Vigo: A New Frontier in Air Traffic Control with Spain’s First Digital Tower
Announced as the forefront of efficiency and security in the aviation sector, the airport in Vigo has commenced operations with what is being touted as “the first digital tower in Spain.” Just four days after its launch, operations were halted due to a significant issue. This situation raises questions about the system’s actual effectiveness, the future positions for workers, and the looming specter of layoffs.
Vigo’s Digital Tower. This transformation was heralded by Óscar Puente, the Minister of Transport, who heralded the news on Twitter. On June 17, he announced that Vigo was undergoing a transformative shift in its operational methodology.
The project began with a flight from Vigo to Madrid, which Puente celebrated as “a technological milestone” that places Vigo at the cutting edge . However, only four days later, the system experienced a failure just 31 minutes after going live.
What is a Digital Tower? A digital tower replaces traditional air traffic control towers. In conventional settings, controllers manage air traffic from great heights using computer systems and visual sight. The objective is to always choose the best options for managing incoming and outgoing flights under maximum safety conditions.
The digital tower employs similar computerized systems but replaces the traditional “windows” of a control tower with screens displaying live feeds from cameras. Additionally, it features numerous sensors and microphones meant to replicate the experience of what a traditional air traffic controller would feel.
Is it an Improvement? According to Minister Puente, the answer is a resounding yes. Furthermore, AENA also asserts that the use of a video wall made up of 13 55-inch monitors provides a 360-degree view of the airfield, offering visibility in areas obscured in traditional towers.
The installation also includes fixed and mobile cameras, alongside “speakers that reproduce the ambient sounds captured by microphones placed across the airfield.” Additionally, AENA claims that it “offers several operational and security advantages,” yet does not specify what those advantages are.
Importantly, they emphasize, “the number of controllers will remain the same .”
Controllers in an Uproar. This last point has been critical. On social media, numerous accounts representing the sentiments of air traffic controllers have expressed strong opposition to the implementation of these digital towers. The widely-followed account @controladores on X has described the digital tower as “a basement with cameras designed to oversee multiple airports.”
The underlying concern among workers is palpable. There’s an atmosphere of anxiety regarding the potential for the digital tower in Vigo to take over air traffic control for A Coruña as well. Alvedro (A Coruña) and Peinador (Vigo) are both managed by the same company responsible for air traffic control (Saerco), leading to fears of potential workforce reductions.
Reports by La Voz de Galicia even assert that AENA neither confirms nor denies whether workers in A Coruña could be replaced by the new digital tower control system. Both the BNG and the Popular Party are already mobilizing efforts to halt the project.
“Obvious Deficiencies”. As concerns over job security remain, the Union of Air Traffic Controllers (USCA) reports that AENA rejected their proposal to include “high-definition cameras.” They emphasize that the new system does not surpass traditional control towers as “small aircraft cannot be distinctly visualized.” In their words, these are “obvious deficiencies.”
They warn, as articulated in an article from Faro de Vigo, that the system faces operational restrictions, particularly under specific weather conditions. This could impose time constraints , preventing simultaneous visual (VFR) and instrumental (IFR) flights. Such issues are problematic for emergency medical transport, customs surveillance, wildfire response, seaside rescue missions, and even flight training scenarios.
Lingering Doubts. Despite AENA’s assertions that “over 30 European airports currently use this technology,” the operational feasibility of these digital towers continues to invite skepticism.
In fact, tests in Spain have been underway for several years. In 2023, issues were reported in Vigo’s digital tower related to the imprecise detection of small aircraft. Approved in 2019 and awarded in 2020, it wasn’t until this year that the first flights commenced.
A similar narrative unfolded in Menorca, where a digital tower is also undergoing trials. Reports from late 2022 indicated security concerns, and this air traffic control system was supposed to be operational by 2021 but has yet to successfully pass testing. Thus, Vigo became the first city in Spain to implement digital air traffic control, but the excitement lasted for a mere four days .

In conclusion, the advent of Vigo’s digital tower presents both exciting technological advancements and significant concerns that need addressing. As the aviation industry continues to evolve, the balance between technological innovation and workforce stability remains crucial for ensuring safety and efficiency.
