il caldo 2010 spagnolo in un post, ma su PPrune se ne trovano a decine:
ATC situation in Spain
e poi la nascita di FerroNats con cessione dei servizi ATS di svariati aeroporti "minori" a nuovo provider anglospagnolo (con CTA non AENA che viaggiano a stipendio moolto ridotto)
FerroNATS
NATS, through its Airports Service Line, established an alliance with Spanish partner Ferrovial in 2011, forming ferroNATS,[7] which provides air traffic control (ATC) services at nine airports across Spain: Alicante, Valencia, Ibiza, Sabadell, Sevilla, Jerez, Melilla, Madrid Cuatro Vientos, Vigo and A Coruņa airports in Spain. FerroNATS was awarded the contract to provide services at these airports through a competitive tender process run by the Spanish aviation authority, AENA. All nine operational handovers were completed between November 2012 and January 2014.
