Study on fair and equitable distribution of aircraft at Gatwick (2022)
Report
Torija Martinez, A., Clark, C., Lavia, L., Manuel, G., & Lomax, C. Study on fair and equitable distribution of aircraft at Gatwick

Fair and Equitable Dispersion (FED) was introduced in 2015 as an aspirational objective among others, by communities affected by noise from aircraft using London’s Gatwick Airport. The airport’s Noise Management Board (NMB) was established as a resul... Read More about Study on fair and equitable distribution of aircraft at Gatwick.
