development of modernized airport capacity models for small aircraft operations.
